SDS-30B
30t Socket Drive Sprocket milled from Domestic 7075 aluminum plate. This sprocket 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.
The Socket Drive will fit Flatware cranks, and our upcoming Socket Drive Spindles for use with 22mm square end style crank arms (Primo/Quamen/Etc). Standard bolt drive slots are milled into this sprocket to allow the use of any current crank arm with our Socket Drive to Round Bore Adapters. These will be offered in 3/4", 22mm & 15/16" diameters. We will also offer a SD-J500 48 spline adapter for use with 3/4” 48 spline spindles without the need for a drive bolt.
Tooth width - 1/8”
