ABP

Our patented Active Braking Pivot allows your suspension to work freely whether you’re on the brakes or off. It’s smooth, controlled suspension that’s at its best all the time.

DRCV

With DRCV, you can have it all: supple small-bump feel, great pedaling efficiency, and seemingly bottomless travel for the big stuff.

Alpha Platinum Aluminum

Trek's premium alloy, formed into sophisticated tube shapes for maximum strength and minimum weight.

EVO Link

Our exclusive system connects the main frame to the rear triangle with a one-piece rocker link, creating a stiffer frame for greater control with minimal weight.

Full Floater

We attach the shock to two moving linkage points for greater response over a wide variety of terrain. It feels like more travel, but it’s not. It’s smarter travel.

E2 tapered head tube

E2 tapers from a 1.5" lower to a 1-1/8" upper, placing more material where it matters most for the stiffness of a full 1.5" system without the added weight.

RockShox Reverb with Stealth routing

RockShox Reverb gives you 125mm of seat height adjustment with a hydraulically actuated remote, stealthily routed though the frame itself.

Dropper post internal routing

Frame is prepped for internal routing if you decide to add a remotely adjustable seat post.

Internal derailleur routing

Route your derailleur cables through the frame to keep your bike running smooth and clean.

142x12

A more robust and confidence-inspiring rear thru axle, about 35% stiffer than an open dropout design. And now, a thru axle wheel change is actually quick and easy.

15QR

A 15mm front thru axle makes steering more precise for more control, and the quick-release feature makes wheel removal easy.

29" wheels

The gold standard for smooth, stable riding. Bigger wheels carry more momentum, roll over obstacles more easily, and offer greater stability and more traction than smaller options.

Climb-Trail-Descend

CTD gives you three suspension adjustment options: Climb, Trail, or Descend. It’s a simple, intuitive, high-performance system available on select Fox shocks and forks.

Down tube guard

Replaceable external shield protects the down tube from trail debris.

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.

Fully integrated head tube

A fully integrated head tube eliminates the need for headset cups, reducing overall weight without sacrificing performance.

G2 Geometry

Advanced frame geometry and a custom offset fork give our 29ers precise handling at low speed without compromising high-speed stability.

ISCG mounts

International Standard Chain Guide mounts offer easy chain guide installation and adjustment.

Kashima Coat fork

Kashima Coat metal finish on the fork stanchions reduces friction, for quicker suspension response and improved durability.

Post-mount disc brake

Post mounting is the simplest, most efficient way to mount a brake caliper to your bike. Functions great, reduces weight.

Press-fit bottom bracket

Press-fit BB increases pedaling efficiency and allows for a stronger, stiffer frame structure.
