SRAM Direct Mount GXP Chainring

What Our Gearhead® Experts Are Saying:

"This is my go-to round ring for Boost SRAM builds. It’s quiet, durable, and holds chainline perfectly, even on hard-charging trail bikes."

The Round Boost N/W Direct Mount Chainring is engineered for riders running modern Boost-spaced 1x mountain drivetrains who want predictable performance and rock-solid chain retention. We rely on it for trail and enduro riding where drivetrain noise, dropped chains, or inconsistent chainline quickly ruin a ride. Designed by absoluteBLACK, it focuses on clean execution rather than unnecessary complexity.

CNC-machined from 7075 aluminum, the chainring delivers excellent stiffness-to-weight performance and resists wear under sustained torque. The narrow-wide tooth profile engages the chain securely through rough terrain, while the round profile maintains a natural pedaling feel that many riders prefer for technical climbing and long days on the bike. The direct mount interface reduces flex and removes the need for chainring bolts, simplifying installation and improving durability.

With a Boost-specific 3mm offset, the ring maintains a 52mm chainline suited to modern Boost frames and compatible Super Boost configurations that use SRAM-specific crank axles. It integrates cleanly with a wide range of SRAM direct mount cranksets and supports modern 1x drivetrains, making it an ideal choice for riders seeking a quiet, reliable, and straightforward chainring for aggressive mountain riding.
