Wolf Tooth 104 BCD Chainring 34T B Drop-Stop

104 BCD is the most commonly used bolt pattern for double and triple cranksets and was originally created by Wolf Tooth Components. This chainring is what got us started. The Drop-Stop tooth design makes it the highest-performing, longest-lasting wide/narrow chainring on the market. Compatible with 104 BCD cranksets. Drop-Stop technology. Wolf Tooth's patented Wide/Narrow chainrings allow the wide side of the teeth to have maximum contact with the drive side, distributing loads and improving chainring life. The narrow side allows for clearance of mud and debris, reducing friction. The alternating wide/narrow tooth pattern prevents chain derailment.
