absoluteBLACK 28t Oval Chainring Shimano Direct Mount 3mm Offset

absoluteBLACK Oval Direct Mount 1x Chainring for Shimano Cranks

Elevate your trail performance with the absoluteBLACK Oval Direct Mount 1x Chainring—engineered to deliver unmatched efficiency and durability for Shimano XTR M9100, XT M8100, and SLX M7100 cranks. Designed exclusively for 12-speed Hyperglide+ chains (CN-M9100/8100/7100), this chainring combines cutting-edge engineering with rider-centric benefits to transform your ride experience.

Crafted from aerospace-grade CNC-machined 7075 aluminum and treated with a robust anodized finish, this lightweight component sheds excess weight while maintaining exceptional strength-to-weight ratios. Its ovalized design—optimized at 14.4% ovality and timed between 110.5-116.3° after top dead center—reduces knee strain during climbs and sprints, keeping your legs fresher over long miles. The teeth’s 3D-machined profile ensures seamless mud clearance and quieter chain engagement on rugged terrain.

Key Advantages Over Traditional Setups:
– Direct Mount Integration: Eliminates the need for a spider assembly, saving grams without sacrificing stiffness.
– Boosted Efficiency: Oval geometry aligns power output with natural pedal strokes for smoother transitions between gears.
– All-Conditions Performance: Mud-shedding teeth excel in wet or muddy conditions, maintaining consistent traction on technical trails.
– Hub Compatibility: Works seamlessly with both standard (135/142mm) and Boost (141/148mm) MTB hubs for versatile drivetrain setups.
