Cannondale Topstone Carbon 105 Disc Gravel Road Bike 2020
Raising the bar in gravel and adventure riding, the Cannondale Topstone Carbon 105 Disc Gravel Road Bike draws inspiration from the full family of Cannondale machines to optimise comfort, ensure speed and efficiency and guarantee fun across all surfaces. Foremost, the revolutionary KingPin Suspension smooths out vibrations and bumps by delivering up to 30mm of relief without adding weight or mechanical complexity, helping to stave off fatigue. The geometry slots the rider into an Endurance Fit that delivers the right mix of stability for comfort and control on long adventures whilst still feeling fast when the route ahead prompts you to get low and push on. Further enhancing handling and performance is the LockR Pivot that secures the left and right seat-stays for a more secure ride and instant response when you need to drive hard on the pedals.
This bike has a brain too, with an intelligent, integrated wheel sensor providing speed, route and distance info, as well as suggestions for servicing and ongoing maintenance, all through the Cannondale App. Bringing the reliable Shimano 105 groupset across from road disciplines, powerful hydraulic disc brakes will keep you moving on remote roads, whether climbing, descending or pounding the flats in all conditions. When it comes to carrying your gear for overnighters there is plenty of space for mounting accessories, bags and water bottles and the mudguard-ready frame will keep your stuff clean when the weather turns.
