The Topstone CAAD 1 GRX 1x is the premium single-ring build in the new aluminium Topstone range. It's for riders who like a clean, simple drivetrain and quick, responsive handling when the road turns to dirt, broken tarmac or forest track.
At its heart is the SmartForm C1 alloy frame, built with Cannondale's CAAD know-how: custom-butted and swaged tubes, smooth welds and a lifetime warranty. A full carbon fork keeps the front end light and accurate, and OutFront Steering Geometry gives you a bike that's calm at speed but still nimble in tight spots. There's room for tyres up to 52mm in the frame and 56mm in the fork, so you can go bigger as your riding gets rougher.
Shimano GRX 610 1x12 with a 10-51 cassette gives you a wide spread of gears without a front mech, while GRX hydraulic disc brakes, WTB ST i25 tubeless-ready wheels and 45mm WTB Vulpine tyres balance speed and grip. The Conceal stem tidies up the cockpit and doubles as a computer mount.
