Bought this off Ebay last year and built it up with Campagnolo Chorus. Initially had Mavic Ksyrium SSC on but have since upgraded to Revolution Rev-50X. This bike rides like a dream. After years of training on Road race bike it was a revelation going to an endurance road ride. The frame is stiff without being harsh without the "noodlely" feel you would expect from the more comfortable geometery.
