3D machined 7075 alloy Chain disc. Ideal to fit to your DMR Cult cranks 25t, 27t and 29t Purple, Blue, Grey, Red and Green.

DMRS new DMRCOLOUR components are CNC machined, forged or a combination of both for the best possible combination of strength, weight, price and surface finish.

The surface finish is the critical element, allowing the anodizing to really shine out. DMRCOLOUR components are designed to match our Alloy Wingbars, Nutz, Swarm stems, Tilt seat posts, Grab seat clamps and Hubs.

Spin chain rings have a 15/16th internal bore for the crank axle and are supplied with a spacer to fit a 19mm crank axle. Designed to run with single speed chains only. 25, 27 and 29 tooth Spin rings are designed to fit Standard drive cranks.

NOTE: All chainrings below 25t (20t, 22t) are NANO DRIVE and will NOT work with standard BMX cranks because the bolt pattern is different. Nano Drive compatible cranks include the DMR Cults.
