The Leonardi S3 Round 8-Bolt Direct Mount Ring delivers efficient power transfer and precise chain engagement for riders who demand reliability on every ride. Designed for modern drivetrains, this chainring is built to perform under the torque and shifting precision of today’s 12-speed systems.
With a 3mm offset, it provides ideal chainline alignment for smooth, quiet operation. The 8-bolt direct mount interface ensures a solid connection to compatible cranksets, creating a stiff and responsive pedaling platform. Whether replacing a worn ring or fine-tuning a drivetrain, this chainring offers the right balance of strength, weight, and durability for both trail and enduro riders.
