We designed some clever interchangeable dropouts that significantly alter the geometry of the bike, so the road bike feels like a road bike, and the gravel bike feels like a gravel bike. No compromises, just speed. DOING MORE SO YOU CAN DO MORE Cervélo knew there was interest in both gravel and road performance e-bikes, so we designed dropouts that make one frame do double duty.
