clubber, I've run XT/XTR for years and I find it takes a certain amount of adjustment, especially as it gets older and worn. I was never too bothered about the fiddling as it was my race bike and that of course needed a certain amount of fiddling between races anyway. The gears on this bike were stripped off last year when I did a SS conversion.
But then about 8 years ago I bought a Cannondale hardtail with Deore on it and found that to be the same. Plenty of fiddling. When that got worn I replaced it with Sram X7 and found that to be brilliant. Put it on the bike, adjust gears and ride the bike. Don't adjust gears again. Ever.
This time last year I bought a new 'dale with Sram X7/X9 on – it hasn't needed any attention at all to the gears – this morning they were all slotting in as nicely as they were last year.
However the Genesis I bought over the summer (Deore/SLX) needs to be adjusted every so often as grit gets into the system and was the bike responsible for my comment about typhoon weather – two weeks ago riding in normal Welsh rain I was reduced to about 4 random gears whenever the bike allowed it. Once I dried it off we were back to changing gears in a two down, one up style. This bike will be changed to Sram in the not too distant future.
I want my gears to work whenever I ride the bike. I don't want to spend 20 minutes every week adjusting gears. I don't care how many sprockets are in my cassette, I just want to use what's there.
I'm also suspicious about Shimano claims to be a Japanese company. As far as I'm aware Japan gets lots of rain. If so, to add to the above, why do my Shimano boots NEVER dry out. Hmmm?
