I know this is the last generation of Shimano Di2, but its still a great deal. BTD is great at taking your phone calls with questions about compatibility as well as stock so my entire experience has been great.

This is the first Di2 bike I have built up. BTD is a great place to get top quality products from. I highly recommend them.

Exceptionally crisp shifting. Easy to adjust. It does exactly what you want electronic shifting to do. The elimination of the low limit screw means you use shift mode for small ring adjustments.

Easy conversion from cable shifting to Di2.

Using this on a 2x gravel bike. Typical accurate Di2 reliability.
