416 stainless steel is not the first material choice for most component manufactures looking to use stainless steel (most use soft 300 series). That is because 416 is hard...hard because the raw billet is expensive, hard because it takes a long time to machine. However, that did not stop Wolf Tooth because there is no denying that it is the best material for those that need the ultimate durability in a chainring. These stainless steel chainrings are not only beautiful, but they will last 5-10 times longer than their aluminum versions.

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.
