Compatibility:
- Fits Shimano R9100-generation Dura-Ace and R8000-generation Ultegra rear derailleurs
- Fits standard derailleur hangers only
Direct mount derailleur hangers are not supported.
These are not common and the stock b-link that the RoadLink DM replaces
will not be present on bikes with a direct mount derailleur hanger
- Optimized for use with 11-36t, 11-40t, and 11-42t 11-speed cassettes
Will improve performance with 10-42t 11-speed cassettes,
but not to factory levels
- Does not change the derailleurs total chain wrap capacity.
