Supercaliber 9.9 XX1

Supercaliber 9.9 is the fastest, lightest and most capable cross-country race bike we make – and that's exactly why it's Trek Factory Racing's World Cup bike of choice. The exclusive IsoStrut top tube shock is the cornerstone of Supercaliber's efficient suspension system, giving you a fast and light ride that charges through rugged terrain at breakneck speed.

It's right for you if...

...you're gunning for the top spot and looking for a pro-level cross country racing bike that has top-of-the-line everything. You want a bike that comes spec’d with the best parts and suspension available – plus tons of carbon – for knock-out, drag-out speed and capability.
