It’s been a while since we’ve posted one of Fair Wheel Bike’s custom builds. But this crazy light Specialized Epic EVO proves that they’re still cranking out some incredible bikes in Arizona. Jason Woznick of Fair Wheel tells us that this bike was created not to make the absolute lightest bike possible, but to better fit the needs of the rider who happens to be around 100lbs. Not only that, but they manged to come up with a final build that is about two pounds lighter than the stock S-Works Epic EVO, but for less money. Impressive.

It should be noted that the 19.8lb weight is for a bike with 120mm of travel front and 110mm rear, a 125mm travel dropper post, and even a remote fork lockout.

Carbon-Ti X-Rotors rely on stainless steel for the braking surface, but drop some weight with carbon fiber carriers and titanium rivets. The rotors are combined with Shimano XTR dual piston brakes.

The drivetrain is also basically stock Shimano XTR 1×12 with the exception of the e*thirteen XCX Race 170mm crankset with UL 30t chainring.

The wheelset is pretty exotic with FSE carbon rims, Extralite Hyperboost hubs, and Pillar Xtra Ti AL nipples, but the thru axles are stock Rock Shox and Specialized. Overall, it just highlights how light the new Epic and Epic EVO platforms are when you can build a full suspension bike with a dropper post and real tires that’s under 20lbs and still have weight to spare.

Update: Fair Wheel tells us that the build came in somewhere under $10,500 or about 10% less than the stock S-Works Epic EVO.

  1. Great profile of a sweet, hand-picked parts build, but I don’t see prices for how much this build was compared to an S-works? A price comparison would be great.

    • It would be tough to understand. Chances are, FWB didn’t charge this customer straight keystone retail for the parts. Likewise, an S-works broken down to retail component cost wouldn’t likely come in at the retail price they sell the bike for. I wonder if they made any money on this after it was all said & done.

  2. Neat, even though my FS MTB is slightly lighter, it has less gear range, no dropper and narrower tires. Lightweight frame really makes the difference, good for FWB.

  3. And how exactly do carbon-ti rotors “better fit the needs of a 100 pound rider?” That’s just a case of more money than common sense.

    • My guess is the likely ‘need’ was to have a full shnick-shnock build. If you have the dollars, you can make your own justifications. (My 4 year old, 24lb hardtail tells me I can’t have that justification, but I applaud anyone who can.)

    • Being a very light rider myself I can tell you bike weight makes a big difference for us small riders. Lighter rotors = Lighter bike = more suited to a light rider. But the carbon ti still have a fair amount of brake surface unlike some of the other superlight rotors which should mean better braking and better heat control comparatively. I think this bike looks perfect for a light rider, I’d love to own it.

    • A 100lb rider doesn’t need nearly as much stopping power as a 210lb rider like me does. They don’t have to worry about overheating the brakes either, so they can go for some parts that I would consider too scary and get a lighter bike out of it. It’s their money.

    • Rockshox sells the same eye-to-eye length SID Luxe just with a 5mm longer stroke strength. I swapped mine out and it works perfectly with tons of clearance still at bottom out. Comes out to about 123mm rear travel.

      Plus it comes with remote lockout so after swapping fork dampers I‘m now able to run front/rear lockout on a single remote. So it instantly becomes a 120mm race weapon that weighs less than any other 100mm option out there. Win-win

  4. I’ve heard it said a few times in recent years that a custom parts bike build is often the same price as, or sometimes less than, the roughly equivalent parts stock bike. This is for the high end price range only, say $8,000 and up stock bikes. Thoughts or comments anyone?

    • The refrain around our shop is that, with so many amazing options out there an S-Works purchase suggests a certain lack of imagination. Maybe a little harsh, but this sort of tailored build is a great example of what can be done for less money.

    • Generally true. I seem to remember being able to build up some identically-specced Santa Cruz bikes for less than retail while purchasing the parts at MSRP.

  5. So the frame and shock are around 3.8 lbs? If so, that’s pretty light. I’d like to see what other frames are close( or lighter) than this frame.
    I’d love to build a light 120mm-130mm XC/trail bike, but I ride a large and would expect a few more pounds added on than this bike.

    • Pretty sure the Epic is the lightest out there at the moment. It’s only 110mm rear travel though – think that was a typo in the article. As for actual weights, Pinkbike just did a comparison test and their large SWORKS was under 22 lbs.

  7. In particular is “less money than the S-Works” how much they sold it to the customer for?
    Or just how much they spent on the parts?

  8. I just had to laugh at the ‘rider who happens to be about 100lbs’. I haven’t weighed that since about 1979 on my last year of high school and no body fat. …And for those of us in the 150-200lb, normal peoples build?

  9. They are missing a few parts in the part list that are shown in the picture. 1) rear shock, 2) stan’s milk for a tubeless set up 3)pedals. Those will take it over 20lbs. In addition there are a few parts which can never be as light as they say in the list above:
    1) Two thru axles for 17g total ???
    2) Grips for 21g?
    3) headset (which presumably includes topcap and bolt) for only 48g??
    4) seat collar at 13g?

    But it’s still a nice bike. Price $5000.

  10. I have been riding nearly 60 years , now front drive feet first . I like some weight in motion for stability & coasting. with enough flywheel effect the bike stays upright better too.
