About this item PowerTrac Elliptical (PTE) oval chainring wide/narrow for Shimano GRX cranks. The unique design makes it an elliptical ring that provides the benefit of 112 degrees top dead center after 10% (ellipticity) timing. Idle rotation in the "power zone" is reduced and natural pedaling in the "recovery zone" is possible. Wolf Tooth patented chainring. The wide side of the teeth has maximum contact on the drive side, distributing the load and extending chainring life. Narrow sides allow clearance for mud and debris and reduce friction. Alternating wide/narrow tooth pattern prevents the chain from falling off. Compatible chains: 9-10-11spd/12spd SRAM Eagle/KMC/Connex/Wippermann/Campagnolo/ For SRAM Flatop AXS chain. Drop-Stop B Weight: 102g Material: 7075-T6 aluminum Chainline: 50mm Drivetrain: Shimano GRX crankset including RX600/RX810 Compatible with SRAM flat top chains
