Quality difference between Shimano Alivio and XT derailleurs (mastodon.social)

This is the reason a #Shimano XT #derailleur costs more than a Shimano Alivio. On the left you have the whole-body slop of an Alivio M3100 derailleur. On the right you have the same of an XT M8000. There's noticeable slack in all the pivot joints of the M3100. There's no noticeable slack in the XT. It feels like a single piece. The result of this difference is misshifts like going one gear higher then back to the desired one, or otherwise some shifts taking longer between gears.

There's a second video in the original post showing the XT derailleur.

One of these days I ought to start caring, and maybe upgrade from my 30-year-old 7-speed Suntour (or whatever it is).

If it works for you, there's no need to upgrade. If you ride only occasionally and mainly in flat terrain, it won't make a huge difference.

If the gearing is set up right, you can ride up mountains with old style freewheels. For 23 years I rode a mid 80s touring bike with a 13-30 six cog freewheel on the back and 28-44-48 chainrings. That kind of half step gearing gave me close ratios and only one or two duplicate gears. The bar end shifters could be operated even when I was out of the saddle.

Did a few tours in the rockies and rode it to work nearly all year 'round.
