104 BCD Chainring

104 BCD is the most common bolt pattern on double and triple cranksets and happens to be the first product ever made by Wolf Tooth Components. The Drop-Stop® tooth design is the best-performing and longest-lasting wide/narrow chainring on the market. Available in multiple tooth profiles for optimal performance based on your chain type. Use Drop-Stop ST for use with Shimano 12-speed Hyperglide+ and 12spd KMC chains. Use Drop-Stop A for all 9, 10, and 11spd chains or 12spd SRAM Eagle, KMC, Connex or Wippermann chains. Drop-Stop B is optimized for SRAM 12-speed Transmission (T-type) and Road Flattop chains but is compatible with all chains that work with Drop-Stop A. Fits any 104 BCD crankset. Drop-Stop technology.

The narrow side allows clearance for mud and debris, which reduces friction. Alternating wide/narrow tooth patt
