Avanti Gran-Durance 3 Grey

Whether you’re hitting the pavement for that daily commute, weekend fitness, or venturing off the beaten track and onto some rail trails or gravel routes on the weekends, our light and versatile Gran-Durance has you covered.

A comfortable and upright frame accepts up to 700x50mm gravel tyres, for a smooth and confident ride no matter how rough the road gets. Shimano’s new 12sp GRX gravel group and hydraulic brakes take care of the stop and go and offer Shimano’s bench mark performance.

  • Light and tough full carbon gravel fork with clearance for 700x50C tyres
  • Powerful, smooth and wide-range Shimano 2x12sp GRX with hydraulic disc brakes
  • Light and wide rims, butted spokes and Shimano thru-axle hubs for on and off road performance
  • 40mm wide Kenda Tubeless gravel tyres, roll fast on pavement, but will grip on multiple surfaces and resist punctures
