Why you should ride an endurance road bike

By Bruce Lin


We’ve all probably heard the motto “no pain no gain.” In sports and exercise, there is a belief that suffering and sacrifice are necessary to achieve your goals. Sure, you have to work your legs and lungs hard to get fitter and faster. But there's no reason your bike needs to be harsh or uncomfortable. 

This is where endurance road bikes come in. Over the last 15 years, endurance bikes have developed into a new category separate from traditional road racing bikes. Their primary goal is to provide more comfort, especially over rough road surfaces and long-distance rides.

endurance road bikesWhen shopping for new or used road bikes, many riders are drawn to the low and aggressive look of racier bikes — bikes similar to what the professionals are riding. But chances are, you aren’t a professional cyclist. If you’re an average rider (like me), do you really need a pro-level road racing bike? What type of bike will give you the ride experience you’re really looking for? I would bet money that most riders would be better served by a comfortable and relaxed endurance bike than a stiff race bike.

This piece will cover the major differences between road race bikes and endurance bikes. It will explain why endurance bikes are a great choice for regular riders looking to enjoy their time on the bike. Hopefully, armed with this knowledge, you can make a better decision about what type of bike is right for you.

If you want to learn more about the terminology and tech behind road bikes, check out our comprehensive Road Bike Buyer’s Guide.

What is an endurance bike?

Endurance bike dirt roadsDirt roads won't stop an endurance bike. 

An endurance bike is a more versatile road bike. It can race, take on gran fondos, jump in fast group rides, and grind out your daily commute. It can even venture away from smooth pavement and comfortably explore rough roads and even some dirt and gravel. It isn’t as laser-focused as a race bike, allowing it to cover a much wider range of riding conditions.

Most major road bike manufacturers produce both dedicated road racing bikes and endurance road bikes. Some also make aero road bikes or dirt-focused gravel bikes to cover the full spectrum of drop-bar riding. The table below gives examples for each style of bike offered by some of our most popular brands:

For this article, we'll focus on the endurance column. The Roubaix, Domane, and Synapse are among our top-selling bikes.

In general, all endurance bikes will share three key traits: 

  • More relaxed and stable geometry
  • More tire clearance
  • More frame compliance

Bike GeometryRelaxed geometry means endurance bikes have a higher stack, lower bottom brackets, and longer wheelbases than road race bikes (read our article on how bike geometry works to learn more about these terms). This provides a more upright riding position that can increase comfort. It helps relieve pressure on your hands and sensitive organs in the saddle area and it reduces strain to the lower back, shoulders, and neck.

The low bottom bracket and longer wheelbase help make endurance bikes more stable. Endurance bikes won’t have a darty feel like many road race bikes. They are still agile, but because modern endurance bikes favor stability, they provide a more relaxed ride. Less energy needs to be dedicated to controlling the bike, meaning you stay fresher and more comfortable during long-distance adventures.

Because of the relaxed and stable geometry, they’ll also stay more composed over rough and uneven surfaces. This is why many professionals choose endurance bikes for tough spring classics like Paris-Roubaix.

“Last year, [the EF Pro Cycling team] pretty much all ran the Synapse at Paris-Roubaix,” explains Chad Moore, global marketing manager for road and urban at Cannondale. “The main reason is the extra comfort and stability. You need it in such a brutal race, especially over the cobbles. The second main reason is the ability to fit a bigger tire.”

Tire clearance

Endurance bike big tire clearanceAn endurance bike needs to clear at least 28mm tires like these Hutchinson Sector 28 tubeless tires. Photo courtesy ENVE Composites. 

Proper endurance bikes can fit at least a 28mm wide tire. All current endurance models listed in the above table are capable of fitting much wider 32-35mm tires. The Trek Domane can even fit massive 38mm tires. Larger tires are the best way to improve comfort. The extra air volume of a larger tire provides more damping and traction on imperfect road surfaces, dirt, gravel. They absorb bumps so your body doesn't have to.

“Modern endurance road bikes are becoming way more versatile in terms of tire widths that they can fit,” says Moore. “They’re way more comfortable and capable now because of these wider tires. With 32s they can handle way rougher roads and dirt.”

