DMR Blade Ring Bicycle Chainrings The Blade chainring is now 10, 11 and 12 speed compatible. Manufactured from stiff 4mm wide 7075-T6 Aluminum maintaining direct power transfer, this MTB direct mount chainring has a wide/narrow tooth design for ultimate chain retention and when combined with a clutch mech, no chain device is needed. Engineered for aggressive trail riding and reliable drivetrain performance, this direct-mount chainring pairs stiffness and durability with lightweight construction to improve pedal response and efficiency. The 7075‑T6 aluminum and 4mm width minimize flex under load for direct power transfer, while the wide/narrow tooth profile maximizes chain retention on rough terrain. When used with a clutch derailleur the need for an external chain guide is eliminated, simplifying setup and reducing weight. Easy to install and compatible with modern drivetrains, it’s an ideal choice for riders seeking dependable mountain bike performance and secure chain control.
