Race Face rnwdm28blk Pedal Plate for Unisex Adult, Black

Of all the recent innovations in mountain biking, the Narrow Wide tooth profile featured on the Narrow Wide Cinch Direct Mount Chainring is arguably the most understated progression. Race Face has designed a tighter interface between the inner and outer links to prevent the chain from jumping. The Narrow Wide Cinch Direct Mount Chainring eliminates the weakness of four-bolt interfaces, and its 7075-T6, 4mm-thick, aerospace-grade aluminum transfers pedal loads without flexing, offering the lightest and stiffest interface between Race Face cranks. The Narrow-Wide design helps to retain the chain by preventing jump, which is due to a tighter interface between inner and outer links. Now there's no need for heavy guides, and with the large-ratio spread of modern cassettes and 26- through 36-tooth Narrow Wide Cinch Direct Mount Chainring options from Race Face, you can kiss redundant double and triple cranksets goodbye. The proprietary Cinch spline found on the Narrow Wide Cinch Direct Mount Chainring uses a standard Park BBT-22 bottom bracket tool for installation. This design eliminates the weakness of four-bolt interfaces, and its 7075-T6, 4mm-thick, aerospace-grade aluminum transfers pedal loads without flexing. The Race Face Narrow Wide Cinch Direct Mount Chainring is only compatible with Cinch cranks, comes in 24, 26, 28, 30, 32, 34, 36, and 38t options, and it works with 9-through-12-speed drivetrains.
