Tourney v Altus

[AlBaker]

To finalize my RD situation. I looked for the Alivio 7/8 speed RD, having decided to get one. Each place I found that sells them (including Amazon) said they are out of stock and don't know when they'll be back. So, wondering why this was, I came up with an answer that could be true.

Times are hard in the US, thanks to a certain person's policies. People are having a hard time just to pay for necessities. Food and utilities are going up and up. They are now going to thrift stores instead of buying from regular stores. People are losing their jobs, thanks to AI in some cases. Businesses are not hiring as they normally would. Cars being repossessed by the thousands. Homes are being foreclosed. It's all a bit depressing. If money is tight, it might explain why cyclists are buying the cheapest RDs which are still available. Bike shops are unlikely to stock the more expensive RDs like Alivio if they can't sell them. Hence being out of stock. One year ago, things were so much better.

I have ordered an Altus.

Indeed. That Britney Spears has a lot to answer for!

I think the length of the chain is a factor more than the derailleur itself. I measured the distance from the center of the chain ring to the rear axle on both bikes. It's 3 1/4" (8.25 cm) longer on the cruiser with the Tourney, than on the bike with the Altus. So there's that much more chain flopping around, a total of 7" (18 cm).

What's the chainstay length got to do with "chain flopping around"? The chain has to be longer but the RD spring stops the flop.

Add to this ["an article that claimed the Tourney sometimes causes a clonk when changing gear"] the extra chain length flapping around because it's a cruiser, and it seems to answer the question.

Maybe you have the chain too long. This just sounds like excuses. I think we need images of the 'cruiser' showing its drivetrain.

To finalize my RD situation.

Do you have an "RD situation"? Thought it was just the "occasional" 'clunk'.

The chain is not too long. "Situation" was about the differences between two different RDs.
Go find something else to do instead of picking apart what I've said?

I'd eat bread and water for a month and save up, rather than go below 105 ! Snob... me...

It's pissing with rain and blowing here!

Wettest start to the year I can ever recall. 39 days gone, about 37 days of rain.

These two RDs are interchangeable (as indeed is @Drago's Alivio, which is the best in that bracket) and can be used with all shifters (and speed) up to road 10sp (except ST-4700s) but NB not MTB 10sp.
Your clunking and stuff is maladjustment.
Recommend Relja's article to enhance knowledge.
Rear-derailleur-compatibility
6 to 10 speed
"Rear shift ratio is 1.7, that is for 1 mm of cable pull/release, RD is moved left/right by 1.7 mm. Any 6 to 9 speed RD will work perfectly with either 6, 7, 8 or 9 speed shifter, regardless whether it’s a MTB, or road shifter, or RD. They are also compatible with Shimano 10 speed road shifters, except the Tiagra 4700 series."
@raleighnut might delete his rushed (3 minutes!) comment.

I thought they put Altus and Alivio on bikes people ride once or twice then never ride again. I don’t I’ve seen them on a bike.

A "clunk" sound is usually something that lagged a while, to then catch up in a moment.

You've obviously never used an indexed Campagnolo rear mech, you certainly know when it has shifted.
