Thanks for the quick response (including the email!!). This is very frustrating and IMHO very dumb, can we petition Shimano?? I asked SRAM some time ago but they think simple is better, frustrating.

Thanks Barry. Also for your call earlier. I will see the type of the hub once I am able to remove the cassette as so far my screwdriver/hammer approach resulted only in few cuts on my hands. It's properly stuck there. I would love like to claim that the shifted casette is a the result of my super legs power and the wattage going through the pedals but somehow think that the answer is different.

I had a very similar issue with my Di2. Shifting from 11 to 10 would often fail and would just "click-click-click". This was the only gear giving me any issues at all. I would have to shift to 9 and then up to 10 to use my 10th gear. After struggling with this for 2-3 months I finally found out my B screw was the problem. Set that correctly and the problem went away completely. I now have perfect shifting to all gears again.
Therefore, I would check your B-Screw. There is a tool you can use but I set it by doing this:
Therefore, I would check your B-Screw. There is a tool you can use but I set it by doing this:
- With the bike on a stand put the front in the smallest ring and the rear also in the smallest ring (yes, it will be a cross chain config)
- Unscrew the B-screw to the point where the chain is touching the frame
- Slowly start turning the B-screw until the chain becomes taught.
- You should now be very close to having the B-screw set properly. Give it a test ride and if you still have trouble try turning it a quarter turn in either direction until it is smooth again.
