Wolf Tooth Elliptical 110 BCD 4 Bolt Chainring for Shimano GRX 38T

PowerTrac Elliptical (PTE) oval chainring wide/narrow for Shimano GRX cranks. The unique design creates an oval ring that provides the benefit of 112 degrees of top dead center after 10% (ovality) timing. Reduces spin in the "power zone" and allows for natural pedaling in the "recovery zone." Wolf Tooth patented chainring. The wide side of the teeth provides maximum contact on the drive side, distributing the load and extending chainring life. The narrow side allows for mud and debris clearance and reduces friction. The alternating wide/narrow tooth pattern prevents chain drop. Compatible chains: 9-10-11spd/12spd SRAM Eagle/KMC/Connex/Wippermann/Campagnolo/SRAM Flatop AXS chain. Drop-Stop B Weight: 72g Material: 7075-T6 aluminum Chain line: 50mm Drivetrain: Shimano GRX crankset including RX600/RX810 S Compatible with RAM flat top chains
