Introducing the Rennen Single Cog Spacer

The Rennen Single Cog Spacer re-invents the current integration of single-speed cogs to multi-speed cassette hubs. Gone are the days of cheap cassette spacers, and less than perfect chain alignment.

The Single Cog Spacer is composed of a set of threaded couplers; one on each side of the cog. To adjust the chainline, simply thread down one side, and expand the other. The Spacers are reverse threaded so that when the system is tightened down with our 7075-AL Locknut you are assured that your cog is secured in place.

Construction is comprised of CNC machined parts, with a durable ano-coating, and laser etched graphics.

The elegant design is a must for the high-end customer, looking to put the finishing touch on a quality single-speed bicycle.
