    Going from 120mm bb to 113mm or 110mm bb: Help

    my bike had an older cup and cone bb; 68 x120 dimensions.

    should i be okay going to a cartridge bb with either 68 x 113 or 110?

    First determine what crank you are going to use, before trying to choose at BB spindle type and length.

    already have the crankset, square spindle sugino m type off an old road bike. i had used it before, but i needed a larger chainring and the bb was getting rough. the bb will be the shimano bb-un54

    What was the chainline like with the 120mm BB? Losing 7mm may be a bit of an issue if it was straight with a 120.

    There's no reason to waste money, do some research and find out what length spindle the cranks call for.
