The tech you get
A light and stiff carbon frame with trail-smoothing IsoSpeed, a lighter RockShox Reba RL fork with a Solo Air spring, Motion Control damper and a remote lockout, an extra-wide-range SRAM GX Eagle drive train, hydraulic disc brakes, fast 29" Bontrager Kovee Elite 23 carbon wheels and a carbon seat post.
The final word
An awesome bike for serious racers. The upgraded fork and carbon wheels give you big weight savings for a faster ride.

- The new SRAM GX Eagle drive train gives you an extra-low climbing gear that saves energy over the long haul
Features
Our innovative decoupler allows the seat tube to rotate independently from the top-tube-to-seatstay junction, increasing vertical compliance without compromising pedalling efficiency.

Straight Shot downtube
Straight Shot downtube gives you an extra-stiff frame without adding any weight, so you can stick your line through the rough stuff and still fly up the next climb.
Knock Block has your frame's back when things go wrong. It prevents your handlebars from spinning all the way around in a crash, so your hoses won't get yanked and your controls won't hit the top tube.
