Review on 🚴 Enhance Your Cycling Experience with SHIMANO Ultegra Di2 Grommets by Reginald Ward

Revainrating 4 out of 5

Essential for Di2 cycling

These hubs are suitable for Di2 use. They don't fit the frame perfectly, but it's better than nothing. I used some silicone gasket to make sure they didn't come out.

Pros
  • Very good value for money
Cons
  • Big and bulky
