Wolf Tooth 104 BCD ChainringPropelling you across the forest with power and poise, this brilliant component uses Wolf Tooth's patented Drop Stop tooth design. This technology enables it to be classed as one of the best-performing and longest-lasting wide/narrow chainrings on the market. It works by using its wide side to maintain maximum contact with the drive side which spreads the loads and improves chainring life. Also, its narrow side allows for excellent mud and debris clearance which reduces friction. Compatibility:Fits any 104 BCD cranksetChainring Bolts: All tooth sizes require 1x bolts that are 6mm long with exception to 30t rings which are threaded and require bolts that are 7-10mm long.
