Tinkoff-Saxo rider Roman Kreuziger raced Sunday’s Liège–Bastogne–Liège aboard a prototype Specialized frame, which appears to have been a new version of the brand’s popular road frame, the Tarmac.
In an image posted to the Tinkoff team’s website Monday, the new frame appears to utilize a new seat binder that is integrated into the frame’s top tube, just in front of the seatpost insertion point. Many manufacturers are employing this type of binder system, which is designed to put less stress on the carbon in the seatpost.
Specialized last updated the Tarmac frame in 2011, with the SL4.
When reached for comment Monday, Specialized confirmed that Kreuziger was aboard a prototype frame on Sunday, but would not provide details on the bike.
“Specialized relies on feedback from professional athletes in developing and testing advanced prototypes in real-world applications. We call these bikes Project Black,” Specialized spokesperson Chris Reikert said in an email when contacted by VeloNews.
We hope to learn more on this new frame in the coming days.
