Spanish BB Length
Bunky:
"BMX standards" is like an oxymoron... each standard is created by whatever company created whatever design first, and then a bunch of companies take it and mess with it.
Austin Tasseltine:
if the tube spaces isnt long enough, you just have to put an extra thin spacer or two between the bearings with it. its a bit fiddly, you can either tape it to the tube spacer or put one bearing into the frame, put your crank axle a little way into the bb, then put the spacer and tube on, then put the second bearing in.
you can get away with not running the tube if you have powerbites or other pinchbolt cranks, but you probably should if you can
nailbomb:
yeap, did exactly that with the new bb but instead i installed a 1mm thick spacer in the frame cause the tube spacer is at 50mm and bearings are 18mm for both, my frame bb length is 68mm, so my non drive side bearing sticks out a lil (not even noticeable), tighten them up as tight as i could and it still spins really smoothly, my previous problem was definately a tube spacer issue, glad everything is sorted now!
Hairfarmer:
Better to have too much spacer than not enough.

Sprocket can come loose doing that
