Compatibility Analysis

Show Compatibility Analysis

Each click of the shifter will move the jockey by 3.83 mm on average. Manufacturers generally to target a cog pitch that is between 0.7% smaller to 6.9% larger than this number.

In practice, no groupset aligns the jockey wheel perfectly for every shift. Manufacturers generally allow the chain to make up to a 1.2° angle from the jockey wheel to the cog.

LinkGlide 9-Speed

Cog Pitch Versus Average Shift

The cog pitch of a LinkGlide 9-Speed cassette is 4.05 mm, which is 5.5% larger than the average shift. This value is within the typical range for measured groupsets.

Worst Case Misalignment

This combination with a LinkGlide 9-Speed cassette puts the chain at up to a 0.8° angle to the cog. This amounts to a sideways difference of 0.42 mm between the jockey wheel and the cog. This value is within the typical range for measured groupsets.
