Wolf Tooth Elliptical Direct Mount Chainring for SRAM 38T Chainring 8-Bolt

PowerTrac Elliptical (PTE) oval chainring wide/narrow for SRAM 8-bolt cranks. Unique design results in an oval ring that offers the benefit of 112 degrees top dead center after 10% (ovality) timing. Reduced spin in the "power zone" and natural pedaling in the "recovery zone." Wolf Tooth patented chainring. Wide tooth side provides maximum contact on the drive side, spreading the load and extending chainring life. Narrow side allows for mud and debris clearance and reduces friction. Alternating wide/narrow tooth pattern helps prevent chain drop.
