Procaliber F/S ML 29 Crystal White/Trek Black

Procaliber frameset is a race-worthy carbon cross country mountain bike frame thats light, fast, and built to win. It has the unique advantage of IsoSpeed, a decoupler at the top tube/seat tube junction that gives you more compliance on rough trails for a smoother, faster ride.

• 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.
