Dream Build: The ultimate enduro bike

For the gnarliest downhills, you need the best enduro MTB. I picked Fox suspension, SRAM Eagle AXS, and Santa Cruz Reserve carbon wheels so this Specialized Enduro can take on anything.

Specialized Enduro dream bike buildMountain bike technology progresses so rapidly that bikes seem outdated in only a few years. Is there anything wrong with riding an older mountain bike? Heck no! But for a geeky gear addict like me, a biennial mountain bike refresh is a luxury. Even if updating my rig doesn’t actually make me faster, just having a new and improved machine enhances the joy of riding. 

Last month, I put together a dream titanium road bike to last “forever.” Now, I’m headed into the gnar with a dream enduro bike build. This is what I came up with.

Frame 

2021 Specialized Enduro Frame2021 Specialized Enduro - $2,299.99

I’ve improved my descending skills, explored downhill bike parks, and tried my hand at enduro racing. As a result, my hunger for big travel and progressive geometry is insatiable. The 170mm, ultra-slack (63.9° head angle) Specialized Enduro has been at the top of my wish list, and lucky for me, a beautiful, lightly used, gloss gray frame appeared in our inventory. It has a tunable Fox Float X2 shock that will easily handle the gnarliest trails that I dare ride.  

Fork

2021 Fox 36 fork2021 Fox Factory 36 150mm - $949.99
2021 Fox 36 170mm Air Shaft - $50.00

This might surprise some of you, but I’m going with the lighter Fox 36 instead of the burlier Fox 38. To ride the good stuff I have to haul my bloated carcass up some steep climbs. I’ll appreciate the ~200 grams it saves. I’m probably not aggressive enough to need the 38’s extra stiffness anyway. The 2021+ 36 has air bleeders and a stiffer arch, but I will have to swap the air shaft to convert it to 170mm.

Wheels & tires

Santa Cruz Reserve 27 carbon wheelsSanta Cruz Reserve 27 w/ Chris King Hubs - $1,899.99
Maxxis Assegai EXO+ - $85.00
Maxxis Aggressor DoubleDown - $81.22
CushCore Pro Tire Insert Set - $149.99

I picked Reserve 27 wheels because they have excellent ride quality, nice subtle branding, and I just can’t resist the bourbon Chris King hubs. Usually, I’d go for the wider Reserve 30s, but the 27s are what we have in stock. I think I’ll be fine since multi-time downhill world champion Loic Bruni still rides 25mm rims! For rubber, I always trust Maxxis tires and then add extra rim and puncture protection with a set of CushCore Pro tire inserts.

Drivetrain

SRAM X01 Eagle AXSSRAM Eagle AXS Controller - $159.99
Sram X01 Eagle AXS Rear Derailleur - $499.99
SRAM X01 XG-1295 10-52t Cassette - 384.99
Truvativ Descendant Carbon Crankset - $199.99
SRAM GXP Bottom Bracket - $32.99
SRAM XX1 Eagle Rainbow Chain - $85.00

I’m an electronic drivetrain convert and I think it’s time to put one on my mountain bike. The SRAM X01 Eagle AXS rear derailleur uses the Overload clutch, which will come in handy when I eventually crash. I’m also excited about the two extra teeth on the 10-52t cassette since I need all the climbing help I can get. To save a bit of money I went with an older Truvativ Descendant Carbon GXP crank.

Brakes

SRAM Code RSCSRAM Code RSC Right - $244.99
SRAM Code RSC Left - $244.99
SRAM Centerline X Disc Brake Rotor - $66.99 (x2)

I’m a big fan of Code brakes for their power and modulation. In general, I prefer SRAM brakes because they make it super easy to run my “backward” brake set-up. I’ll match them with a pair of two-piece Centerline X rotors, mainly because they look cool, but they also save a few grams too.

Cockpit

ENVE M7 handlebarsENVE M7 MTN Handlebar - $169.99
ENVE Alloy Stem 35mm - $124.99
Race Face Getta 33mm Grips Black/Gold - $22.99
Bike Yoke Revive Max Dropper Seatpost 185mm - $199.99
Wolf Tooth Remote - $69.99
Fizik Gravita Alpaca X5 Saddle + Carriage Kit - $119.99

I’m going with a classy ENVE handlebar and stem combo paired with the tacky (feeling) Race Face Getta grip. I chose the Bike Yoke Revive because it uses an open bath design with a reset function that makes it the smoothest and most reliable dropper post I’ve ever used. That’ll be topped with a downhill-specific Fizik Gravita Alpaca saddle that has a nifty integrated tool kit.

Total cost: $8,211.03

You can buy some very nice mountain bikes for over eight grand. But for me, it’s satisfying to pick the ideal components and build a bike from the frame up. This Specialized Enduro can act as an everyday trail bike while still being capable of shredding every downhill track within driving distance. I expect the carbon wheels to be the biggest source of contention. Knock on wood, but my fat butt hasn’t broken a wheel since I started using CushCore so I have a lot of confidence in this setup. 

Did I make good choices? What would you do differently? Let us know in the comments!
