Single Speed Cogs - Aluminum
Best Singlespeed cogs (sprockets) on the market. Thanks to the unique tooth shape, narrow-wide profile and perfect roundness these sprockets will outlast any other aluminium counterpart. Size (Mass +/-1g): 16T(23g), 18T(24g), 20T(29g) Color Black Material cnc machined 7075 Txxx Aluminum. Long-lasting construction. 7mm wide. Finish anodized Compatibility Fits to almost every hub on the market. Please note that some freehubs may be a bit out of tolerance, so the cog may fit tight in such case. This is absolutely normal. Chain compatibility 1X, 6/7/8/9/10/11spd chains. To utilize narrow-wide feature please use 9/10/11spd chain. (Not compatible with halflink chains.) Each tooth is much wider and "square like" compared to a commonly used shape. Addition of narrow/wide profile, taken from our award winning Sram spiderless chainring, provides additional teeth strength and offers greater chain retention if a tensioner or chain gets loose while riding.
