  3. TwistLoc simultaneously locks out front and rear shocks for climbs and sprints with the simple Grip Shift-like motion
  4. Wider Kovee Elite 30 wheels provide better tyre support so you can run lower pressure and get more traction
  5. This short-travel trail bike gives you a suspension set-up that’s capable in several MTB disciplines, and especially suited to endurance events


Features

Will my bike have a curved top tube?

Will my bike have a curved top tube?

Smaller frames (S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. The larger frames (M and ML) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.

Active Braking Pivot

Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.

Straight Shot w/Knock Block

Trek's Straight Shot frame design optimises the stiffness-to-weight ratio for a more responsive ride. You'll be able to push harder and stay more planted on your line when the going gets rough.
