Rennen Single Speed Cog - Shimano - 14 Tooth - Black

We always love it when we can offer you a quality USA made part, especially when it is at a competitive price. The quality of workmanship displayed by all of the Rennen products we've come across so far is top-notch. The cogs take the best attributes of a Surly Cog but none of the weight. The Rollenlager is the best designed chain tensioner we've used, and the spacer kit has an ingenious design allowing for perfect chainline without leaving you deciding between 1.8, 2.0, and 2.1mm spacers.

Rennen Single Speed Cogs are precision machined from aircraft quality 7075-T6 Aluminum ( 83% stronger than 6061) and anodized black, offering the highest performance at the right price. Rennen Cogs are 3/16" thick at the Spline interface assuring that you won't damage your precious hubs. Only Rennen Cogs offer a single speed specific tooth profile which have been designed to extend tooth life. At 0.6oz (17 grams, 16T) this makes Rennen Cogs one of the lightest on the market.

Shimano splined and compatible with 8 or 9 speed chains.

The perfect choice for a afternoon SS ride or a practice session at the BMX Track!
