AVONA Callis Shimano GRX Di2 2x12 Gravel Bike

The Avona Callis takes road-bike speed to gravel. It is aerodynamic yet compliant, with room for fast rolling tyres at a low weight, so it can race, explore new roads or double as your road bike.

This is the Avona Callis Shimano GRX Di2 2x12 build in Moon Fall Blue, assembled to order in Germany.
