    SR Apex BB spindle length

    I have a Raleigh Super Course lacking a bottom bracket and would like to get one. Sheldons database doesn't have SR cranks on it, so I'm wondering what the right spindle length would be for the SR Apex double crank set? Is there an easy way to figure it out? I wish I had the old one....

    Thanks for the help if you got it.

    Can anyone give me a ride from Monterey to Big Bear on Wednesday or Thursday?

    Get (borrow) something that will go in the bike and mount the crank. Then measure the resulting chainline and calculate the needed spindle length. There's practically no way to know what is needed without doing some precision measuring on the crank.
    Stupidity got us into this mess - why can't it get us out?

    Hello Tradtimbo,

    It's a while ago, but did you find a suitable BB for your SR Apex crankset?

    Greetz,

    better plan .. if you are thinking about the conversion to a current UN typeBB

    the rt side length as it was is valuable data ..
