Cannondale Topstone LTD Gravel Bike 2022
Offered with striking LTD graphics, this Cannondale Topstone Gravel Bike combines style with comfort, great handling and versatility. It pairs a C2 alloy frame with a carbon fork and uses OutFront Steering geometry to provide precise steering, and a stable yet agile ride feel.
Built up with a Shimano GRX 800 groupset in a 2x configuration, you get a wide range of gears and precise, reliable and quiet shifting. Hollowtech II crank arms keep weight down, and Shadow RD+ technology in the rear derailleur improves chain retention and reduces chain slap and drop. The hydraulic disc brakes ensure performance is powerful and consistent in all conditions.
Well-equipped for bigger days out, overnighters and bikepacking, there are numerous mounting points on the frame and fork for bottles, mudguards and luggage. The rear mudguard bridge can be removed if you want to minimise weight for faster rides too.
The bike rolls on WTB wheels and tyres in a 37mm width, and the tubeless-ready design means you can benefit from even more traction and bump-absorbing comfort. You can go wider still, with the ability to fit tyres up to 45mm, and it's even possible to swap out the seatpost for a dropper post if you're planning on tackling steeper, more technical terrain.
