It Worked! 11-34 with 105 GS (longer cage) Rear Derailleur. - B Screw Fix?
Swapped out cassette to a 11-34 with a 105GS and Durace Bar Ends. Worked with no adjustments. Indexing is fine.
The only issue I ran into is the B Screw does not engage the tab on the frame. I picked up a 4x25mm B Screw thinking I would need it. Discovered the existing B Screw did not engage the tab and using the 25mm offered no improvement. Took the original and flipped it and it barely engaged the tab. The cage / upper pully has 2-3mm clearance from the 34t cog.
Is there a way to bend the tab the B Screw is threaded to so it will engage?
Edit:
After some research I guess I can get a 4mm self locking nut and put on B Screw to increase size to contact the tab on the hanger. This is on a Jamis Aurora Elite - Jamis missed the spec's here for sure.
