From the pit: U.S. national cyclocross champion Katie Compton’s Trek Boone

As the reigning 13-time U.S. cyclocross champion, Katie Compton has an unrivaled record on ‘cross races on American soil, it’s safe to say no one has won more cross races in the U.S. than Compton. For this reason and more, Compton is one of the big protagonists in any UCI cyclocross World Cup, especially one held in Waterloo, Wisconsin. Compton and her mechanic (whose also her husband, Mark Legg-Compton) also has a reputation for paying attention to the details of her equipment, as a result Compton’s custom Trek Boone, shows lots of special touches that goes deeper than the custom paint job.

Compton is using the latest Dura Ace RD9170 Di2 rear derailleur, whose Shadow geometry and greater cassette range is a good fit for the rigours of cyclocross.

Compton has paired her Dura Ace 9000 crankset with Wick Werks chain rings, for custom gearing.

Compton is running non-series Shimano R785 Hydraulic Di2 shifters, rather than the latest and more compact Dura Ace R9170.

The hydraulic calipers and disc are also non series R785, matching the shifters.

The front derailleur is still the previous R9070 generation Dura Ace.

Compton's XT pedals looks well worn, they've seen a lot of miles.

Compton’s drivetrain is an all Shimano affair, but it is a mishmash of different series, rather then the usual homogeneous group sets we are use to seeing on pro bikes. She’s got the latest wide range Dura Ace RD9170 Di2 rear derailleur, but the hydro shifters and brake calipers are Shimano’s non-series R785 set up. Whether that is due to availability or preference is unclear, the taller knobs on the R785 shifters are a nice fit for cross. She is also running a previous generation Dura Ace R9000 cranks, paired to a set of Wick Werks chain rings in an unusual 42/34 combo. No 1x here and the slightly lower gearing does not appear to slow her down.

Showing off Trek's Project 1 capabilities, the paint job transition beautifully from a deep blue to sky blue.

This is Katie F'n Compton's bike, don't you know.

As one of Trek’s premier athlete, Compton gets a the full Project One custom paint treatment, with a stars and stripes paint scheme worthy of the 13-time U.S. national champion. The paint also incorporates a nice personal touch, featuring Compton’s moniker KFC, for Katie F’n Compton. Something that had originally started out as something of a joke, has now evolved into somewhat of trademark, and has stuck as her social media handle, as well as onto her bike.

Compton runs the Bontrager Blendr mount backwards, mountain bike style, on her Bontrager stem. The mount makes for a clean cockpit.

Compton uses a Bontrager Montrose Saddle.

This Clement MXP on the rear has seen a lot of miles

Custom shrink wrap on for the Di2 cable, details, details.

The ISO Speed decoupler that gives the Boone it's bump eating ability.

Custom wheel stickers for the US champ.

The rest of the bike is finished off with smattering of pretty standard Bontrager components, while rolling stock is handled by Knight wheels, which for Waterloo, is shod with Clement MXP tires. Look for this bike under Compton at the front of just about any start line.
