Trek enlisted multiple World Cup-winning Katie Compton to design the ultimate cyclocross racing bike. The result is the Boone 9 Disc, a bike with 'cross-specific features like plenty of mud clearance, exceptional race geometry, a chain keeper, internal cable routing, and an easily shouldered top tube. The OCLV carbon frame and E2 carbon fork is, of course, stiff and precise, yet Trek’s innovative IsoSpeed decoupler adds comfort and compliance to every bumpy, rutted out course. Combine that with the flawless shifting of 11-speed Ultegra and the top-end performance of Shimano hydraulic disc brakes, not to mention tubeless-ready Bontrager wheels with fat tires and a slew of lightweight Bonty components, and you're ready to climb the top step on the podium.
