Pro bike: Peter Sagan's Cannondale Synapse Hi-Mod

A cushy ride and fully custom geometry

So how important is Peter Sagan to Cannondale Pro Cycling? Team sponsor Cannondale hasn't just cut a custom mold for his everyday SuperSix EVO road racer; Sagan also gets a fully custom Synapse Hi-Mod for the cobbled classics, built with a particularly long-and-low geometry to suit his aggressive riding position.

Just as with his SuperSix, Sagan's Synapse Hi-Mod effectively melds two frame geometries into one: the cockpit length (or reach) is borrowed from a standard 58cm size but the frame's height (or stack) is taken from a far smaller 51cm model. This yields a front end that's a whopping 62mm lower than usual and certainly nothing like the '61cm' label stuck to the down tube.

It says it's a size 61 but Sagan's Cannondale Synapse Hi-Mod is custom geometry

Unlike some of his competitors that might opt for their sponsors' classics machines in much smaller-than-usual sizes – and thus forcing the use of radically proportioned stems – Sagan gets to use a standard 120mm length. More importantly, his position is virtually identical to his usual SuperSix EVO so there's no adjustment required for such critical races.

Luckily for Cannondale, part of the cost of that custom mold can be amortized across multiple riders. As it turns out, that's also lucky for Sagan as a late mechanical in the E3 Harelbeke forced him to swap bikes with teammate Alan Marangoni, who rides the identical frame geometry.

If it's so much trouble, one might wonder why Sagan doesn't just ride his standard SuperSix EVO instead. Cannondale's latest Synapse Hi-Mod incorporates a number of unique features that soften the ride relative to its flagship road racing model, such as radically shaped 'SAVE PLUS' stays, more forward-swept fork blades, and a smaller 25.4mm-diameter seatpost – all of which are designed to give slightly under impact to help improve rider comfort and provide a bit more tire traction.

The Synapse Hi-Mod also incorporates extra clearance for the high-volume tires necessary to survive the brutal Belgian cobbles plus a slightly more relaxed geometry for extra stability.

Speaking of tires, Sagan's tubulars are clearly labeled with 'Kenda SC' hot stamps – but they're unlike anything Kenda currently offers and are more likely handmade tires from another brand that have been rebadged. Otherwise, the rest of the build is quite straightforward, including a SRAM Red 22 group, SRM/Cannondale power meter cranks, FSA cockpit components, a fi'zi:k Aliante saddle with k:ium rails and a plastic shell, Speedplay Zero Stainless pedals, and Vision Metron 40 carbon tubular wheels.
