Cannondale Topstone 2 Womens Gravel Bike 2021
The Canondale Topstone 2 Women's Gravel Bike delivers a steady and sure-footed off-road ride, with light handling and an excellent set of components. The key differences with the women's model, are the female-specific saddle and comparitively narrower handlebar, making the bike feel more comfortable to the majority of women, straight out of the box.
Cannondale has vast experience producing some of the best alloy frames out there, and with the SmartForm C2 material, this is a strong and lightweight bike. Also benefitting from a full carbon fibre fork, you'll enjoy lightweight steering that absorbs vibrations from the road or trail too.
The Shimano GRX 400 groupset is perfect for off-road or mixed surface riding, as the rear derailleur features a clutch mechanism to dramatically reduce chain slap. The hydraulic disc brakes are powerful, making stopping in wet or dry conditions equally reliable. Thick 37mm tyres allow for added traction on soft surfaces, while there are ample mounting points for racks, bottles and even mudguards.
