Wolf Tooth 104BCD 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. This chainring started it all for us. The Drop-Stop tooth design is the best performing and longest lasting wide/narrow chainrings on the market.

Drop-Stop technology. On Wolf Tooth’s patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction.
