Genesis CDA 20 Disc Gravel Bike 2021
If you're new to gravel and adventure riding or simply looking for a reliable all-rounder, the Genesis CDA 20 Disc Gravel Bike is worth serious consideration. It handles like the steel Croix de Fer but has an aluminium frame construction making it a great value alternative. The CDA excels over gravel and rough roads alike, with clearance for wide 42mm tyres and a disc brake design for all-condition versatility. There are also numerous mounting points for mudguards, racks and more so you can set it up for commuting or longer trips.
The drivetrain is made up by Shimano Sora 9-speed components, which perform well and are extremely reliable. The cable disc brakes and 160mm rotors ensure stopping power is excellent, even when it's wet. The bike rolls on grippy 37mm WTB Riddler Comp tyres, ideal for exploring off the beaten track.
