Ok so ran XG Eagle 12 for a couple of years, I dragged to an XO1 shifter that was beautiful, very crisp, not much force required, nothing ‘abrasive’ in feel. Be bike build when Shimano for price of parts down the line. The inevitable cassette replacement. I fitted XT shifter and have adjusted the barrel and cable tension to get the optimal up and down shifts, but I find it isn’t as smooth as z I’d have liked, notchy when tuned right. So GX was bushing, X01 utilised a bearing and hence the difference in feel. Does XT and XTR have the same differences? Would I get a cleaner, lighter, less clicky, notchy shift especially from the downshift? Any advise appreciated!
