Zipp vs. ENVE

By Bruce Lin

Ali and Frasier. Tyson and Holifield. Mayweather and MacGregor. When it comes to a heavyweight bout between lightweight carbon road wheels, Zipp and ENVE are the top contenders.

If you’re ready to turn your road bike into a high-performance machine, carbon wheels are the best starting point. And if you want some of the most desirable, best-selling wheels with industry-leading technology and quality, Zipp and ENVE are the two top choices. They are the most sought-after wheels we sell.

ENVE American made

Plenty of manufacturers make great carbon wheels, but most are made overseas. Both Zipp and ENVE manufacture their carbon rims here in the U.S. Staying American-made gives them control over the entire process through design, prototyping, testing, and production, and it helps maintain higher levels of quality control. It also allows them to quickly develop new, cutting-edge technology because they don’t have to wait for an overseas manufacturer to test ideas or make revisions. This is why Zipp and ENVE are the tech leaders for bike wheels. 

If you’re looking to upgrade to a set of Zipps or ENVEs, how do you choose which is right for you? We can't definitively answer whether one wheel manufacturer is “better” than the other (sorry). Instead, this comparison aims to explore the history of the two wheel makers, the technology they use, and the features they offer. We will also consider their popularity among our customers and employees.

History

Zipp Speed Weaponry

Zipp HeadquartersZipp headquarters is within sight of the Indianapolis Motor Speedway and its story begins in motorsport. Founder Leigh Sargent cut his teeth as an engineer for the Williams Formula 1 race team in England. He moved to the U.S. to work with a CART team, and after the team folded, he stayed in Indianapolis running a shop specializing in chassis repair and carbon fiber nose boxes and wings for race cars. Up until 1999, Zipp products were still manufactured and wind-tunnel tested alongside race car components.

original zipp discIn 1988, one of Sargent’s drivers happened to be a cyclist. This driver brought a 3,000-gram aluminum Mavic disc wheel (cutting edge at the time) into the shop and Sargent immediately saw that he could do better. The first disc wheel he made weighed half as much as the Mavic and was constructed from Nomex honeycomb originally used for chassis tubs in race cars. After showing it off at the Interbike trade show, there was immediate interest. By 1990, he had refined it into a disc wheel weighing only 1,150 grams, which is still competitive with many current disc wheels.

Wind-tunnel testing set Sargent’s wheels apart from the competition. With his motorsports background, it came naturally, but in the cycling world, this was still uncommon. Zipp was one of the first cycling companies to use wind drag data in product development. Today, aero testing is a cornerstone of modern road bike and wheel development.

Zipp tri spoke 2001Zipp created the first tri-spoke wheel in 1989 to give riders an aerodynamic option for front wheels. Three years later, it introduced the 2001 aero beam frameset which used a massive wing-shaped downtube, no seat tube, and a flexible beam for the top tube and saddle. Through the 1990s, these products gained a considerable foothold in the growing triathlon scene and earned Zipp a reputation as one of the most technologically progressive brands in cycling.

Even with the great success of the tri-spoke, Zipp’s engineers weren’t satisfied and kept improving their designs. In the wind tunnel, they saw that the performance of the tri-spoke wheel could be bettered by a deep-section wheel design with spokes. Compared to a tri-spoke, deep-section wheels are equally fast but less affected by crosswinds. They also pass through the air more cleanly, leaving fewer wakes and turbulent air. In 1992, the original 440 deep-section carbon wheelset went to production. Zipp’s deep-section wheels were the first of their kind and had a huge influence on aero wheel design for the years to come.

Zipp also experimented with other cutting-edge component technologies like carbon mountain bike cranks and wheels nearly a decade before they became popular. But when Zipp (the cycling company) split from Compositech (Sargent’s motorsports business) in 1998, the focus shifted to road cycling. Leigh Sargent’s original employee, Andy Ording, bought the cycling side of the business and refocused it on road development, bringing a host of new aero technology to carbon road wheels.

In 2007, component manufacturer SRAM purchased Zipp, and three years later, Zipp made history when Fabian Cancellara became the first rider to win Paris-Roubaix (and Tour of Flanders) on carbon wheels riding a prototype 303 wheelset. Victory in the most rugged WorldTour race proved that carbon wheels were the future of cycling.

