Wolf Tooth Components 110 BCD Asymmetric 4-arm GRX chainring - for Gravel use

The Wolf Tooth Components 110 BCD Asymmetric 4-Arm Chainring for Shimano GRX is compatible with all cranks of the Shimano GRX Gravel line. It features the patented Drop-Stop® design, which provides better chain retention, dirt repellency and less wear. The Wolf Tooth GRX chainrings have four arms and an asymmetric bolt circle diameter of 110 mm. Thanks to a revised tooth profile they are also compatible with SRAM Flattop chains. They can also be used with other 9, 10, 11 and 12-speed chains, but not with Shimano Hyperglide+ 12-speed chains.

Technology:

Drop-Stop® B
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 B version, the drop-stop profile is optimised for use on wheels with drop bars. The teeth are slightly narrower and the valleys between the teeth are deeper to accommodate the larger rollers of SRAM Flattop chains. The outer sides of the narrow and wide teeth touch the chain to guide it.
