The Topstone CAAD 1 GRX 2x is the double-ring version of the premium aluminium Topstone, built for riders who want a wider gear range and tighter steps between gears. If your rides mix fast tarmac, long rolling gravel and loaded adventure days, this is the one to look at.
The SmartForm C1 alloy frame carries Cannondale's CAAD heritage: custom-butted and swaged tubes, smooth welds and a lifetime warranty. It's paired with a full carbon fork and OutFront Steering Geometry for a front end that's stable at speed and quick to respond, with room for tyres up to 52mm in the frame and 56mm in the fork.
Shimano GRX 2x12 runs a 46/30 chainset with an 11-36 cassette, so you get a close-ratio feel on the road and still have a low gear for steep climbs. GRX hydraulic disc brakes, WTB ST i25 tubeless-ready wheels, 45mm WTB Vulpine tyres and a clean Conceal cockpit round off a polished all-rounder.