ENVE Composites

ENVE HeadquartersENVE Composites is based on the other side of the Continental Divide in Ogden, Utah. Entrepreneur Jason Schiers founded the company under the name EDGE. Just before starting it, Schiers ran a machine shop in Las Vegas making a number of custom products including safety harnesses and stunt contraptions for Cirque du Soleil.

Schiers discovered the world of carbon fiber while in the machining industry. He did composite and laminate work for aerospace projects and NASCAR. With this inspiration, he decided to start a new company to make structural carbon parts for cars. But after he spent a couple of years riding and working in the bike industry, he decided he wanted to make bike components.

EDGE Composites started in 2005, stuffed in the corner of a 5,000-square-foot building that housed a long-travel dune buggy manufacturer. One day, the dune buggy owners, Brett and Taylor Satterthwaite, asked him to make custom carbon parts for their closet full of ultra-high-end mountain bikes. They became his first investors.

Eventually, the company grew to the point where it pushed the dune buggy company out, and in five short years, it had become a major player in the bike industry. It started producing other components such as bars, stems, and forks. 

In 2010, EDGE changed its name to ENVE Composites due to European trademark issues. Despite a great relationship with the European trademark holder, and the option for a licensing agreement, Schiers opted to let the trademark holder have the name. With business growing and a new state of the art facility in the works, EDGE transitioned into its final form and rebranded as ENVE.

ENVE M-serisThat same year, the year the Zipp 303 became the first carbon wheel to win Paris-Roubaix, ENVEs DH wheels became the first carbon wheels to win a World Cup Downhill race under Greg Minnaar. It proved to many doubters that carbon mountain bike wheels could deliver great strength and reliability at a lower weight. With its M-series wheels, ENVE has continued to innovate in the mountain bike space.

For road wheels, ENVE brought in aerodynamicist Simon Smart, a former Formula 1 engineer, to design the next generation of aero road wheels. ENVE’s SES wheel systems now compete with Zipp’s offerings and are shaped to be aerodynamically faster and more predictable in dynamic wind conditions by controlling airflow reattachment (more on that later).

Zipp discovered in the early 1990s that the key to good aerodynamics is minimizing air separation over the surface of a wheel and keeping airflow attached for longer. The easiest way to do this is to make the rim deeper. By doing this you effectively make the hole inside of the wheel smaller so the wheel slips through the air more easily.

Zipp aero wind tunnel testingFor Zipp’s road wheels, higher numbered model names indicate deeper section rims. Shallower rims will weigh less but are less aerodynamically efficient. In general, shallower rims are preferred for climbing due to their lighter weight. A deeper, more aerodynamic rim shines at higher speeds, usually on flat terrain.

The 202, 303, 404, and 808 rim models have remained in use through every generation of Zipp rim shape from Firecrest to NSW. The 303 model is the most popular as it strikes a nice compromise between aerodynamics and weight for all-around riding.

The 454 and 858 NSW wheels have two numbers listed for depth because of their Sawtooth rim architecture.

ABLC (Aerodynamic boundary layer control)

ABLC Zipp dimplesThe characteristic golf ball-like dimpling on the rim surface is a distinctive Zipp feature. A rim can only take advantage of the airflow if the air adheres to the rim surface. Airflow often becomes separated when a rim begins face airflow at an angle. This creates a vacuous region behind the rim, which causes “pressure drag.” According to Zipp, roughly 50% of real-world riding occurs with effective wind angles between 10 and 20 degrees.

ABLC dimples force the airflow into a higher energy state, forming a turbulent boundary layer near the surface of the rim, which allows the air to remain attached to the rim even at higher angles. This shifts the sweet spot of the rim into the ideal zone (10-20 degrees) while still reducing drag at other angles. The result is a wheel that is faster in a range of conditions.

ABLC dimples are patented to Zipp and it has developed its own special molding process in the U.S. to manufacture dimpled rims.

