- OCLV Mountain Carbon is race-light and trail-strong
- The IsoSpeed decoupler makes it ride smoother than any other hardtail, so your body doesnt get beat up by trail chatter
- New internal control routing is super easy to use thanks to built-in channels that guide your hose or housing easily through the frame
- You get a Straight Shot downtube for extra-stiff, responsive handling without added weight, and a Knock Block headset that protects against spinning bars and fork crowns
IsoSpeed smooth
IsoSpeed takes the edge off body-beating small bumps and trail chatter so you can stay stronger longer, without giving up any pedaling efficiency.

OCLV Mountain Carbon
Treks mountain-specific carbon fiber is tougher carbon, with unique materials and layup procedures, Treks advanced engineering, and a higher standard of testing.

Straight Shot downtube
Straight Shot downtube gives you an extra-stiff frame without adding any weight, so you can stick your line through the rough stuff and still fly up the next climb.
