Tom Zirbel's Orbea Orca

Boulder, CO resident Tom Zirbel won the 2013 US Pro TT Championships today on an Orbea Orca road bike set up with aero bars. This 60cm road frame fits this lanky rider best and it did not seem to hold him up. As far as we noticed everybody else was on TT bikes.

We grabbed the bike right after he crossed the finish line.

It is indeed an Orbea Orca road frame.

Tom Zirbel rides a Selle Italia Team Edition saddle.

Hed Corsair bars and a massive negative stem.

SRAM Red shifters and no bar tape on the extensions.

Zirbel rode a 55-42 combo up front and used a 12-28 cassette in the back.

SRAM Red derailleurs front and back.

Tom Zirbel relies on SRAM Red stoppers.

A Hed Singer 9 up front.

Plus a Hed Stinger Disc in the back.

Challenge Crono S.C. tires.
