First post, couldn’t find with quick search. I’ve recently swapped to larger tires, which required me to move the wheel all the way back in the horizontal dropouts. This has made the lateral distance between my derailleur pulley and cassette too much to shift properly.

Deraileuer is GX 10sp long cage. It’s particularly bad at the extreme ends of the cassette. I backed the b tension out all the way to see if it would get slightly closer, but it didn’t do much if anything for shift performance. Wondering if I can make it work with current equipment or if there is a parts solution to work with the wheel being so far back. Really want to run these tires. Thank you!
