Interesting timing. This past weekend I just installed Grabaruk's 10-50 cassette, front oval ring, cage and pulleys on my 2016 Transition Patrol. It replaced a 10-42t XO1 cassette.
A couple of things I learned during the install:
wide-range cassettes and their longer cages also need longer chains. This makes for a floppy, bouncy experience, which I wasn't expecting. Almost like going back to the days before clutch derailleurs.
Also, the chain needs to be longer than the old method of "full compression + 1 link" in order to get appropriate chain wrap and b-position. I had to do some digging through on-line tutorials about how to determine appropriate chain wrap and its effects on shifting, and how to set b-position. I eventually got there, but had shortened my chain too much, and had to add some links back in.
In terms of performance, it seems to shift fine. I have an XTR shifter and XT derailleur body. It definitely prefers one-click shifts, and seems to get overwhelmed by the 4-jump thumb presses. But I can live with that. I'm definitely still on the fence about the floppy chain. We'll see after this season. I need the extra range to rehab after a back injury. Once I'm back to full strength, I may go back to the older "taughter" system as I still have all the old parts packed away.
