Pro Bike: Spencer Petrov’s Focus Mares Force 1

Spencer Petrov, the newest addition to Jeremy Powers's Aspire program, will ride a yellow Focus Mares CX at the Pan-Am Championships.

Spencer Petrov and his Aspire Racing teammates, Jeremy Powers and Ellen Noble, will ride the stock paint scheme version of the Focus Mares CX at the US Cup-CX/Derby City Cup in Louisville, Kentucky. They will ride the bikes in coordination with the Pan-American Championships on Sunday. The final round of the US Cup-CX is on Saturday and could see the team on the yellow bikes then as well.

Petrov and Noble ride the SRAM Force groupset, while Powers rides SRAM E-tap. Aspire Racing brought out the bikes quietly at US Cup-CX/Cincy CX and VeloNews was able to borrow Petrov’s new yellow rig for a little while.

The newest member of the Aspire Racing team is a heavy favorite to take home the under-23 Pan-Am Championship in Derby City after powering to second-place on day one of the US Cup-CX/Cincy CX in the first muddy affair of the season. Check out all the details on Petrov’s bike below and the corresponding gallery above.
