UCI approved: Cancellara’s new mystery Trek

New classics-oriented frame from Trek is on the UCI approved frames list

It appears we may now have a name for the new classics-oriented Trek frame ridden to a win by Fabian Cancellara (RadioShack-Nissan) at the Strade Bianche in early March. The most recent version of the UCI’s approved frames list includes a series of newly approved Trek road frames: the Domane 1, 2 and 3. The frames were approved on January 18, about two weeks before Cancellara’s Strade victory aboard a black, mystery Trek frame. No other new frames from Trek have been approved since the 6-series Madone last year, leading us to believe that the Domane is very likely the frame used by Cancellara at Strade.’s James Huang detailed Cancellara’s mystery frame last week based on photos from the event. We have been aware of Trek’s ongoing classics bike development project for about two years, and it seems the venture is finally close to fruition. Further details are expected later this month.

According to the UCI’s list, the Domane frame will come in three models with the same shape (there is only one listing for versions 1, 2, and 3), likely using different layups and possibly head tube heights. The frame will use a brand new fork dubbed the Bontrager RXL, and will come in eight sizes from 47 to 62cm.

A number of design cues are clearly visible on Cancellara’s Strade Bianche bike. Slender, curved seat stays and a curved fork are a clear attempt at improving compliance. Raised ribs along the downtube and top tube are likely intended to improve lateral stiffness, and Trek appears to have maintained their tapered e2 head tube and BB90 bottom bracket in an effort to do the same. Cancellara’s frame does not appear to have a longer-than-usual head tube, suggesting that the frame may be available with multiple head-tube heights, like the current Madone.

Cable routing is new as well, with both rear brake and front shift housing heading into the same port in the head tube. The curved fork cuts back sharply at the dropouts, providing extra comfort while maintaining normal rake and trail figures.

Photos appear to show plenty of tire clearance both at the fork and stays with Cancellara’s 25c Schwalbe Ultremo tires, suggesting there is room for 28c tires.

Keep an eye out for more as the cobbled classics approach.
