Recently upgraded my Gen 1 Levo to a 2020 Gen 2. My SRAM PG-1130, 11-speed, 11-42t cassette is showing wear and I'm now having moderate ghost shifting I can't micro adjust out with cable barrel adjustment. May also have a slightly bent derailer even after truing the derailer hanger. Thinking about upgrading to 12 speed so I can change to AXS due to thumb arthritis, have been using SRAM grip shifters for years. Know I will need to change free hub to SRAM XD. Can anyone give me a link to the current one to order- there seems to be multiple to choose from? Still have the stock Roval hubs. I'm fairly comfortable doing my own wrenching, have built my last few bikes from frame only(easier to hide the actual true cost from the wife, she does the same thing with her clothes purchases by paying half cash and half credit card).