For riders accustomed to fast 23-25mm tires on road racing bikes, the major downside of wider tires is increased rolling resistance. But with new tire technology and especially tubeless road tires, the difference in rolling resistance is shrinking.

“Tests are showing that modern, wider tires have lower rolling resistance than they used to,” explains Moore. “If you run them at the right pressure they’re really not much slower than the 25mm tires most race bikes run but they are much, much, more comfortable.”


Greater stiffness is an often touted benefit of high-end road racing bikes. More stiffness means less energy is lost to the frame flexing while pedaling. But this race-ready stiffness can also lead to a punishing ride. Wider tires can do a lot to alleviate this, but modern endurance bikes also have more compliance built into the frame itself. A good example is Cannondale’s SAVE (Synapse Active Vibration Elimination) Micro-Suspension design used on its Synapse endurance bike.

“It has to do with the carbon lay-up and how the frame reacts to input,” explains Moore. “More vertical flex is built into key areas to reduce the shock and vibration you feel out on the road. But it’s still stiff laterally so, even though it’s comfortable, you don’t lose much of the pedaling efficiency you want in a road bike. It’s a concept that we also use on SAVE components like the handlebars and seatpost. It works as a whole ecosystem, increasing compliance and comfort while still pedaling well."

Most manufacturers use designs similar to this, with carbon layups that increase vertical flex in key areas like the seat stays and fork. If you look closely at endurance road bikes released in recent years, you’ll notice that many use a dropped seat stay design. Dropped seat stays join the seat tube below where the top tube joins. This creates a structure that flexes more easily. Despite all this added flex, enough lateral stiffness is maintained to still pedal efficiently.Specialized Roubaix comfort

The Specialized Roubaix uses dropped seat stays in the rear and Futureshock in the front to increase comfort. 

Popular endurance bikes like the Specialized Roubaix and the Trek Domane employ unique technology to further maximize rider comfort. Specialized’s Futureshock adds a coil spring suspension element under the stem to absorb impacts. Stiffness can be adjusted for the terrain or your comfort needs. Trek’s IsoSpeed technology decouples vertical parts of the frame like the seat tube and fork steerer from the rest of the frame using pivots and bushings. This decoupling helps further deaden vibration and impacts. If you’re interested in learning more, these technologies have been explored in more detail in our Roubaix vs. Domane comparison article.

While the extra technology in the Roubaix and Domane can improve comfort, most modern endurance bikes are extremely comfortable already thanks to big tires and frame compliance. Some find the added features of the Roubaix and Domane to be essential. Others may find it needlessly complicated. Though obviously biased as a Cannondale representative, I asked Chad Moore about it and he fell into the latter camp.

“Bigger tires with lower pressure make the most difference and it's even more effective when coupled with the frame and component design,” he says. “If it works for you then great, but I think you can design compliance and achieve great comfort without adding that level of complexity to the bike.”

Why should you ride an endurance bike?

For the average rider, increasing comfort can improve your speed more than aerodynamics, weight, or stiffness. Last year I interviewed bike fit guru, Andy Pruitt, (read the full article here) who has worked extensively with some of the world’s best pro riders and teams. In his experience, a less aggressive and more comfortable riding position was beneficial to both highly experienced and novice riders.

“Comfort helps you go faster,” Pruitt explains. “If you’re more comfortable you’re going to be able to go faster and harder for longer, rather than fighting to stay in some aerodynamic position.”

Some of the engineers who design bikes agree. 

“Every minute you can stay in your position will save you more time than a fancy tube shape,” says Wolfgang Kohl, Product Engineer at Canyon. Kohl is one of the engineering minds behind the race-winning Canyon Speedmax aero road bike, so he knows a thing or two about going fast.

“If you want to keep yourself fit and try to get some PRs or KOMs on Strava, you don’t need a super aero bike!” Kohl says. “Aero is sometimes overrated on the magazine or customer side. For most people, a comfortable bike that allows you to stay in a good position will keep you fresh for rides that are three hours or longer. That is a much better riding experience than doing the same ride on a super-aero bike with an aggressive position and tube shapes that do not flex.”

Endurance bike long distance adventuresPruitt also makes the point that a more comfortable bike will be a bike that you’re more likely to ride. The whole point of having a bike is to ride it and enjoy it, right? A racing bike that hurts your body and can’t be ridden for more than an hour or over long distances can detract from the experience of cycling.

