The Wave™ pattern applies alternating lateral force to each chain link to actively retain links to ring – going beyond narrow/wide implementation that relies solely on friction. The Wave™ tooth pattern swings right to left, grasping the interior of the chain for retention, but allowing room for mud, debris, and grit to escape. The Wave™ design creates more open areas for mud and debris evacuation and preserves chain retention in adverse conditions – one of many “Achilles’ Heels” of narrow/wide designs. Designed with mindful consideration of system friction, the Wave™ design actively engages the chain but yields much less concentrated wear than competing designs — spreading the load over large surface areas instead. Tough enough for Enduro, Downhill, and also weight conscious for XC riding. These MTB Wave Tech rings are machined from 7075-T6 aluminum and Hard Anodized to take a beating.
