It's right for you if...

You're a trail veteran and a regular at your local XC races. You want parts upgrades that make you faster, like lighter carbon wheels and a wider-range drivetrain that saves your legs on the steepest climbs.

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 drivetrain, hydraulic disc brakes, fast 29" Bontrager Kovee Elite 23 carbon wheels and a carbon seatpost.

The final word

An awesome bike for serious racers. The upgraded fork and carbon wheels give you big weight savings for a faster ride.

Straight Shot downtube

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

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.

Sizing & fit

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
