BMC gravel-race bike. Lower and faster than URS, built for events.
Racers who like Cannondale's handling and want the serviceable frame. Synapse is the taller sibling; SuperX is the CX/gravel race cousin.
The fourth-generation EVO keeps the third generation's geometry but goes lighter, slipperier, and back to a threaded BSA bottom bracket. Same fit as the 2020–2022 bike, easier to live with.
CX and gravel racers who size like a road-race bike. If you want Future Shock and mounts, Diverge is the sibling. The S-Works kit is the halo build — same geometry as the non-S-Works page for this year, different parts.
The light gravel/CX race bike: lower and snappier than Diverge, with less adventure hardware. It feels like a Tarmac that grew tire clearance.
