68 vs 73 Bottom Bracket Question
Is it possible to put a bottom bracket meant for a 73 mm bottom bracket
shell into a shell meant for a 68mm shell with the requisite 5mm of spacers? I know physically it would be possible, but do you run into structural and/or safety concerns (not to mention the wider Q factor). Thanks. LR |

Yes!, but you mean a 2.5mm spacer (2.5mm on each side = 5mm) If the bottom bracket has a shoulder on the drive side, you only need one 2.5mm spacer (Some bottom brackets ship with a spacer, so you can use them for 68 or 73) - No shoulder means 2.5 mm of threads showing on each side. I know physically it would be possible, but do you run into structural and/or safety concerns (not to mention the wider Q factor). Done it many time before. Only the body is 5mm longer. Spindle is the same length, same Q. -n |
