absoluteBLACK Oval Direct Mount 1x Chainrings for CINCH are specifically engineered for Race Face cranks that use the CINCH system. By eliminating the need for a traditional spider and chainring setup, this direct mount design offers notable weight savings without compromising strength. Precision CNC-machined from 7075 aluminum and finished with hard-wearing anodization, these chainrings are built to withstand demanding conditions. Each ring’s ovality is optimized per size, ranging from 10.2% to 14.4%, with timing set at 110.5°–116.3° after top dead center for maximum efficiency. Features Optimized oval shape reduces knee strain and muscle fatigue, all while feeling natural on the bike Narrow-wide tooth profile ensures secure chain retention 3D-machined teeth improve mud clearance and promote quieter drivetrain operation Outstanding strength-to-weight ratio Not compatible with Shimano 12-speed Hyperglide+ (HG+) chains
