Chainrings - RA Cycles

Platos

The chainring is the one component everything in your drivetrain touches — the chain, the crank, and every watt you put into the pedals. Chainrings at RA Cycles covers 279 products across road, gravel, and mountain setups: standard aluminum rings for everyday riding, carbon fiber options that reduce weight without sacrificing stiffness, oval profiles that vary the resistance across the pedal stroke, and aero-shaped rings engineered to reduce drag where it counts.

Compatibility spans every major interface standard — Shimano 4-bolt and GRX, SRAM AXS direct mount and 3-bolt, Campagnolo, Race Face Cinch, and Easton — with options from Carbon-Ti, Digirit, Wolf Tooth, 5DEV, SRAM, and Campagnolo. Whether you’re replacing a worn ring, optimizing gearing for a specific discipline, or speccing out a build from scratch, the collection covers the full range.

About Chainrings

Chainring selection comes down to three decisions: compatibility (your bolt circle diameter and interface standard must match your cranks exactly), material (aluminum is durable and widely available across all disciplines; carbon fiber saves weight but is specific to road applications), and tooth profile (round rings deliver consistent power throughout the pedal stroke; oval rings vary the resistance to emphasize the power phase). Getting these right is one of the more impactful drivetrain upgrades you can make — the wrong choice means a ring that won’t fit or a chain that won’t shift cleanly.

RA Cycles stocks chainrings for road, gravel, and mountain setups across every major compatibility standard. Carbon-Ti and Digirit represent the premium carbon end — with rings engineered for Shimano 12-speed Dura-Ace cranks that reduce weight without sacrificing stiffness or chain retention. Wolf Tooth covers the broadest compatibility range in the collection, with round and oval rings for SRAM, Shimano, GRX, Race Face Cinch, and Easton interfaces. Campagnolo, SRAM, and Sugino supply their own chainrings for matching group builds and track applications.

Shop cranksets and chainrings for complete crank and ring setups, browse Wolf Tooth components for cross-compatibility options, or explore full groupsets for a complete drivetrain upgrade.

R&A Cycles - 50th Anniversary

50 YEARS AND COUNTING

From a Brooklyn storefront to flagships in Walnut Creek and Miami, from handwritten mail orders to a fully digital custom bike builder — RA Cycles has spent half a century doing one thing: serving riders who demand the best. That half-century belongs as much to you as it does to us. The riders who kept coming back, who sent their friends, who trusted us with bikes that matter — you're the reason we're still here. Here's to the next fifty.
