    Spindle Length for New Frame!

    Please remind me how one determines the correct size bottom bracket spindle for an optimum chainline. My new frame will have the standard 73 width shell. Do I simply measure? And between what to what?
    I'm running a Paul singlespeed WORD hub (135) in the back.
    Crank: Race Face Turbine with Spot ring.

    Thanks! JK

    I'll try again. It can't just be guess work. The Sheldon Brown site had info...but not much of it made sense for the rear hub I'm going to run. Any suggestions? Thanks!

    looks like the chainline spacing is 51.5 on the hub. Check their site http://www.paulcomp.com/

    you can do some digging and find tech specs on the Race Face Turbine.

    ok i'll play.

    paul word claims to have 52mm chainline.

    from personal experience with different bb's, a spindle of 113mm will give you 47.5mm chainline if you use the middle, and 52.5mm outer spider respectively.

    so, 113mm is the closest you can get from being perfect.
    everything sucks but my vacuum cleaner.
