Here are some measurements I took from some of the square taper cartridge bottom brackets we carry. The drive side length is measured from the edge of the bottom bracket shell to the very end of the spindle. These measurements should be good enough relative to each other for chainline adjustment, but I wouldn’t use this chart to compare with bottom brackets from other manufacturers, which may have different taper lengths.

Thanks for taking the time to measure them!
nice tech details in the spirit of sheldon!
This page is broken, with the bb measurement info gone. Can someone fix this?
Oops. We’ll work on it! Check in later. . .
