Wolf Tooth Elliptical 110 BCD 5 Bolt Chainring 42T Compatible with SRAM Flattop

PowerTrac Elliptical (PTE) oval chainring wide/narrow for 110BCD5 arm crank 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. 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 Bolt used: 6mm *Original 2x bolt cannot be used. Weight: 81g Material: 7075-T6 aluminum