“The riding experience should be the main reason a cyclist buys an endurance bike,” says Chad Moore. “The experience is the focus. With endurance bikes, we're not as concerned about going blazingly fast all the time, and we're not worried about saving five watts because the down tube is the right shape.”

Endurance bike corneringBut don't assume that endurance bikes aren’t aerodynamic or fast. Modern endurance bikes are still designed for performance. 

“Prioritizing comfort doesn't mean that we don't think about speed during the design process, or that we don't wind tunnel test to benchmark a bike against competitors,” says Moore. “It just doesn't dictate the design of the bike as much. With an endurance bike, we're not going to compromise its key comfort traits to make it a tiny bit more aero or lighter. But the gap between road race bikes and endurance bikes is getting a lot smaller. That's a trend that we're seeing. And I'm anticipating in the future, you'll start to see a more condensed range of road race bikes form all brands — a bigger focus on what we now call endurance bikes.”

“The majority of riders should try to have more fun on their bikes,” says Kohl. “It’s good to have the freedom to choose a riding position that fits your body. A lot of us don’t have a lot of time to do stretching and core stability every day or have a physiotherapist like the pros. We’re office workers, craftsmen, or mothers, we have full-time jobs and ride bikes to stay fit and have a good time with our friends. To do that you have to have a bike that fits and gives you comfort. For a lucky few this might be an aggressive aero race bike. But it’s more likely an endurance bike.”

Who should ride a road race bike?

Knowing everything that’s been laid out above, is there still a reason to choose a road racing bike over an endurance bike? Well, of course, if you simply like the looks or feel of a true road racing bike, don’t let me stop you! Having a bike you love is key. If that must be a race bike, then you probably won't mind sacrificing some comfort to satisfy your desires. 

If you’re a competitive rider who loves racing and fast group rides, then the marginal gains of better aerodynamics or more stiffness could be worthwhile.

If you’re a fit rider who can easily handle a lower and more aggressive riding position and a stiffer ride, then you may not need the extra comfort an endurance bike offers.

If your local roads are smooth as glass and you rarely venture onto bumpy, rough roads, then the extra tire clearance and compliance of an endurance bike might be unnecessary. 

What about gravel bikes?

If the relaxed geometry, extra tire clearance, and compliance of an endurance bike is good, then why not take it further and get a gravel bike? Gravel bikes have even more relaxed geometry and are designed to fit massive 38-45mm tires. They are made to keep riders comfortable on rough and loose surfaces, which means you'll be just fine on smooth surfaces too. This may be a good idea for some riders. But keep in mind what type of riding and terrain you actually need your bike for. When should you choose a gravel bike over an endurance bike?

“So we generally don’t talk about a road race bike being versatile enough to ride on dirt roads,” says Chad Moore. “Likewise we're not going to use the word ‘gravel’ when we talk about endurance bikes. For an endurance bike like the Synapse, we would talk about ‘all roads’ and ‘dirt roads’ but we don’t go very far beyond that. The rider that's getting an endurance bike, is not really going to be riding the type of technical gravel and trails that dedicated gravel bikes are designed for.”

If you’re a road rider looking to explore dirty terrain beyond the pavement, can you still ride an endurance bike on gravel?

“Sure,” says Moore. “Before gravel bikes, plenty of us hit Switzerland Trail (a local four-wheel-drive trail) on skinny tires. I’ve ridden single track on 28mm tires. You could squeeze 33, maybe even 35mm tires on an endurance bike like the Synapse and ride on whatever terrain you want. For most, the limitations are going to come with the rider before it comes with the bike. But I'd say once you start hitting singletrack or gravel with chunky or loose surfaces, doing it on a dedicated gravel bike is much nicer.”

Riders who spend the majority of their time on pavement or smooth dirt will still be better served by an endurance bike. The bike will be lighter and more efficient with more moderately sized tires. Gravel bikes work great on pavement, but their geometry often makes them feel more sluggish compared to dedicated road bikes.

“Gravel frames change so much to fit a big 40-45mm tire or a 2.1” 650b tire,” explains Moore. “You need super long chainstays to clear tires in that size range and that slows down the handling some. You end up with a bike that's purpose-built for really aggressive gravel and erratic terrain. They can feel good on the road but they really come alive on more aggressive gravel.”

