Patented Drop-Stop® Tooth Profile
Wolf Tooth Components are the best performing and longest lasting wide/narrow chainrings on the market. We've put countless hours into designing, prototyping, and testing to come up with our new patented tooth profile. Test riders all over the world have confirmed that this design provides unparalleled performance. Here are the details of WHY it works:
Asymmetric tooth shape:
This is a close-up view of our new tooth profile. Notice that the 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:
This picture shows a top and side view of our chainring with a chain so you can see how they fit together. Notice that the right side of the tooth is as wide as we can make it to maximize the 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 we 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.
