Race Face

Narrow Wide Chainring

Of all the recent advancements in mountain biking, e.g., fat bikes, 27.5in wheels, carbon everything, and clutch technology in derailleurs, quite possibly the biggest progression is the Narrow Wide tooth profile found on this 104mm-BCD Race Face Chainring. This design helps 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 30- through 38-tooth options from Race Face, you can kiss redundant double- and triple-cranksets goodbye. The Narrow Wide Chainring has a 104mm four-bolt interface, and its 7075-T6 aluminum, aerospace-grade-strength 4mm-plate thickness transfers pedal loads without flexing. The Race Face Narrow Wide Chainring is only compatible with 104 BCD cranks, comes in 30, 32, 34, 36, and 38t options, and works with 9-, 10- and 11-speed drivetrains. Please note that the 30t option is threaded for standard M8x0.75 chainring bolts.
