OCLV Mountain Carbon

Trek's mountain-specific carbon fiber is tougher carbon, with unique materials and layup procedures, Trek's advanced engineering, and a higher standard of testing.

OCLV Mountain tested

Nobody tests like Trek. It's how we know our carbon is the toughest, and the best.

Carbon Armor

External shield protects the carbon down tube from trail debris.

ABP Convert

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.

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.

26" wheels

The MTB standard for versatility, light weight, and maneuverability.

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.

Fully integrated head tube

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

BB95

The stiffest carbon bottom bracket on the market. A Trek exclusive.

ISCG mounts

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

Internal derailleur routing

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

Direct-mount derailleur

Derailleur attaches directly to the frame for accurate shifting in a lightweight, minimal package.

Post-mount disc brake

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

DRCV rear shock

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

DRCV fork

Ride bigger lines, flow through braking bumps with ease, and ride with more control.

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.

Magnesium 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.

15QR

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

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.

3x10

A 10-speed cassette and 3-ring crankset deliver a closer-ratio drivetrain, a wider range of gears, and increased efficiency and durability.

Hydraulic disc brakes

Ultimate control and stopping power in all conditions, including wet and muddy.
