The Rennen BMX 7075 cassette cog is a lightweight, precision cassette cog machined from 7075-T6 aluminum in the USA by the Rennen Design Group. It features a 3/16" spline surface for maximum driver contact and a specially designed 3/32" tooth profile to help reduce teeth wear. Compatible with Odyssey Race, Sinz, Shimano DXR and any other cassette with Shimano compatible drivers. (0.35 oz - 13T)
Note: Rennen cogs have very tight tolerances to remove drivetrain slop. At first the cog may be difficult to install, but with a little finesse it will wear in.
Why put an old stretched out chain on your new drivetrain? Dans Comp has a large selection of BMX Chains.
