Designed for: 1x Drivetrains 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. The MRP Wave™ chainring technology utilizes a host of features to provide robust chain handling and retention characteristics while providing market-leading durability. ~ Tooth faces displaced from nominal centerline to provide active & positive lateral engagement of every chain link with a chainring tooth. ~ Alternating lateral force to each chain link to actively retain links to ring. ~ Less surface contact between chainring and chain creating minimal friction and maximum retention. ~ Equal tooth thickness on entire chainring to allow for maximum mud-shedding clearance. ~ Tooth design allows for reduced weight chainrings over competitor technology.