Final thoughts

I have owned plenty of extreme bikes. Throughout my 20s I purchased aggressive road racing bikes because I wanted to emulate the pros I watched on TV. These bikes were incredibly stiff and had low, stretched out positions. When I was young, a little numbness or lower-back pain didn’t bother me. I just dealt with it. 

Retul bike fitAfter years of pain I had to leave the low, aggressive race bikes behind.

Now that I’m older and I’ve lost a lot of flexibility and suffered several injuries, I find the low race positions tend to exacerbate issues with my hands, shoulders, and back. My fitter suggested adopting a much more relaxed riding position. As a result, I’ve transitioned to riding more relaxed bikes. After a few years riding a Specialized Roubaix, a Trek Domane, and a Cannondale Synapse I don’t think I’ll go back to a more aggressive bike.

All this being said, it is possible to feel comfortable on a race bike with a proper bike fit. It’s also possible to feel uncomfortable on a bike designed to be comfortable if your fit is off. Whatever bike you choose, getting professionally fit is always a good idea. (Read about my experience getting a professional Retül bike fit here.)

These days, I ride my bike to stay fit and enjoy the outdoors. Endurance bikes help me do that while still being quick enough to attack Strava segments and hang on fast group rides. 

In the last year, I purchased a gravel bike as my one drop-bar bike with a slick wheel and tire set-up for pavement. This bike works great on the road, but I do find myself hungering for the agility and lightweight feel of my old endurance bikes. Next year, you’ll likely find a new endurance bike in my garage. For me, it’s the perfect middle ground, do-it-all road bike.

Do you ride an endurance road bike? Or is there a different option that works better for you? Let us know in the comments!


  • Endurance bikes are 2.5% slower than road bikes on flat roads, on a 5% grade climb endurance bikes are slower by 2.7%, when the speed increases over 40km the endurance bike can be 5.25% slower. This means that the difference is in aerodynamics.

  • This is exactly the article I needed. After laboring for a while about which bike to get, I’m convinced to take your advice. I agree with Bruno – the chart alone was very helpful (we need similar charts for components). Despite having done tons of my own research, it helped me narrow my focus on just those models. With that said, the racing bikes just look so cool. I guess the best finish designers only want to work on the fastest, hi-tech bikes. Am I to customize a brand new, $4k+ endurance bike? Hmmm 🤔

  • A very detailed explanation on why the endurance bikes is an all round option. I own a Scott Speedster and was “wanting” to upgrade to Trek Madone but after reading this article I will give Domane SL 6 a second thought. Thanks mate.

    Raj Sharma on

  • This article has definitely caused me to pump the breaks on my next purchase. I was getting all hot after riding a Trek Madone SL7, and while I like the Domane (I also ride a 2013 Specialized Spectre), I was being pulled by sales to the Madone….But, I’m wanting to ride more and longer…and I’m not 100% sure I should get a Madone if 1. I’m never going pro, not even close 2. an Endurance Bike could be potentially “just as good”.

    Ryan Milton on

  • One of the simplest to read articles on endurance bikes. Kudos! I have recently got my myself a endurance bike (Trek Domane SL4) and am hooked

    Indrajit on

  • I ride a Trek Checkpoint AL 3 gravel bike, went and got fitted recently because I was having knee pain due to switching from clipless to flats. Great bike, definitely can be a bit sluggish on hills, but as this is my first season of actual road riding, it’s serving me well as an endurance. My eye is on a Domane for a future upgrade, but not until I can increase my base endurance, get better at shifting to match cadence and anticipate my shifts better. Also my performance with flats is on par with my performance on clipless. Not looking to race, just ride.

  • Thanks for the very informative article.

