Bottom Bracket Cup, Non Drive, Sticking Out?

[hugh_b]

Currently building up a new hydroxx lt frame. I fitted a trial tech bb today, put drive side in first and then put non drive side cup in.

However this cup has about 3-4mm of thread still showing when fully tightened. It appears that the lip on the cup is pressed firmly up against the non drive side bearing. I always thought this cup should fit pretty much flush with the bb shell when fully tightened?

Anyone?

Mine does it too, and most BBs I've used tend to have a little amount sticking out. I think the only one I've used that hasn't was the Try-All ISIS BB - shouldn't be a problem

- Fits both 68mm and 73mm shell widths, but designed primarily for 68mm shell frames. With a 68mm shell the left hand cup will sit proud of the BB shell on your frame around 2.5mm, or disappear inside the frame 2.5mm with a 73mm shell frame.

Thanks for that, didn't see that bit in the description :$

However if you fit it in a 73mm bb shell you will be disappointed the offset of the cranks goes to shit.

i have a simlar problem also

my question is.....

is it better to have the removable side of the bb sticking out or the side which forms the main part of the bb, i sidehop to the left so was thinking to have the right side slightly outwards to protect the threads on the left (because they will be fully inside the shell)

is this a good idea or should the main body of the bb be fully wound it?

thanks

^^^^^^^^^^^^^^^

To be honest I cant see what you are worrying about.

Just make sure it is tight, even if you smash the threads, which is v unlikely they don't need to screw in anyway?

I superpose this is the case anyway.
