Alivio 410

I want to replace my cheap rear derailleur.
Currently have a 2014 Giant escape 3. Came with tourney tx55 rear derailleur. 3x7 speed.

Will an alivio 410 sgs rear derailleur work? I see this in Amazon. Thanks

What are your issues with the Tourney rear derailleur? IMO, Alivio won't be a noticeable upgrade.

The reason I asked is because usually the derailleur and shifters are a matched set. If it doesn't shift well, you'll probably benefit from an upgrade in both the rear derailleur and the shifter.

Personally, I HATE, HATE, HATE bad shifting... mushiness on the shifter, ghost shifts, slow shifting, etc. Even with new cables/housing and a perfect tune, I find cheap components very distracting on rides.

I had a Costco bike that had bottom end components. I hated that bike (impersonating Superman over the bars on that bike didn't help). Then I got lucky and bought with my first real mountain bike (used) with Deore LX components and kept upgrading from there.

What until you try XT and XTR components... What a difference.

Sometimes mis-shift. But otherwise OK. I was thinking the same thing. If it won't be a noticeable difference unless I go up to deore, I may just wait. Thanks for the feedback.

Personally, I don't think it would be a bad plan to upgrade. The Tourney derailleurs really have nothing going for them other than being dirt cheap, which doesn't really help the consumer much. I don't really like any of the derailleurs with the large pulleys, but 7 speed doesn't leave many options.

I will say that the Alivio 410 crank I have has given me years of service under hard abuse, so if the rest of the group is of the same standard then it will be a good piece.

What shifters do you have?

my experience has been
that the cheap shimano parts work almost the same as the expensive parts
when new
but they start to feel old
and become harder to keep in adjustment
much faster
so my advice is
since your bike is pretty new
leave your tourney derailleur on until it tells you it needs replacing
as you will notice little or no difference at this point
regardless of what derailleur you buy

An additional note: I'm about to re-build and ride a 90's Rockhopper and make it my go-to rigid for fire roads. Although I haven't paid attention, I'm sure there are bottom end components on it. I'm not even going to bother with the shifters. I'm switching those over to Suntour friction Power Thumb shifters. For fire road rides, going friction would alleviate a lot of grief.

What shifters do you have?
I also have a tourney 7 speed shifter for rear and 3 speed shifter for front. Exact model not sure but accdg to website it's EF40 Shimano. So if I replace the RD with the Alivio 410, it should work right without having to change anything else?

DRIVETRAIN
Shifters Shimano EF40
Front Derailleur Shimano Tourney
Rear Derailleur Shimano Tourney
Brakes Tektro, linear pull
Brake Levers Shimano EF40
Cassette Shimano TZ31 14x34, 7-speed
Chain KMC Z51
Crankset Shimano M131, 28/38/48
Bottom Bracket Sealed

IMHO I'm disappointed in Giant for using a Tourney level derailer as this is typically used on Wally World type bikes.
In my opinion, the Alivio derailer you're looking at will be a significant upgrade from the Tourney. Consider that Shimano has Acera and Altus level between Tourney and Alivio and Alivio is one level from Deore which has usually been considered a good level. The design of the latest Alivio resembles the XT from a few years back and that was one really good derailer.
However, take into account that upgrading the derailer is only one part of the drive train. As was pointed out above, the shifters can cause poor shifting as can the cables and cable housing. BTW, some of the Tourney level derailers in the past were absolute crap. There was one part plastic, part metal that couldn't hold a tune-up. I came across two that broke where the metal and plastic were joined. I don't think Shimano makes that one any more, at least I hope not.
