- The SRAM GX Eagle AXS drivetrain is smart, smooth, and completely wireless
- RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
- The Fox Performance 36 fork gives you four-way damping adjustments for extra-dialed suspension
- We expanded our size range to ensure a better fit for all riders. And, you get the fastest wheel that fits your frame: XS frames get 27.5˝ wheels, S frames get to choose between 27.5˝ or 29˝, and sizes M to XL get 29˝ wheels
Will my bike have a curved top tube?
Smaller frames (XS and 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. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
Internal Storage
Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.
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.
RE:aktiv with Thru Shaft
RE:aktiv with Thru Shaft gives you unmatched grip and control with a shock that reacts to the terrain faster than anything else out there.
Straight Shot w/Knock Block
Treks Straight Shot frame design optimizes the stiffness-to-weight ratio for a more responsive ride. Youll be able to push harder and stay more planted on your line when the going gets rough.
