With patent pending Wave™ retention technology
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.
ADVANCEMENTS OVER NARROW/WIDE
The MRP Wave chainring technology utilizes a host of features to provide robust chain handling and retention characteristics while providing market-leading durability. Technological features and benefits include the following:
- 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.
