PLEASE NOTE: We can't assist you in choosing which length of square tapered bottom bracket you'd require. Choosing the right length is determined by trial, not from anything that can be gleaned from tech specs. Every bike and setup is different, making it necessary for the buyer to purchase a bottom bracket lenth that best meets their exact application. Variables are numerous - chain stay shape and cutout, how far the arms slide onto the spindle, front derailleur travel, etc that we cannot account for. Ideally, you want a bottom bracket that's long enough for the inner chainring to clear the chainstay, while not extending it out beyond where the front derailleur can travel.
