MRP Wave Cinch Oval Chainring Race Face - Black - 30t}, Black
  • £12.99
  • RRP £59.99
  • Saving you £78

MRP Wave Cinch Oval Chainring Race FaceThis high-quality mountain bike (MTB) chainring features standard teeth with an Oval chainring shape, which allows you to benefit from increased power with less effort. This makes it ideal for all-day epics on your favourite mountain routes and beyond. Another highlight is its 49mm chainline and Race Face CINCH Direct Mount design, which makes it simple to integrate into your existing setup. Made in the USA, this is an excellent choice of upgrade for dependable chain retention and performance as you hit the trails.The Wave pattern applies alternating lateral force to each chain link to actively retain links to the 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. Machined from durable, long-wearing 7000-series aluminium.Wave Chainring Technology AdvancementsThe MRP Wave chainring technology utilises a host of features to provide robust chain handling and retention characteristics while providing market-leading durability.- Tooth faces displaced from nominal centreline to provide active and positive lateral engagement of every chain link with a chainring tooth.- Alternating lateral force to each chain link to actively retain links to the ring.- Less surface contact between chainring and chain creating minimal friction and maximum retention.- Equal tooth thickness on the entire chainring to allow for maximum mud-shedding clearance.- Tooth design allows for reduced weight chainrings over competitor technology.Features: Material: CNC-machined 7075 Aluminium Use: Mountain Bike (MTB) Mount Type: Race Face CINCH Direct Mount Teeth Type: Standard teeth Chainring Shape: Oval Chainline: 49mm with RXC and RF134 spindles, 50mm with RF134 spindle Compatibility: Shimano 9/10/11 speed and SRAM 9/10/11/12 speed compatible (not compatible with 12 speed) Number of Chainrings: Single Designed for x1 drivetrains Not reversibleManufacturer's Part Numbers: MR-23-1-241 Black 30T RaceFace MR-23-1-242 Black 32T RaceFaceBuy MRP Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
