Why Dean?
Lightweight, responsive, with more gears and frame sizes than our SRAM-geared single chainring gravel bikes, our latest Dean is a great choice for riders looking for an outstanding blend of value, versatility, and performance. The Dean won’t just survive but thrive wherever your ride takes you.
Features & Equipment
With its proven trail-taming handling it’s got the edge when the road stops, too. The same ride anywhere mountain bike (MTB) inspired handling as the rest of our gravel range – together with wide rims and tyres – are a license to leave those roads far behind and head over the hills, into the forests and down unknown trails. And when you do, the reinforced Schwalbe tyres, 2x10 Shimano GRX gears and brakes – together with full bottle, rack and bikepacking mounts – mean the Dean is a fast, efficient and super tough all-rounder. Sealed cable ports and masses of mud clearance, together with being fully mud-guard ready – just add our own Whyte mudguards all combine to ensure that bad weather will never hold you back.
