I am looking to replace a Shimano Altus, 8-speed, will this derallieur work?

As a direct replacement its unlikely you could get it to shift properly the 10 speed dyna sys derailleurs are only designed for use with 10 speed shifters. In my case (9speed) this required a new 10 speed cassette,chain and shifter. 8 speed should be the same unless you have an older thread on style rear hub. To me the clutch on the derailleur makes it worth it and you could lower the cost by using slx instead of xt on some/all of the components.

Okay, so it's not the model of the bicycle, it is the compatibility of the components that work together. So yes, if you have 3 chain rings in the front and 7 cassette or freewheel cogs in the rear, most likely it will work. However, there are other factors: derailleur (the mechanism that reacts to the pull or push of the shift pod to change "gears") ratio (Shimano is about 2:1 units in the shift mechanism, so you need a derailleur that has the same 2:1 pin/rivet/bolt unit ratio), or something in need of replacement or readjustment.

I don't know -- but the Alex R450 is compatible with 8-speed Shimano cassettes. I am using it with a 7-speed cassette and a spacer.

The box states it will, I have only installed it on 7 speed bikes, but my impression is should work fine on a 8 speed also. Easy to install once you use a chain tool to get it at the correct length

The cassette should work on any Shimano or SRAM hub. As far as I know, all Shimano hubs, mountain or road, use the same 'mounting pattern' for cassettes.

I think it depends on your cassette. It's meant for 9-speed cassettes. On Shimano's website, it's listed under the mountain bike parts. The Shimano road bike derailleurs are the Dura-Ace, Ultegra, 105, Tiagra, Sora, 2300 and 2200 series.

It should in the same cage length. I'd contact SRAM. They have been pretty good about replacing failed derailleurs.

It should adjust to fit BUT a lot depends upon your shifters, cables etc.... If you have thumb shifters I think it will work. I have seen a 7 speed Shimano click shifter work but of course it had to be adjusted to fit...I use new 6 speed twist shifters and cables when I work on a bike. For this job the time the old derailleurs will work most of the time.. It's not a big difference going from 5 to 6 speed but I don't think 7 is worth the trouble... I have stopped using this particular cassette and now use the 34 teeth low speed since our local area has some big hills......Good luck..

It works with a Shimano Altus Rear Derailleur that I replaced through WalMart online 3 years ago. My bike is a Specialized Hardrock mountain bike.

I would think this should work on 7-speed. You just don't trigger it to the 8th gear.

Hi. It should. This is for the 6-7-8 speed HG50 7.3 mm chain. I had bought this for 8 speed applications but Shimano gears and spacing for this group is almost identical or the same so the same chain is used for all. I have found the specs given by KMC quick links to be accurate for both Shimano and Campagnolo BUT read carefully what you are actually getting before buying.

I'm not sure about he SIS but I would think so. I don't know the model of my front derailleur but it has two gears as my bike is a 14 speed and it worked great for me.

I believe it will. All Shimano (and Sram) hubs and cassettes use the same groove pattern.

If you have Tourney shifters with a 7 speeds rear derailer and 3 speed front derailer you should be fine. The most difficult part is fine tuning the cable length nuts to get the shifters just right.

As long as they are both 8 speed. So if you have a 8 speed cassette and and 8 speed derailuer than a sram 8 speed shifter will work.

I don't know. I matched this item to my bike. It is not identical to the factory derailer, but works great. Match as close as you can is my only suggestion.

What you have is actually an 8 speed (3x8). The ST-070 will not work for you.Ileana
