Evil Bottom Brackets....

Hi guys,

I writing here with the hope of finding someone who tell me exactly which tool I need to buy to remove this two BB.

I have a hook kind of tool and is useless as it seems is going to break or damage the inserts where it fits.

for the one in the red frame:

+

For the other one i don't know

A C-spanner and a hammer, or something heavy. Check the direction of the threads first on Sheldon Brown. Oh, and HTFU.

is the lock ring steel of some kind of ally? most are steel. sometimes on dutch bikes they're plastic and you have to go to someone with the correct dutch bike tool, but it doesn't look like it's the case here.

tapping the hook bb tool with a rubber or wood mallet often does it. the hammer and screw driver meathod does work but it will damage the lock ring inserts the more you do it. i use that as i last option.

good luck...

Cheers everyone!

Just make sure you have checked and double checked the lockring thread direction before you start smashing at it with cold chisel and hammer. That 1st one looks like you might be better off with a big adjustable spanner. If you have access to a vice, even better. Just grab the flats in the jaws, then you can rotate the frame to get lots of leverage. That's my favourite method.

If all else fails (as it has once for me) you can VERY carefully use a dremel to cut through most of the lockring and then it will just snap off when you hit it with the chisel.
