Know before you buy
104 BCD refers to the Bolt Circle Diameter, which is the measurement between the mounting holes on your crank spider. If your current crankset uses a 104 BCD bolt pattern, this chainring will bolt directly onto it without needing an adapter.
No, this chainring is specifically engineered for 1x (single-ring) setups. It lacks the shift ramps and pins required for front derailleurs to move the chain between rings.
Drop-Stop B features a specialized tooth profile that alternates between wide and narrow widths to match the inner links of your chain. This tight fit prevents the chain from bouncing off during rough descents or technical riding.
This chainring is compatible with most 9, 10, 11, and 12-speed chains, including SRAM Eagle and KMC. However, it is not compatible with Shimano 12-speed HG+ chains, which require a specific tooth profile.
In most cases, no. The Drop-Stop B technology is designed to provide enough chain retention to eliminate the need for a chain guide on single-ring setups, even on aggressive terrain.
