Blackspire N/W Oval Sram DM 3mm 28T

Our boost oval chainring features our highly sought-after tooth profile for the best 1x drivetrain performance. Combine this chainring with a modern-day clutch derailleur and never worry about dropping a chain again. Made specifically for use with any cranks which use a *SRAM interface. Designed for use with 148mm Boost frames.

- Oval shape allows for greater power, increased traction, and a smoother spin
- Blackspire's oval shape has an ovality of 12-13% with a timing of 115 degrees after the top-dead-center
- Highly sought-after narrow-wide tooth design provides excellent chain retention without a chain guide
- Perfect for 1x setups and compatible with 9/10/11, and 12-speed systems. 9-speed drivetrains require a 10-speed chain

- For SRAM DM Boost cranks, 3mm offset for a perfect 52mm chainline
