can't ride wo one
misplaced the charger for my Roubaix dI2 and eventually ran out of juice (no shifting). BTD carefully explains which components you need for a recharge (it can be slightly confusing) and several days later 90 minutes-back on the road. Fortunately there were other bikes to use in the mean time.

Shimano stuff works!
I bought a nice bike 2nd hand that for some reason did not have the charger for the Di2. This fit the bill and does exactly what it is made to do. Great selection and a competitive price.
Thanks!
