Wolf Tooth Components 64 BCD Chainring

Wolf Tooth Components 64 BCD chainring - with universal matching holes

The Wolf Tooth Components 64 BCD chainring is a perfect solution for using a crank with 104/64 mm bolt circle diameter or a Shimano XT 11-speed or SLX crank with 96/64 mm bolt circle diameter for less than 30 teeth. The chainring has 4 arms and a bolt circle diameter of 64 mm, but as a " universal model" it has a special hole pattern. Therefore it fits symmetrically (104/64) as well as asymmetrically (96/64) constructed mounts. Drop-Stop® technology boasts a wide-narrow design with improved chain retention, more even load distribution for a longer service life and optimised self-cleaning.

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.