Firecrest rims

Zipp 404 firecrestZipp was one of the first to embrace the more efficient toroidal rim shape — a rounder and more blunted shape than traditional V-shaped aero rims. The Firecrest rim shape was introduced in 2010 with the new 404 Firecrest. It concentrated on aerodynamics at both the front and the back halves of the wheel. Zipp claims Firecrest was the first aero profile to effectively control airflow around the back half of the wheel. Firecrest is still in the Zipp lineup, second to the top-of-the-line NSW wheels.

404 Firestrike rims

In 2014 Zipp launched the limited edition 404 Firestrike wheelset. The new wheelset was slightly wider and offered a claimed 34% increase in crosswind stability compared to the 404 Firecrest. They also introduced a revised “Showstopper” brake track for improved braking in all weather conditions. Zipp produced 404 of the limited edition wheelsets, echoing the 404 model name.

NSW rims

Zipp 454 NSWNSW stands for “Nest Speed Weaponry” and is Zipp’s current top-of-the-line offering. “The Nest” is the nickname for Zipp’s advanced development lab where it creates its halo-level products. Zipp’s most radical design ideas can be seen on the 454 NSW and 856 NSW wheels which use the new Sawtooth rim shape. Using the principles of biomimicry, Zipp engineers studied how nature solved problems of speed, control, and efficiency.

The examples they point to are the shape of a humpback whale’s pectoral fins and the micro texture of a shark’s skin, which allow these animals to glide effortlessly through the water. These structures inspired Zipp engineers to apply these shapes to a wheel with patented fin-shaped “Hyperfoil” nodes along the inner diameter of the rim, which form the Sawtooth profile, and “HexFin” ABLC dimples that mimic shark skin. This design reduces more aerodynamic drag and side force.

Showstopper Brake Technology

Zipp showstopper brake trackCarbon rims have long had a reputation for poor braking performance compared to aluminum rims, especially in the wet. Zipp addresses this with the Showstopper brake track, which first appeared on the 404 Firestrike rim and has become standard on current rim brake NSW rims. It uses 317 directional grooves on each side of the wheel that increase stopping power and clear water from the braking surface. Zipp claims Showstopper delivers braking force equal to aluminum rims in wet conditions. The brake track is optimized for use with Zipp’s Tangente Platinum Pro Evo Brake Pads.

Cognition hubs

Zipp cognition hubWith the NSW generation of wheels, Zipp introduced its new Cognition hub for all NSW models. When a conventional hub is coasting, friction and drag within the freehub ratchet mechanism slow the rider down. Freehub drag can also contribute to chain-drop issues.

The rear Cognition hub solves these issues with “AxialClutch” technology. This reduces drag by completely disengaging the ratchet mechanism when coasting. It then uses magnets to re-engage it once the rider resumes pedaling.

The Cognition rear hub shell is also designed to distribute the hub flange load away from the bearings for smoother rolling bearings, regardless of spoke tension. The front hub has a unique scalloped edge hub shell design to prevent the growth of bearing bores when high radial spoke tension is applied. Zipp claims this all helps the bearings stay quieter, roll faster, last longer, and provide a laterally stiffer hub.

As noted previously with Zipp, the key to good aerodynamics is minimizing air separation over the surface of a wheel. The easiest way to do this is to make a wheel deeper.

For ENVE’s SES road wheels, higher numbered model names indicate deeper section rims. SES rims feature a different depth for front and rear rims as part of their SES aero design philosophy. The SES 3.4 model is the most popular as it strikes a nice compromise between aerodynamics and weight for all-round riding.

The width of all current ENVE SES wheels is aero optimized for 25mm tires except the AR models which are optimized for wider 28-32mm tires.

SES rims

ENVE SES rimsENVE introduced its new SES (Smart ENVE System) wheels in 2011. It brought on aerodynamicist Simon Smart to design, test, and validate its new wheels. Smart had 10 years of aerodynamics experience in Formula 1, and he had become a go-to consultant for cycling manufacturers. When wind-tunnel testing aero bikes for Scott and Giant, Smart started developing his own ideas for how to make the faster wheels after changing out multiple wheels during testing. He just needed a company to build them. ENVE was the ideal choice.

