The integrated guard helps protect the chainring from rocks, roots, logs, and trail impacts. It also removes the need for an extra separate bash guard.
This adapter allows compatible SRAM 3-bolt direct mount cranks to use standard 64BCD 4-bolt small chainrings.
Designed for 22T, 24T, and 26T chainrings, making it suitable for steep climbing, technical MTB riding, low-speed control, and high-torque riding conditions.
Made from high-strength aluminum 7075-T651, offering excellent stiffness, durability, and long-term riding performance.
Fully CNC machined with working accuracy up to 0.03mm. This helps ensure accurate fitment, stable chainring positioning, and smooth drivetrain performance.
Built-in female threads allow direct bolt installation without separate chainring nut caps, making installation cleaner and easier.
