    shimano hyperglide chain

    I tried a search on this topic, with no luck.

    I need to replace my chain soon...my drivetrain is dura ace 7400 6 speed freewheel.

    I have seen hyperglide HG models with various numbers after them. I imagine the higher the number, the thinner the chain...to work with the narrower cluster. But what's the real difference, and which one would work best with my standard-6 speed spacing? I am guessing I want the HG-50 but not sure.

    Doug, the numbers refer to the model of the chain not the thickness. Thickness is dictated by the number of speeds...10 speed chains are narrower then 8-speed chains. Any of the HG/IG 7/8 speed chains will work.

    50, 70 and 90 series chains differ in materials used.

    Jim,

    Thanks so much for the clarification!

    FWIIW, after doing some research, I decided on a SRAM PC-870 for about $16 (with Powerlink) for the rebuild of my old Trek 400 with 7-speed Shimano drivetrain.

    I've had no problems running Sedis or Sram on my 7400
