"What an XC race bike should be"
"Procaliber offers a more comfortable ride than a traditional hardtail. It's noticeable right away. Ready to go uphill and down with no regard for anything except stopping to get on the podium."

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
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.
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.
Easier internal routing
Integrated channels in the frame make it super easy to route cable housing and brake hose so you get a clean set-up with no hassle.
Watch the videoKnock Block
Knock Block has your frame's back when things go wrong. It prevents your handlebars from spinning all the way around in a crash, so your hoses won't get yanked, and your controls won't hit the top tube.
