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 Blue/Rose, assembled to order in Germany.
