Just put on Ultegra DI2 last night... fiddled around a little but was getting late so I hit the sack.
One thing that was strange was... I was having issues shifting from 10th (smallest) to 9th... It just won't do.
Other up/down works just beautifully which has me a little stumped... (9th to 10th, 8th to 9th, 9th to 8th all works fine... and rest of range as well)
What could it be? Definitely not cable tension
Some insight would be awesome. Thank you!
Everything is spot on (Hanger/Wheel/Chain)... I think I figured out the issue.
Changing wheel did nothing, however, changing cassettes made it work just fine... I think this particular cassette either is defect (didn't bother measuring depth on caliper yet), or just incompatible with my setup. More prone to think it's bad cassette. Thanks guys.