As discussed with Zipp’s ABLC dimples, airflow that detaches is turbulent and increases drag. When there’s no wind or the wind is head-on, the goal for an aero wheel is to slice through the air with minimal drag. As the wind angle (a.k.a. yaw) increases to create a crosswind, the drag of an aero wheel will stay low as long as airflow can stay attached. Modern aero rims are shaped to keep airflow attached for as long as possible, often beyond 15 degrees. The common thinking is that the more crosswind that a wheel can handle, the faster it will be. That’s partially true, but there’s more to it than that.

ENVE SES wheels rimsFor ENVE, the ultimate goal was speed on the road rather than in the tunnel. The difference is, the road is a “dynamic environment.” Even without gusts, the wind a rider encounters in the real world is constantly changing speed and direction. By contrast, accurate testing in a wind tunnel requires a static environment where the airspeed and direction are consistent.

In the real world, strong gusts and direction changes cause airflow to detach, and it doesn’t always reattach at the same angle at which it separated. This is called hysteresis and it can mean that the airflow remains stalled long after a gust has passed. For ENVE, the faster airflow can reattach to the rim, the faster a wheel will be. Rapid reattachment is the defining principle of the SES rim shape. To this end, ENVE has made the front and rear wheels different depths and widths to maximize each wheel's efficiency. The width and profile of SES rims have also been optimized for 25mm tires and they are tubeless compatible.

Rapid reattachment not only improves speed but stability and rideability too. This can contribute as much to performance as pure aerodynamics. A more stable and aerodynamic wheel that is as versatile as a shallower wheel on windy days can be invaluable. ENVE claims SES wheels feel like half their depth in the wind and are easy to handle.

AR rims

The all-road focused AR rims were a direct result of ENVE’s close partnership with Team Dimension Data. Before the cobbled classics in 2015, ENVE engineers attended a training camp and saw the team using 30mm tires to improve ride quality on rough cobbled roads.

For aero performance, rims need to have an external width that’s very close to the tire width to smooth airflow and keep it attached. Aero road wheels wide enough for 30mm tires were unheard of, but the introduction of disc brakes to road bikes finally made it possible. AR wheels were introduced to give riders and racers an SES aero option optimized for wide 28-32mm tires that work better on rough and mixed surfaces like cobbles and gravel. Colin Strickland (pictured above) used 42mm gravel tires on AR wheels to win the 2019 Dirty Kanza. 

Textured brake track

ENVE Textured brake trackCarbon rims have long had a reputation for poor braking performance compared to aluminum rims, especially in the wet. ENVE addresses this with the textured brake track found on the SES 2.2, SES 7.8, and the most recent versions of SES 3.4, and SES 4.5 wheels. ENVE claims this provides near equal wet and dry performance, better heat management, and 30% less lever force required for the same stopping power. ENVE recommends using its “black” carbon-specific brake pad designed for the textured surface.

Molded spoke holes

Look closely, and you’ll notice that, unlike most wheels, ENVE wheels don’t have visible spoke nipples. This is because ENVE chooses to use internal nipples that sit inside molded spoke and valve holes. ENVE molds rather than drills, because drilling in carbon fiber weakens that area and requires reinforcement with extra material. This adds weight and can compromise the carbon layup’s ride quality. Molded holes are more labor-intensive to manufacture but this patented feature is part of ENVE’s commitment to maximizing ride quality and durability.

Carbon Road Hub

Unlike Zipp wheels, ENVE provides multiple hub options from outside manufacturers (Zipp only uses Zipp-branded hubs). ENVE riders can use ENVE’s alloy hubs or choose to upgrade to hubs from Chris King and Industry Nine (older models also offered DT Swiss).

But riders looking for the ultimate ENVE hub option can also choose the lightweight ENVE Carbon Road Hub. The latest ENVE Carbon Road Hub builds upon the first generation carbon road hub’s legacy. The new hub shell geometry delivers 16% more lateral stiffness when compared to the first generation carbon hub shell. Additionally, the flanges of the hub have been completely redesigned to prevent premature spoke fatigue and feature a new spoke hole pattern that increases drive stiffness and reduces weight.

