Here are some detail shots of Tyler’s rig for last weekend’s Crusher in the Tushar:
Jamis full carbon prototype CX frame with Ritchey cockpit & San Marco saddle.
Shimano Ultegra Di2 derailleurs, Vittoria 32 file tread tires set up tubeless, and FSA carbon compact 34×50 road crankset w/Shimano Dura-Ace road pedals.
Shimano Ultegra Di2 electronic shifters, and TRP hydraulic disc brakes with converter under the Ritchey stem.
Closer look at rear disc brake. All cables routed internally. Di2 battery mounted under the bottom bracket shell.
Post-race, covered in 4.5h worth of mud, but still shifting and braking like new.
