What chain for 3 speed bike

What sort of chain do I need for a 3 speed gear bike, with a internal gear hub, I’m thinking it is a single speed chain



  • Generally you need 1/8 or single speed wide

    Measure how wide the cog teeth are. If they are over 3/32" then you must use a single speed chain (1/8"), if they are just under 3/32 you can use a multispeed (5-8 speed) chain if you prefer.
    Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.
  • Yes, you will need a single speed chain. It might be confusing because your bike have gears, however because they are placed in the hub your drivetrain is essentially single speed.
    1/2 x 1/8 is the standard single speed chain size where 1/2 is the distance between links, or pitch, of a chain and 1/8 is the width.
    Make sure that you tension the chain after replacing. I've found a good article here:
