Product Description Ideal for Cyclocross: the 110 BCD Asymmetric 4-Bolt Shimano chainrings by Wolf Tooth Components Wolf Tooth was one of the first manufacturers to release Cyclocross-specific 1x chainrings, because they saw this as a perfect application for the Wolf Tooth Drop-Stop® technology. These beautifully crafted 4-arm chainrings for a 110 mm asymmetric bolt circle diameter have been optimised for Shimano 1-speed CX, road and gravel drivetrains, whether you ride Dura-Ace 9000, Ultegra 6800, 105 5800 or Tiagra 4700. They also have an offset to create the ideal 1-speed chainline.

For very muddy conditions a chain guide in combination with clutch rear derailleur is recommended.Technology:Drop-Stop® 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.
