Retaining Rings

Updated June 2025

Madrone uses 2 types of retaining rings for SRAM derailleur rebuilds, and they both work.

Type 1 requires more care during installation, and generally requires special retaining ring tools. For this reason, we are converting over to Type 2.

Your Missing Links kit might come with Type 1, Type 2, or both. There is no need to worry, all the steps are covered in detail in the installation guides in the Support Center.
