Trek Top Fuel 9.8 Mountain Bike

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. 

The high-end mountain bike parts spec comes dripping with carbon, and includes the highest-performance drivetrain, brakes, and wheels you can get. Watch the bike in action here.
