SDS Sprockets

Socket Drive Sprockets milled from Domestic 7075 aluminum plate. These sprockets features MIL-A 63576 Hard Anodize with Teflon Impregnation for a harder, slicker surface for increased chain life and reduced wear. The tooth root radii have been relieved to allow the inner plates to only ride on the center width of the tooth, resulting in a smoother, quieter operation even when chainline is not ideal. This also helps reduce packing dirt into your chain.

The Socket Drive will fit Flatware/Thunderbolt cranks, and our upcoming Socket Drive Spindles for use with 22mm square end style crank arms (Primo/Quamen/Etc). We will also offer a SD-J500 48 spline adapter for use with 3/4” 48 spline spindles.

Sizes - 15T, 18T, 20T, 25T & 30T
Tooth Width - 3/32"
