The BCD 104 is the most common chainring bolt pattern on double and triple cranksets and is also the very first product ever made by Wolf Tooth Components. The Drop-Stop® tooth design is the highest performing and most durable on the market for narrow-wide chainrings. Fits any 104 BCD chainring including Ochain systems.Drop-Stop Technology. On the patented Wolf Tooth narrow-wide chainring, the wide side of the tooth has maximum contact on the drive side, which distributes load and improves chainring life. The narrow side allows for mud and debris to pass through, reducing friction.The alternating wide/narrow tooth pattern prevents chain derailment.
