Forme Calver Cyclocross Frameset Black-58cm

The all-new and refined Calver frame stretches beyond a thorough-bred Cyclocross racing frame. With on-point geometry, exceptional clearance and class leading weight, the Calver can be custom built and capable of it all.


The Calver series has become one of our most iconic product ranges over recent years, with no fewer than 5 world and national championship or series wins. Designed initially as a pure thoroughbred-racing tool, for the specific demands of a Cyclo-Cross race.


The refined Calver frame is one of the lightest aluminium disc-brake compatible aluminium frames available. Developed with the assistance of some of the UK?s most experienced and successful Cyclo-Cross racers our ambition was to deliver race-winning performance at an affordable real-world price point. Its geometry, weight and general all round ability are factors which lend themselves perfectly to being a rocket race machine for cyclo-cross and criteriums as well as an all-day adventure companion. Perhaps the N+1 rule should be applied to wheelsets instead!
