    Sugino Super Mighty crankarms....

    i've recently gotten these and they are 144 bcd. It is a road crankset, but I was wondering if anyone knew what would be a good bb length (or good bb in general) to use to get a straight chainline with the chainring on the outside of the circle?
    any help would be appreciated

    I have the same crankset, Super Mighty, 165mm, 144 BCD.

    They're also ISO taper, not JIS.

    I'm using a Campy AC-S 111mm BB, good quality and top price. This put a 42mm chainline at the dead centre of the two rings, so mine's only off by a couple mm. I guess a 107/109mm ISO would be perfect, but you have to but Record to get that in Campy.

    Edit:
    Miche $23.50
    Campy SC-S $16.99
    Campy AC-H $27.99

    It's cheap too.

    Well the Miche is ISO, and *my* super mightys are ISO, and my Campy ISO 111mm BB is only a couple of mm out, so a 107 mm should be all good.

    But I would suggest you compare a known JIS/ISO crank to yours on a known spindle and see how far each of them slide on. Eg ISO cranks won't slide onto a JIS spindle as far as a JIS crank would. All shimano is JIS AFAIK.

    hey Bikeage what spindle length did you end up getting? I ask because i have the same cranks going on an Italian frame and i cant find the suggested 107/109 spindles.