    Silas Carmo on

  • Great article indeed..After reading this, I’m so happy I have a changed of heart of not selling my endurance bike which I bought from you guys 2 years ago. I will probably keep it for a long, long time.

    fred on

  • Good article. I am an older guy who rides long Endurace events once a year. I was looking for something in between a race and Endurace geomentry, with the aim of being comfortable but a bit quicker with slightly lower body position. This article gave me a reality check; I am not a pro racer, and I am not a flexible person. Also, modern Endurance bikes cater for both comfort and performance. easy decision. I’m going for a Canyon Endurace CF SL 8.0 Disc

  • Hey Mark,
    Thanks for the question. Cross bikes haven’t changed much in the last couple of decades. You pretty much nailed the key geometry difference – BB height. They’re higher off the ground (and might have slightly steeper angles) so they’re agile and pedalable in the tight, bumpy, muddy, flat corners you find on cyclocross racecourses. Plus they’ll usually have a level top tube for shouldering. They’re really focused on the specific needs of cross racing. Endurance and gravel bikes, on the other hand, have lower BBs to maximize comfort and stability. On a cross course, a cross bike would be faster. For everything else though, endurance and gravel bikes are often easier to ride. 

    Bruce Lin on

  • I have sort of a cyclocross bike from 2014. Not as specialized as the cross bikes of today, but it still has a different geometry, e.g. higher bottom bracket clearance. I wonder how it and modern cross bikes compare to endurance bikes? btw really good article.

    Mark Shepard on

  • Wow! Very well written and concise analysis that helped me with my decision. As a newbie to road bikes, I was lost in shopping and needed guidance. This article shined a bright light on the type of bike that fits my needs. Thank you immensely!

    Frank from NY on

  • Awesome, thank you, I’m looking at a Synapse in the morning and had no clue…it sounds perfect, I have only ridden older steel frame road bikes (which I still love) but did once have a Cannodale Caad twenty years ago, which I loved and miss….I think I’m going to be a happy camper:)))). Thank you for the good advice:)!

    David Haughton on

  • This is a good read. I’m currently using Scott Speedster and never regret purchasing it since I’m not flexible and on a tight budget to invest in an aero roadbike.

    Hau on

  • Read this article having just pulled the trigger this morning on my first endurance bike (BMC Roadmachine01). All my road riding has been on race geometry bikes so I am excited to see how it stacks up (excuse the pun), including on strava segments, against a light race bike with enve tubs and rim brakes. Will let you know.

    David Knight on

  • I just upgraded from a 23 year-old Bianchi Campione to a Roubaix Pro (should receive it this weekend). At my age (61) I’m glad this article supports what I need in a bike to enjoy another 15 or more years of riding. I probably should have found this article before I spent $6k on a bike, but fortunately I picked the correct bike in the Specialized line (for me)!

    Steve Cirica on

  • Thanks for the very informative article. Exactly what I needed at this time. I have been riding a Trek Madone 6.9 carbon for the last 12 years. As I’ve aged and become a bit less flexible (as you pointed out) I am on the hunt for a new bike. At the moment, I’m between the Trek Damone, Trek Sport FX6, or perhaps a titanium bike.

    Tom on

  • Excellent article! Thank you for the detailed explanation. After cycling for the past 2 years or so on a bike my son purchased for himself, I am ready for an upgrade. When you’re fairly new to something it’s easy to make costly mistakes if you don’t have a reliable source to explain the matter in detail. I spent a lot of money on stuff I didn’t understand when I started hiking. Don’t want to make that mistake with a bike I wouldn’t enjoy riding so thank you for spending the time to write this – your article just reassured me in the decision to go endurance.

    Izabela on

  • I echo the comments of appreciation for the pragmatism in this article. I actually read the whole thing (historically I can only bear to scan most reviews). More folks would be on bikes if there was more clarity and less hype.
    I like my Cannondale Synapse Carbon Disc Ultegra very much but I know that the frame flexibility has been designed for the physique and weight distribution of a male body and so could be improved for a female like myself. I’d love to see a female-specific review of frames here. Thanks for considering.

    Paz on

  • Thanks Bruce for the clear, intelligent and useful description and comparisons of endurance bikes. One aspect of rider relation you alluded to but did not emphasize is “EGO”! It’s typically a male thing that prevents us from using our brains. Thanks for reminding me it’s OK to be sensible, smart, efficient and wise!

  • Great information. Excellent article in terms of explanation, accuracy and simplicity. Now I can conclude what bicycle type better fits for my actual conditions and goals. The included chart with the brands and models is very helpful.

  • Very good read. I have a 2013 Cannondale Carbon Synapse. I love this bike but time become more current but will stay with an endurance bike and maybe add the Gravel bike too :)
