Mrp wave cinch direct mount chainring black

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 mrp s 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 features carefully selected chainline specs for sram direct mount 49mm for 28 34t 50mm for 36t and race face cinch mount 50mm for all sizes rings give you quiet lasting performance direct mount models available for standard and boost chainlines 104mm bcd 110mm bcd direct mount for sram and cinch models machined from durable long wearing 7000 series aluminum ...
