## Customer Reviews

### ⭐⭐⭐ 







  
  
    Tough install, not sure about it.
  

*by N***K on Reviewed in the United States on August 18, 2019*

Bought for my gravel bike, running XT di2. Definitely and advanced install, but do-able (needed to find the manual on Shimano’s site, google “DM-M8050-08-ENG”). Had to change my chain length and mess with the b screw/limits to keep it from rubbing. It’s all aluminum, so should be durable. If I hate it I’ll lower my review. So far I’m not really sure if it’s worth it.
