Rohan Dennis’ BMC Timemachine

Dennis crushes USA Pro Challenge time trial as BMC steamrolls race

At the USA Pro Challenge in Colorado, BMC has been crushing all comers, winning stage after stage and leading the overall race. On a windy Friday in Breckenridge, Rohan Dennis powered his BMC Timemachine with a monster 56/44t crankset to the time trial stage win.


Earlier this year, Dennis set the world hour record on a custom Trackmachine and rode into the first yellow jersey of the 2015 Tour de France thanks to his time-trial prowess. Suffice it to say, the guy can ride.

While many of the teams at the US Pro Challenge had single time trial bikes for their riders with road bikes for back up on the follow cars, BMC of course had A and B bikes for all its riders. Dennis’ A and B bikes were identical save the wheels; his spare had sponsor-correct Shimano C50 front and Shimano PRO disc while his race bike had unbranded wheels. The front wheel looks to be a HED GT3 and the rear a Lightweight disc.
