Since upgrading to Shimano Di2 on my main bike, I've always wanted the same crisp shifting on my older Giant TCR. This week I picked up a DURA-ACE 9070 Di2 groupset to complete this second upgrade. The 9070 is previous generation, but still fully compatible with current generation Di2. This video is the unboxing, testing, firmware updating, and finally the Di2 diagnostics process completed with the Shimano E-Tube software.
Groupset Details:
DURA-ACE 9070 Di2
- Front and Rear Derailleurs (FD-9070 braze on / RD-9070)
- Left & Right levers (ST-9070-L / ST-9070-R)
- Front & Rear brake callipers (BR-9000 x2)
- Seat post integrated battery (SM-BTR2)
- Junction box A (SM-EW90-A)
- Junction box B (SM-JC41)
- Cables x4 (FD/RD/J-A-B/Batt)
- Plus a Remote Satellite Climbing Shifter (SW-600)
