Custom Felt F1x Cyclocross/Gravel/Adventure Bike

We just did a custom road bike build that’s too cool and sexy not to share. It’s a Felt F1x cyclocross frame built up to be an all-around adventure bike with an emphasis on dirt. The proud owner, local cyclist Jay Miles, is primarily a mountain biker but wanted a bike he could train on year-round that would still be capable, comfortable and fun on the dirt. The custom Felt F1x is also his secret weapon for the 2018 Crusher in the Tushar, a brutal 70 mile point-to-point gravel/road race in Southern Utah’s Tushar Mountains with over 10,000 feet of climbing and 6000 feet of descent, including a 4000 foot switch-backed, washboard gravel road downhill. There’s no doubt the F1x is going to be a whole lot faster than the mountain bikes he competed on for the past few years.

The F1x is the flagship model for Felt’s FX Series cyclocross bike line. The Felt F1x was created and engineered to win World Cup cyclocross races. It’s the same frame that UCI World Champion cyclocross racer Wout Van Aert races on. It’s a serious race bike and an interesting choice for what, at least on the surface, appears to be a gravel bike.

As a world-class race bike, the Felt F1x is constructed from Felt’s renowned UHC Advanced + TeXtreme carbon and designed for snappy handling, instant acceleration and durability. Compared to gravel bikes, which are basically touring bikes for the dirt, the F1x is a Ferrari – all raw power and sharp handling.

Custom Felt F1x - Shimano XTR Derailleur & Cassette
The drivetrain on this Felt F1x is as custom as the bike: it has a Shimano XTR rear derailleur and 11-46 casssette with a Rotor crankset, Dura-Ace shifter/levers and Di2 electronic shifting.

The drivetrain on Jay’s custom F1x is a 1×11 Shimano XTR mountain bike rear derailleur paired with Dura-Ace Di2 electronic shifting and a Rotor 3D+ crankset with a Rotor Q-Ring oval chainring. The gearing is customized for dirt and steep climbs with an 11-46 cassette and a 42-tooth chainring. It’s tailor-made for adventuring all over Utah’s mountain and desert roads – and perfect for the Crusher in the Tushar’s 10,000+ feet of climbing.

Custom Felt F1x - Reynolds Attack Carbon Wheel Detail

Wheels are an often overlooked bike component. Not with this bike. The Reynolds Cycling carbon Attack wheels are all about performance. The 24-spoke tubeless-ready carbon wheelset is super stiff and durable yet weighs in at just 1480 grams. The Reynolds Attack wheels are built for disc brakes and come with 12mm through-axles for extra stiffness. The carbon rims are 29mm deep with a 17mm internal width. They’re mounted up with 38mm Maxxis Rambler gravel tires, which offer a balance of speed on hard surfaces and traction on dirt and gravel.

Custom Felt F1x - Shimano Dura-Ace Disc Brakes

If you haven’t tried disc brakes on a road bike yet, get on it. They’re well past the experimental stage and there’s no reason not to have them, anymore. They feel like traditional cantilever brakes but with way better power, modulation and reliability. Jay’s Felt F1x dream bike is fitted with Shimano’s best – flat-mount Dura-Ace hydraulic disc brakes with road-specific 160mm Center Lock rotors. They’re light, aerodynamic and work soooo much better than cantilever brakes.

Custom Felt F1x Gravel Road Bike in Action

With drop bars, skinny tires and no suspension, the Felt F1x is very different from a mountain bike. However, as you can see in the photos here, Jay is having fun exploring new terrain and getting acquainted with his new bike. He’s excited about all the new riding opportunities it opens up in and around Park City; and he’s looking forward to do his fifth Crusher in the Tushar on something faster and lighter than a mountain bike.
