Rear Derailleur Replacment
Hello,
My rear derailleur broke and I am looking for replacement.
It's old Shimano Alivio RD-M410.
I am thinking to replace it with new Shimano Alivio RD-M3100 which looks a bit difference and wonder if it will match.
Another alternative I found is the Shimano Alivio RD-T4000 which looks very similar but is rated for trekking.
It's for an 7X3 speed diamondback recoil.
Hope someone can help me with this one.
Thanks

Either will work 7 speed stuff is quite old school and if it is more modern I would be careful putting money towards it as the 7 speed era was in the late 80s early 90s.

If you're a casual rider, even a Tourney level would suffice.
The thing NOT to do is 'upgrade" too much.
As you increase the number of speeds, the cage etc. gets slightly narrower each step, making things more finicky when there is no need.
Keep it to a 7/8 speed max.

I can attest to that. A Tourney TX ($13 new at LBS) made a fine replacement for the Dahon compact rear derailleur (replacement would have been $80!!), the Tourney worked much better. Box said 6 speed (in hand sharpie) but worked great on my 7 speed. Mine is a GS (mid) length cage. The TX also comes in direct mount, or a claw mount for those without a rear derailleur hanger, like my folder.

The Tourney would probably work fine, but honestly you will get such higher quality and better shifting springing just a few bucks more for Alivio.

The reason why new Tourneys work so well for 6s/7s is because of better modern manufacturing that was more difficult 25 years ago.
I've installed new $5 Sunrace RD's that worked flawllessly.
6s/7s bikes aren't serious and Tourney is fine.
I would recommend a premium RD where is is required and noticable, 8s and up.

7 speed is still common.
Newer 9 speed derailleurs are not finicky or have special dimensions that are problematic with 6/7/8 speed chains.

My only suggestion is to get a long cage RD. I don’t know what freewheel?/cassette? you are using, but if you are running a 28t large cog, get an RD that will go to 34t.
If you ever want to change you are able. And if you are already running a 34t you’ll need it anyway.

I don't know where you guys get this stuff from. The Tourneys of 30 years ago also indexed just fine. Indexing is not difficult with Hyperglide type cogs.
7 speed is still common.
Newer 9 speed derailleurs are not finicky or have special dimensions that are problematic with 6/7/8 speed chains.

Tourney of a long time ago was much better you look at the 70s-80s era stuff it was metal construction most of the derailleurs were better. I get people love to say tourney is good, it isn't. It is better than a sharp stick in the eye but most things are better than that. It can work in mediocrity but it isn't good stuff and we know this. If you are a very occasional rider and you can keep it tuned it can work but let's not try and make it better than it is.

I get it from factual information of when 7 speed components came out and where they are now. They started at Dura Ace and XT and are now at the absolute bottom
