Cinelli Zydeco GRX Disc Gravel Bike 2021
The Zydeco GRX Disc Gravel Bike from Cinelli pairs its versatile aluminium gravel frame with Shimano’s dedicated gravel GRX groupset. The 1x set-up has an 11-42 tooth cassette and a 40-tooth chainring for the ability to climb steep slopes with ease and the hydraulic disc brakes keep things under control in even the worst conditions. The frame itself is quick and responsive to make short rides fun, but can also take mudguards, racks and luggage when venturing further afield.
Highlights
- Columbus Zonal triple-butted alloy frame with clearance for 700x40mm tyres and top tube Bento box studs
- Shimano GRX 1x 11-speed groupset
- Shimano GRX hydraulic disc brakes
- Mudguard and rack compatible
- Manufacturer claimed weight: Frame - 1,760 grams / fork - 450 grams
