How do I find out which size chain I need? I have a Schwinn Midmoor Hybrid, 21 Speed (3 front / 7 rear).

All 6, 7 & 8-speed rear gears/cassettes use the same 3/32" chain width. Chains are shipped with enough length for almost any bike. You need to cut them to length with a chain breaker tool (which you really should buy if you don't have one). Be sure to leave enough length to allow shifting into the largest front chainring and the largest rear cog/gear at the same time (even though that's not a very good gear to ride in).

I had the same problem and found out I had the wrong size chains. I needed them immediately so I had to buy from a local dealer. Amazon was great and took back the ones that did not fit. I followed the sizing instructions on Amazon website and they were still to small for my tires.

No. That said, KMC has Missing LInks for 9 speeds. You really need to find the model of your chain and look up the specs. Make sure the chain widths are the same. Even a Missing Link for 9 speed may not work if it is thinner than your chain width.

Matt, the pitch (length from pin to pin) of all derailleur chains is the same. You want to be sure the width is correct. This KMC chain is specified for 7 and 8 speed clusters and will work with the 8-speed cluster on your Trek.

Others have asked about what these chains will fit and my answer has been: Call the listed fulfiller (mine was out of Oregon) and ask them. They are super nice to deal with and have answered others who called them (I have received feedback on this :-).

Usually cassette sizes 7,8 & 9 are compatible. It's a newer bike so I think you should be fine. Remember if you decide to switch the speeds on the bike you're also going to have to switch the shifters if they are not compatible to the speed...

If the 024 or 026 are similar, the L81 if the current chain is .325 .063 or D72 for 3/8 .050.Also could check number of sprockets 7 should = 3/8 and 8 should = .325

You need to find out what pitch chain your bike takes if its a 520 pitch it wil fit providing it has the correct amount of links which determines the length.

Go to the Security Chain Company website and check the tire size chart. Look for your tire size and see what chain number they recommend. I did that and the chains that I ordered from Amazon fit perfectly.

Look on the guide bar. It will be stamped with the chain pitch and gage and length.

Search 'tire chain finder' on line, one of the web sites should be scc- tire chain finder. This will bring you to security chain's website and you can put in your tire size and they will give you the different sets that fit. Or you can just view their application PDF's.

Yes. Any Shimano or SRAM 10"speed cassette will fit. If you go beyond 28 teeth you probably should get a longer chain. 11-27 or 12-27 cassettes are pretty easy to find though.

If it is replacing the same 26"x 1.50 measurements the rear wheel it should work just fine. Make sure the rear wheel that you order is for the correct gear size. I used this wheel on a 21 speed. I needed to buy a special tool to remove the rear sprocket. A extra 4 $. Check to see who makes the rear sprocket and buy the tool made for that sprocket. Hope it helps out. I replaced my friends rear wheel from a mongoose that had been run over by a car.It was cheap and worked fine.

fixed speed bikes take the 1/2 x 1/8 chain and multi-speed bikes take the 1/2 x 3/32 chain. I believe your hybrid is a multi-speed bike, so should use the 1/2 x 3/32 chain. You may have to adjust the length you may need a chain breaker tool? Hope this helps.

Looks like the 17t runs the 1/8" chain vs the 17t 3/32 runs the 3/32" chain. Hope this helps.

You can use any size as long as you have your chain fit the size of the bar. If it don't fit the bar you can have links added or taken away.