Low maintenance was a key objective, so the Carbon Road Hub drive system uses a DT Swiss-style, 40t ratchet. It uses high-grade custom stainless steel bearings and races to prevent corrosion in any condition or environment. 

Budget options

It’s no secret that carbon wheels are more expensive than aluminum wheels. If you want the pinnacle of carbon wheel technology, look no further than Zipp NSW or ENVE SES wheels. But the price is hard to swallow, Zipp and ENVE also offer more affordable carbon options, which will still be a noticeable improvement over stock aluminum wheels.

Zipp 302

Zipp 302 wheelsTo reduce cost, the 302 uses a smooth carbon rim that forgoes the patented ABLC dimpling used on higher-end Firecrest and NSW wheels but retains the 45mm deep toroidal rim shape. Zipp claims that depending on the conditions, yaw angle, and rider style, a dimpled 303 wheel will be on average two or three watts faster. The 302 also uses traditional hub flanges with J-bend spokes rather than the lighter and stiffer straight-pull flanges and spokes used on the Firecrest and NSW. This amounts to a 40-gram increase for the 302s compared to a set of 303 Firecrests.

Zipp 303 S

Zipp introduced the 303 S as the ideal wheel for riders who ride varied surfaces like rough pavement, cobbles, dirt, and gravel. It's designed specifically for tubeless disc-brake applications. The rim is 45mm deep with a wide 23mm internal rim width. Wide rims optimize tire profile to allow lower tire pressure, especially with tubeless. This increases the contact patch of the tire for increased grip and confidence when cornering, descending, and handling in wet conditions. the 303 s accommodates 28mm road tires all the up to 50mm gravel tires. 

ENVE Foundation 45 and Foundation 65

ENVE’s new Foundation Collection wheels were recently released as ENVE's first lower-cost alternative. There are two Foundation road wheelsets available (disc-brake-only) — the ENVE 45 and 65, which have 45mm and 65mm depths respectively. Price is reduced by using a single rim profile front and rear (remember SES uses a different rim profile for the front and rear). They are also built with a simplified version of ENVE’s alloy disc hub and cheaper spokes. Overall, they weigh only slightly more than an SES equivalent and sacrifice a tiny bit of aero efficiency for affordability.

Popularity

Because The Pro’s Closet is the world leader in used bikes and components, including wheels, we have substantial data about what brands sell well. I dug into our wheel sales for the last 12 months and compared how many Zipp wheels we sold compared to ENVE wheels. The two are among our top-selling high-end carbon wheels (alongside Reynolds) so sales can be fairly compared to determine popularity among our customers.

I also polled riders at The Pro's Closet to see which brand they preferred between the two. Our employees all love cycling, obsess over bikes, and have access to a huge selection of products. They are knowledgeable and opinionated. We had over 60 respondents to this poll and many explained why they would pick one over the other.

The charts below show the results.

Zipp vs ENVE wheelsIt is interesting to note that our sales figures reflect the opposite of what our poll results show. Among our customers, Zipp wheels sell twice as well as ENVEs.

Zipp enjoys a lot of popularity due to its great reputation as the benchmark for aero performance. This is clear when you look at things like the Kona Bike Count. The Ironman World Championship in Kona is the biggest event in triathlon and for nearly two decades, it’s shown us the buying patterns of elite triathletes. This is meaningful to us because elite triathletes have a reputation among cyclists for an interest in performance above all else. If they’re using something, it’s because it’s been shown to work in the lab or through real-world performances. At Kona, Zipp has long been the dominant wheel choice. In 2019 it was no different with 1,596 out of 2,377 competitors using Zipp wheels. ENVE trailed behind in second with 460 competitors.

Does that mean ENVE is technologically inferior? Not at all! Keep in mind that Zipp had 15 years to establish itself in the cycling world before ENVE existed. Over the next 15 years, ENVE did a lot of catching up to reach where they are with their SES wheels. In time, the tides might shift if more riders perform well and win on ENVE products.

Looking at the sales, it’s also important to consider that mountain bike wheels make up nearly half of ENVE wheel sales at The Pro’s Closet, but only road wheels are accounted for in the sales data. For years, ENVE has made some of the most sought after mountain bike wheels on the market. Zipp only just released its 3Zero Moto mountain bike wheels in 2019. It will take time to catch up in a new genre.

