Will be interesting to see what the Rep has to say, especially if its installer error ie. the shop ain't getting it right!! Could be a bit of embarrassment happening there!! Keep us posted...
So here is an update. Looks like the shop was able to fix the shifting issue. I would not All it 100% but around 90%, maybe little more as 10th to 11th gear shifts but sometimes it hesitates or takes bit longer. At minimum, it's shifting and even Smooth Shift is also working now.
The shop reached out to their Sram Rep and they were no help from what I can tell. Sram rep was supposed to come by but never did and kept on delaying. Supposedly sram gave the shop some advice but didn't fix the issue. I advise the shop to reach out to Forbidden as I also have reached out to them couple of times. Forbidden said it was setting issue. Shop did reach out to the Forbidden and they gave the shop some advise and looks like it worked.
Not sure exactly what they did but from what shop told me, they had to pull the derailleur further out as they were setting. Supposedly derailleur or jockey wheel was too far out or too low when shifting from 10th to 11th. As mentioned mentioned, I think it had something to do with trying to mimic sagging when setting/aligning the derailleur.
They also told me another person had to look at the jockey wheel to see how far it was out/away as they were setting or something like that.
My assumption is, when setting derailleur, you have to pull it back as much as you can or even pull back further where the jockey wheel may flex/bend (not actually bending).
I have installed T-type in the past with no issues but don't understand all the mechanics when the derailleur is pulled further out when setting.
I did hear from Forbidden that there are/were some issues with T-type and Dreadnought E but with correct setting, it will work.
Didn't realize it was such a headache.
There is no doubt Dreadnought E is an awesome bike to ride but being so sensitive to T-type, not sure if I would buy it again and have to deal with shifting issues or potential shifting issues. My main concern is for what ever reason, what if I had to realign the derailleur again? May have to take the bike to the shop again which is a big hassle. Would just rather fix/adjust myself if I can as the shop is about an hour away from me. Try 1.5 hours+ with traffic.
At end of the day, glad it's working now.
