PC 850, 830, 870, 890 - they all say they work with an 8-speed drive train. What's the difference? Will all of these work with my bike?

I'm using the PC-850 on a 7-speed Shimano cluster. SRAM says they are all compatible with an 8-speed cluster and that the pricier ones last longer. All but the PC-850 are also said to be 9-speed compatible. http://www.sram.com/sram/road/component/chains

I recommend doing some reading. Short answer is they allow for different big big and small small gear combinations. Look here for a good explanation. http://forums.mtbr.com/drivetrain-shifters-derailleurs-cranks/when-use-long-cage-vs-short-cage-derailleur-205890.html Figure out what gears you plan on running up front and in back and then choose the appropriate cage per manufacture recommendation. I hope this helps

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

Yes,it will accept shimano 8,9,and10 speed cassettes.If your cassette is Hyperglide C,you will need a 1 mm spacer to make it work.

Yes it will work just fine. My Harley is around 850 and it has no issues at all.

Nearly postive that it won't. I tend to believe most all 10 speed componets are just specific to 10 speed since their chain is thinner than a 9 speed. I do know a 9 speed crankset will work with an 8 speed and vice versa. Ask (google) Sheldon Brown

it depends if you have a 3 sprocket cassette on the front by the pedals and a 7 sprocket cassette on the rear wheel. if not then no these will not work. you also need to have shimano deraileurs. its the part that moves the chain to switch gears at the sprockets.

Hello Gustavo, Yes they will definitely fit, with no problems. You may need a new cassette and 2 spacers. I believe that your Trek 850 is a 7 speed if i am not mistaken; If it's a 7 speed you might need 2 spacers. The great thing about these wheels is that they come with 2 free spacers. These wheels are number 1 sellers here in my store and are the best upgrade can you do for your bike. Hope this helps

I currently have this on my 8-speed bike with no problems. I purchased this along with an 8-speed chain and an 8-speed cassette (chain and cassette were made by SRAM). I'm very satisfied with it.

Hi,You will need to purchase a 5 speed shifter. Because these are specified as seven speed (rear). A 5 speed shifter will only work with a 5 speed cassette.Thank you.

The only real difference between a 10-speed crankset and a 9 is the 10 has the middle and inner chain rings moved over very slightly to the right to make them work smoother with the narrower chains. In practice if you are using an older 9-speed crank with a 10-speed cassette/chain you should notice very little problems unless you are out of sequence (meaning you are shifting down in the back a few times before you shift down in the front,etc, if you are not sure what I am talking about take some time to look it up because you can very badly impact your cassette/chain/crank life when using the wrong gear combinations). Might not be perfect but it should almost definitely work.

I second the comment that cassettes for 7, 8, and 9 are compatible usually on the same hub. Your derailleur and shifters will determine how many of the gears in the cassette will be used.

According to the package it will work on 7 and 8 speed derailleur chains. It does not differentiate between companies. I carry it but haven't had to use it yet

Don't know, can tell you this though. I bought two and both are out of commission. Cheap build, didn't last one trip. Go with Shimano or Penn

... ciao: first, these are NOT specific to a 9-speed rear deraileur, as they given as replacement for the X7 8-speed component. i would suggest you research the SRAM website for definitive information. in my research, it seems there are both new and old models with the 'same' identifier, but 'different' capabilities. SO, failing that, locally, they are said to work. your mileage may vary.

Number of speeds is not important. What is important is that it is compatible with the width of your bottom bracket.

No this is designed for shimano or sram cassettes only. This will work with 8 through 10 speed cassettes I think a 7 speed will work but needs a spacer.
