Single speed free cog from ACS, a long-established brand of BMX parts.
With three claws, the ratchet that hangs every 12˚ (30 notches) is characterized by high strength and little power loss when stepping on. Install and remove with the original 6 spline tool.
It is durable and has good performance, and the price with a low replacement hurdle when you want to change the gear ratio is also attractive. Since there is a lineup of up to 22T, which is rare for free cogs, it is also ideal for single speeders that require a light gear ratio.
Number of teeth: 13T, 14T, 15T, 16T, 17T, 18T, 19T, 20T, 22T
Up to 15T is compatible with Smaller M30 Thread, and 16T and above is available as a single speed hub standard.
Compatible with thin teeth (3/32 ")
* Special tool for installation (ACS Free cog toolOrCrossFire Spanner) Is required