Why is ENVE more popular with our riders? A lot of our younger riders seemed to prefer ENVE simply due to their aesthetic preferences. Many cited the beautiful looking logo as a reason enough to choose ENVE. Several liked that ENVE wheels had more hub options from hub specialists like Chris King, Industry Nine, and DT Swiss. Another thing to note is that many ENVE fans were also mountain bikers who were already familiar with ENVE’s mountain bike offerings.

Interestingly, it seems that many older riders (35+) at The Pro's Closet were more interested in Zipp. A couple of our former pros and industry veterans cited Zipp’s history and reputation as major factors in their decision.

Final thoughts

Zipps and ENVEs are the rare type of product I always notice when they come through the shop. Literally any bike that comes in with a pair of Zipps or ENVEs instantly earns some degree of respect. This is even more true for me if the bike’s frame is a complete beater. If I had to choose between a high-end frame and high-end wheels, I would choose wheels all day, every day. Wheels are that important to how a bike performs.

With all the technology they pack in, it’s clear that both Zipp and ENVE wheels would be a serious upgrade for any cyclist, especially those coming from stock aluminum wheels. What would I pick? I'd honestly be happy with either. But force me to choose and, right now, I’d probably jump on a pair of Zipp 454 NSW wheels for my personal bike. Why? Just look at them. They’re insane. The eye-catching Sawtooth rim profile, the intense dimpling, and the magnetic Cognition hubs all make the nerd inside me squeal with delight.

Kent Erikson ENVE bikeI've had a few bikes with ENVE wheels. They just look good. 

Saying this now is actually a surprise to me. For the longest time, I’ve loved ENVE for its aesthetics. The wheels are simply beautiful. The name, the big palindrome logos, and the beautiful carbon layup give their products an unmatched aura of refinement. In the past, I’ve used ENVE wheels on three of my own personal bikes and been extremely happy. I would use them again, but maybe I’m just looking for a change.

  • Wouldn’t TPC wheel sales be correlated with how many people sell their wheels to TPC? If less people are selling their ENVE wheels to TPC, wouldn’t ENVE sales automatically be lower?

  • I just upgraded from a set of HED Ardennes CLs to the Enve 2.2’s with DT Swiss hubs 54T.
    I have always been a fan of Enve, beautiful design, now that I’m on the 2.2s I find them to be light, responsive and stiff. I can certainly tell the difference between my HEDs night and day. Although ZIPP makes incredible wheels and are very popular especially in Southern CA, I wanted to go with the new kid on the block, Enve! I suppose one could use the analogy of being either a Ford Mustang lover or Chevy Camero, I’m a Chevy guy and Love my Enves!!

  • As a Clydesdale, the molded spoke holes of the Enve wheels make all the difference. I’ve got 25,000mi on a 3.5 configuration and put some new decals on and they look new, with only a slight sheen on the textured brake tracks. They still stop like the new ones on the other bike. I use Sapim Force spokes and they look new too. Tough as nails.

  • I’m running ultra light carbon wheels ( aftermarket) didn’t know that at time of purchase. But with extradite hubs. Tubular
    I had a serious crash and cracked the front wheel. So my question is , would you replace both wheels and go with Zipps? Which model ?
    Should I stay with tubulars? I’ve have many problems mostly cracked nipples …
    I ride a Wilier Zero 7 , so it’s a high end bike … you get the idea. Need some advice

    MIchael Famiglietti on

  • Guf, what a thorough explanation, I loved the attention to history and detail.
    Hhmmm, I own a pair of 303 (2018), they are great wheels, and you do notice the advantage over shallow alum ones, once they start they just roll. But, sometimes they seem not that stiff (I’m not light…), and I’ve heard that ENVE wheels are stiffer and better for bigger riders (80 plus kg), could this be true?
    Another thing, how about durability, not about bearings and hubs, talking about the carbon rim.
    I cracked a little part of the front wheel and had it repaired (5.000kms and going strong), in a not-that-big of a pothole, how is the experience and technical data in that respect?

    Thanks again

    Galgo on
