Notes: 6 mm chainring bolts required (stock 2x bolts will not work). SRAM Exogram cranksets with inset nut must use stock fifth bolt + spacer(s). The Force CX1 bolt features fifth bolt with 1X specific shoulder.
The chain may contact the spider arm slightly when using the 38 t chainring (filing a small chamfer on the spider arm may help).
Use of a clutch-type rear derailleur is recommended. If you plan to ride in very muddy conditions, Wolf Tooth recommends a chainguide or chainkeeper in addition to a clutch-type rear derailleur.
Wolf Tooth has put countless hours into designing, prototyping, and testing to come up with their innovative new tooth profile. Test riders all over the world have confirmed that this design provides unparalleled performance. Here are the details of WHY it works: Notice that right side of the tooth has a very different shape than the left side. The right side of the tooth transmits force to the chain and the left side provides clearance for mud and debris. Since they have completely different functions it makes sense that they are designed differently. Extra strength where you need it, less material where you don't.
Notice that the right side of the tooth is as wide as Wolf Tooth can make it to maximize amount of area in contact. More area in contact means the load is spread over a larger area which in turn minimizes wear on the tooth. The left side of the tooth helps to guide the chain as it meshes with the chainring but it does not have to transmit any load. The left side of the tooth is narrower than the roller pin on the chain. Wear is not a concern on this side of the tooth so Wolf Tooth removed extra material to create a channel for mud to flow away. More clearance means less friction and less chance of mud causing a dropped chain.
