    My SS chain wont fit!!! please HELP!!

    Hi

    Ive started building my first jumps bike and the wheels come with ss cog on it and ive got a new chain for it but it wont fit, it ends up being either to short or if i put another link on its to long so do i need to get a chain tensioner or something to sort it out??????

    Thanks very much

    If you don't have horizontal dropouts, sliding dropouts, frame with EBB, Trickstuff Exzentriker, ENO Eccentric, ghost ring or magic gear, you'll need a tensioner, yes.
    Ride more!

    go to your LBS and get a 'half link' first. if that still doesn't work, then you'll probably need a tensioner.

    try a different chain, I couldn't get an 8 spd chain to work (either too long or too short) on my 1x1 but a SS specific works fine....at least with the ratio I'm running

    Surly frames have sliding drop outs thats why you dont have any problems. I suggest a non spring loaded tensioner. When I ran a SS I had both a half link and a Tensioner and I preferred the tensioner.

    sette makes a nice tensioner, no springs to screw up. or make your own, which isn't hard. just google it.

    Okay, you made me look. How could the width of a chain have anything to do with the length? an 8 speed chain has links 3/32" wide and 1/2 inch from pin to pin (adjustments can be made in 1 inch increments). A SS specific chain has links 1/8" wide, but has the same 1/2 inch from pin to pin. unless you have a half link or a half link chain (a chain made entirely of half links) there is no way a SS (1/8") chain can be made shorter or longer than an 8 sp chain.
    Just one more rep and I get the toaster!

    Dude, i was as confused as you are I'm not sure what was going on but here's what happened: I've been running a Sram PC-1 on another SS bike with a tensioner and when I built this 1x1 I just moved the chain over to it. The chain was a bit old so I decided to throw a new chain on there for a trip i was taking so I bought another PC-1, bc I like that chain and have never had any problems with it, but I also bought an 8 spd chain bc alot of guys on here swear by em and I wanted to try it out. So, i go to put the 8 spd on first and make it the same length as the old PC-1....but for some reason it's too short, it wont even connect together even with the hub all the way forward in the dropouts.....easy fix right, add a link...but then it's so long that as I pull my wheel back in the dropouts the brake rotor hits the bottom of the caliper before the chain gets tight! So after standing there looking at it for 15 min or so wondering if I'm the stupid one or it's the chain I pull out the new PC-1, cut it dwn, put it on and it works fine, just like the old PC-1. I dunno what was going on or why the PC-1 works and the 8 spd doesn't.....it's strange to me too!!!

    I think you misread my post....I actually DID have problems with the 8 spd chain vs. the SS specific chain. See my response to akabrad below for the explanation

    I did miss read it when I replied. But it is racking my head why it doesnt work. If you count the links do they come out the same at the same length? I would just stick with the SS specific chain. They are much thicker and stronger than a normal geared bike chain.

    Thicker, yes, but not stronger. The width of a chain has nothing to do with it's strength. Most bike chains will have around 3,300 lbs force until they fail, and the generally superior steel and heat treatment in multispeed chains makes they longer lasting.

    HaHa, I am NOW racking MY brain as to why it doesn't work either. At the time I just needed to get it together so I didn't put much thought into it but now after this thread I'm going to go back and see what the hell the deal is!! They SHOULD fit the same, length wise that is.....

    Maybe it has a Gusset made cog. See my frankenbike roadblock thread for details.

    Dunno what cog the OP is running but mine is a Surly...saw your thread, sounds like you just have to run 1/8 chains on their cogs. Both my ring & cog are 3/32 so the 8 spd chain mates with the teeth just fine but thats not really the issue at hand....at least not in this thread.
