Features
Alpha Gold Aluminum
Our high-performance lightweight aluminum is continuously cold extruded and butted, and formed into manipulated tube shapes to balance strength and weight saving.
Patrol-ready accessories
Sturdy kickstand and rack come standard. This bike is ready to roll.
Suspension lockout
Locked suspension means your fork remains inactive, increasing pedaling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.
Hydraulic disc brakes
Hydraulic disc brakes offer the absolute strongest stopping power in all conditions, including wet and muddy.
Extended size range
A wider range of sizes than the industry standard provides more option for everyone, from tallest to shortest and all those in between. Because everyone deserves a great ride.
G2 Geometry
Advanced frame geometry and a custom offset fork give our 29ers precise handling at low speed without compromising high-speed stability. We call it G2 Geometry, and it's why our 29ers handle better than anyone's.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.
