Wolf Tooth Elliptical 110 BCD Chainring for Shimano 110 x 40T 4-Bolt -

PowerTrac Elliptical (PTE) oval chainring, wide/narrow, for 110BCD asymmetric 4-bolt Shimano cranks. The unique design creates an oval ring that offers the benefits of 112 degrees of top dead center after 10% (ovality) timing. It reduces spin in the "power zone" and allows for natural pedaling in the "recovery zone." The wide tooth side provides maximum contact on the drive side, distributing 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 (see image). Bolts used: 6mm. Cannot use genuine 2x bolts.
