The Wolf Tooth 107 BCD Chainring for SRAM was designed to fit the 107 BCD Spiders for SRAM cranks, with a special tooth shape that ensures a deeper valley between the teeth, perfect for accommodating the larger rollers of flat top chains.
Optimised for drop bar bikes, the Drop-Stop B profile of the teeth is narrower that the classic A profile and will work with all 9, 10 and 11 speed chains, as well as 12 speed SRAM Eagle, Campagnolo®, KMC and SRAM Flattop AXS Chains.
