Gallery: Cannondale’s new Synapse HM road bike

A frame that we believe is Cannondale's upcoming Synapse HM, based on the most recent addition to the UCI's approved frames list, was used by Cannondale Pro Cycling's Fabio Sabatini and Kristjan Koren at Strade Bianche on Saturday. The frame looks to be a replacement for the old Synapse, Cannondale's current endurance road frame. There's a good chance that more of the squad will be on the frames for the rougher cobbled classics. Photo: Kei Tsuji

The new frame features internal routing and a stout downtube. Photo: Kei Tsuji

A kink in the rear stays is likely inteded to add a bit of flex. Photo: Kei Tsuji

We're not entirely sure what this split seat tube is for, but it likely plays some role in the vertical flex of the bike's rear end. Photo: Kei Tsuji
