10 Aug Oppy S Heritage Bike

The brand new Oppy S Heritage Bike features a lightweight, retro-cool, butted Cr-mo frame and lugged fork with disc brakes. Dialled ‘gravel’ geometry, combined with wide rims and rubber, makes it equally at home out in the dirt, or thrashing through the city traffic. Smartly designed frame with eccentric bottom bracket, derailleur hanger and removable cable guides, plus a rear hub that will take 8, 9 or 10sp cassettes, mean swapping to a full drive train is a breeze
