Wolf Tooth Components 104 BCD Stainless Steel Chainring

Beautiful and extremely durable: the 104 BCD stainless steel chainrings by Wolf Tooth Components

Stainless steel 416 is usually not used by component manufacturers who want to use stainless steel (usually the softer 300 series is used). Because 416 is not so easily accessible, firstly because the raw material is expensive, secondly because it takes a long time to machine. Still, Wolf Tooth didn't let that stop them. There is simply no getting around the fact that 416 stainless steel is the best material for anyone who needs the ultimate durable chainring. Wolf Tooth's stainless steel chainrings are therefore not only beautiful, they also last 5 to 10 times longer than aluminium chainrings.

Technology:

Drop-Stop® A
Wolf Tooth has invested countless hours in the design, prototyping and testing of their Wide-Narrow chainrings and has developed a highly innovative tooth profile. Test riders around the world have confirmed that this design brings unparalleled performance.
The right side of the chainring tooth has a different shape than the left side. The right side transmits the power to the chain and the left side opens a free space for cleaning mud and dirt. Since the two sides have completely different functions, it makes sense to design them differently, true to the motto: extra reinforcement where you need it, less material where you don't.
The right side of the Drop-Stop tooth is as wide as possible to distribute the load over a larger area, which also minimises wear. The left side of the Drop-Stop tooth helps to guide the chain, but it does not transmit any load. Therefore the left side is narrower than the chain roller. Wear is not an issue on this side, so Wolf Tooth was able to save material and create a better mud clearance channel. More free space means less friction and less change of the chain being dropped due to mud.
In the A version, the original version of Drop-Stop, the profile is optimized for use on mountain bikes. The wide teeth are slightly wider than Drop-Stop B. The outer sides of the narrow and wide teeth guide the chain.
