Endurance Geometry

Ride all day comfortably and confidently - whether crossing the Nullarbor Plain or exploring the Alpine regions. The Belgie Spirit geometry is less aggressive and more stable so you can ride longer than ever. Flat-mount disc braking means you can ride on the hottest and wettest days of the year without compromise. Compound Curve seat stays for small bump relief combined with clearance for up to 32c tyres allows for a smoother ride on rough roads.
