Optimised for mountain bikes, the Wolf Tooth 104 BCD Chainring is the original that made the brand famous, with its revolutionary wide-narrow Drop-Stop tooth profile that is one of the best performing designs in reducing the threat of chain drop in 1x setups. The tooth profile is now Drop-Stop B rather than Drop-Stop A, though.
Wolf Tooth has designed the right side of the tooth to be extra wide, to ensure maximum contact with the chain, thus spreading the load over a larger area. This minimises wear on the tooth.
The left side, meanwhile, guides the chain on its passage to the chainring, but doesn't have to transmit load and is narrower than the roller pin on the chain. Since wear isn't an issue on this side of the tooth, Wolf tooth has removed material to create a channel that sheds mud. More clearance means less friction and less chance of mud causing a dropped chain.
