The GSD Frame Lock is set-it-and-forget-it security for the GSD. We’ve partnered with ABUS, Germany’s leading lock manufacturer, to create a hardened steel frame lock that’s always there to secure the wide balloon tires of the GSD. The lock integrates with an included ABUS chain, so if you need added security, you can lock the bike to virtually any fixed object—no lamppost is too thick! Get creative with the 130 cm chain: secure both wheels and the saddle, or cover your friends by locking the peloton together.
