A Gearing system to maximize your Brommie performance. (No more chamfering)

We know how you value your brommie, so BIKEgang has worked with ATS to present the newest 2015 version SPEED DRIVE with specially designed lock rings, no more chamfering on BB shell, and this means no more chamfering tool to buy or rent.

ATS - Speed drive is a gearing system that makes the chainring spinning at a higher rate. For instance, 38 tooth chainring with speed-drive engaged, will work like a 1.65 times larger one (63 tooth chainring). ATS Speed drive is manufactured under license of Schlumpf Innovations GmbH, (Switzerland) since 2005. All components are made in Taiwan and assembled in Taiwan.
