Newly re-crowned US National Cyclocross Champion Katie Compton won her eleventh title this month in Austin on a bike she helped develop over the course of her two-year relationship with Trek.

Continuing our annual tradition of looking at Compton’s winning bike, we grabbed an exclusive look at her 2015 Trek Boone 9 disc brake bike, fresh off her victory in Austin, with a half lap of the Zilker Park course’s mud still coating the tires and pedals (no recycled photos here, see her Trek Boone from 2014 Nationals and Trek Crockett from 2013 Nationals for past bike photos).

We also chatted with husband Mark Legg-Compton about Compton’s setup including pedal choices and the chain drop issues she face earlier in the season. See more of our ever-growing 2015 National Championship bike profiles here.

Compton’s Trek Boone 9 carbon cyclocross bike with the Isospeed seat mast and fork features Shimano components and hydraulic disc brakes, a change that came with joining the Trek Factory Team. Gone are SRAM Red components and her longtime favorite, Wick Werks chainrings.

The 2015 Cyclocross National Championships represents the first time this season Compton has started and finished on disc brakes.
