456, E-13 and HTII BB

I took this lot apart to swap the BB over, and on putting it back together the front mech (which I didn't move) doesn't line up with the rings properly anymore. I suspect I've cocked the spacers up despite being careful to count them off from both sides.

Anyone know exactly how it should go? I think I've got, from NDS

Cup -> Frame > Spacer -> E-13 -> Cup

If it's a 73mm shell, then ditch the DS spacer as the backplate replaces it.

Hmm – according to On-One, it's a 68mm shell which means you should have a spacer on either side plus the backplate…. this won't change your chainline, only your NDS crank positioning.

Either the web info is wrong and it's a 73mm shell, or it was set-up wrong previously….

456 is 68mm for sure. sillyoldman has it right.

Actually, there may be a spacer on the NDS also.

Do you get different sized spacers?

2 spacers on the drive side, 1 on the non drive side,

or

1 spacer on each side + chain device

or

if its ISCG (Summer season frames?) then you need 2 spacers as the chain guide is on the frame not the BB.

No, it's a standard DN6 456

I'll have a play about with it. Are BB shells different sizes? It wasn't a Shimano one that came off
