The DMR Blade Direct Mount Chainring is a high-performance upgrade designed for mountain bikers looking to shed weight and improve drivetrain efficiency. By replacing the traditional spider and chainring setup, it offers a stiffer, lighter interface that enhances power transfer, though users must ensure their crankset utilizes the specific SRAM 3-bolt direct mount standard before purchasing.

Yes, the DMR Blade is optimized for 10, 11, and 12-speed drivetrains.
If you are using a clutch-style derailleur, the wide/narrow profile typically provides enough retention to remove the need for a chain guide.
It fits cranks that utilize the SRAM 3-bolt direct mount standard, such as the DMR AXE and many SRAM models.
The DMR Blade is constructed from 4mm thick 7075-T6 aluminium for an optimal balance of strength and low weight.
Yes, it typically saves approximately 100g compared to a standard spider and chainring setup.
Verify the chainring is installed with the correct offset and ensure your derailleur clutch is fully engaged.
Check that the chain is compatible with the ring's speed rating (10, 11, or 12-speed) and ensure the chain is properly lubricated.
Remove the crank arm and inspect the 3-bolt interface and lockring for correct torque and potential debris buildup.
To install the DMR Blade, you must first remove your existing crank spider using the appropriate lockring tool. Ensure the contact points on your SRAM 3-bolt crank arm are clean and free of debris. Apply a light coat of grease to the interface threads to prevent seizing before tightening the chainring to the manufacturer's recommended torque specifications.
Compatibility check: This ring is designed for the SRAM 3-bolt standard. Always confirm if your frame requires a 'Boost' or 'Standard' offset chainring to ensure optimal chain line. Regular maintenance involves cleaning the chainring teeth with a degreaser after muddy rides and checking for bolt tightness every few weeks to ensure performance consistency.
