31 Jul Oppy S1 Heritage Bike

The Oppy S1 Heritage Bike features a lightweight, retro-cool, butted Cr-mo frame and lugged fork with disc brakes. Dialled in ‘gravel’ geometry, combined with wide rims and rubber, makes it equally at home out in the back-and-beyond, or thrashing through the city traffic loaded up with racks, fenders and panniers. Quality sealed bearing FSA headset, Shimano drivetrain/splined cranks and full Shimano cables, for years of trouble-free riding.


– Retro-cool, Cr-Mo frame for gravel, touring, or everyday commuting
– Full Shimano drivetrain, shift cables and splined Shimano cranks
