Cannondale Topstone Carbon Ultegra Disc Womens Gravel Road Bike 2020
Cannondale is redefining the capabilities of gravel riding and pushing you towards new horizons with the women's Topstone Carbon Ultegra Disc Gravel Road Bike. The frame features the advanced bump-smoothing KingPin suspension that allows the back of the bike to give you up to 30mm of road-smoothing compliance, slowing your rate of fatigue and elevating your fun. The geometry is optimised for endurance riding - slightly more upright for comfort and stability, yet low enough that when you want to push the pace your body position feels fast. The LockR Pivot further stabilises the back of the bike by securing the seatstays for greater rigidity and acceleration.
The Ultegra mechanical groupset is geared towards performance; lightweight yet robust to withstand the roughest conditions. An 11-34t cassette pairs with a 46/30T chainset that offers plenty of range for long climbs and the powerful hydraulic disc brakes will inspire confidence on loose surfaces so that you can perfectly feather your speed and maintain absolute control.
Delivering a nice touch of smart tech is the integrated wheel sensor that lets you accurately monitor speed, route, and distance info from the free Cannondale App.
