3/32" halflink chain - more rigid laterally?

Posted on
  • My off road/trick 26"er has a 3/32 drive train - chainline's good but the chain 'flexes' alot laterally, and it's not slack (so you can leave your oscc's!) - are half link chains more rigid laterally?

  • does it even matter?

  • Yeah because it gives the back end a 'sloppy' feeling I'm a bit paranoind about when I'm skip stopping and hopping

  • what the hell are you talking about.

    you are saying you can feel your chain moving from side to side? er.

    the only time that i could see this being relevent would be in the split second between pedalling and the chain becoming taught from skidding. which i highly doubt you would notice anyway.

    it is probably worn if it flexes a lot side to side when you wiggle it with your fingers, whilst stationary.

  • get a campag 11 speed chain, that will be more rigid

  • I thought there was more lateral flex in road chains to aid gear changing....?

  • Why not just put a burly 1/8th chain on? I'm assuming your drive in single speed here, but if so, you can fit a 1/8th chain on 3/32 sprockets.

    :)

  • If you're chain line is straight you should not notice any lateral flex, unless you're frame is flexing a lot! I'm confused by what you say.

  • If your chain is moving laterally on a singlespeed then I would worry about loose cones and bottom bracket before worrying about the chain.

  • yes if all BB and rear bearing are tight and chain line is straight and cahinring and cog are not bent (and frame is stiff)- you might be getting loose / tight spots because of not-quite circular chainring / crank set up - is this what you're describing? -i.e. at some points in the crank's 360 degree rotation the chain is tighter than at others

    if so then get a dedicated ss/fixed crank and ring. the one off geared bike are not so precise (and incidentally have lower teeth so easier to derail) because you just wouldn't notice a slightly ovaled ring on a bike with a rear mech they aren't made so well.

    alternatively it might just be the mount of the ring on the crank spider - some aren't taht accurate- sheldon brown's site has a method to try to get the ring as central (running as circular) as you can. having said that i've had no probs ever running cranks and rings off (geared ) road bikes with 1/8 chain.

  • are half link chains more rigid laterally?

    No, but bushed chains are. It's pretty hard to find bushed chain these days, especially in 3/32, but the Wippermann 1Z1 1/8" chain is cheap, widely available, and very good. The 1G8 is even less flappy, but massive overkill if you're not doing chain grinds.

  • also, can you even get 3/32 halflink cheeeyyaaans?

  • yeah izumi make one I think. I think to be sure I'm going t change the drivetrain t 1/8" next month. Just need a 110 bcd, 1/8 chainring - 40t
