help me ID these mystery bottom brackets

[manbeer]

First looks to be pretty straightforward but I need to replace the bearings, second I had pulled from a random bike I had and was just curious, third is a major pain in my arse as I can't find the right tool to remove it. Non drive side lock ring came off with a normal spanner, then the drive side is odd. Even then, I don't see any way to grab the body and unscrew from the frame. Any clues? Thanks

Edit. Photos didn't upload in order. The one that has 2 pics of it is the one I really need help with. Can't figure out how to remove it for the life of me

A ha,the third is something my LBS has just managed to unscrew and replace, they had a machine shop make a tool I believe. I'm popping down tomorrow, I'll see if I can get a photo of their tool for you.

Thanks, its the weird black one mounted in the frame that looks like a reverse version of a normal bottom bracket spline pattern that's got me. Its been driving me mad

the bottom one looks like a Mavic

looks like mind you. same colour for the lock ring

Bottom one could be, its definitely not marked. Its not the weird one where you have to chamfer the shell as I have one of them too and its got beefier lockrings

Re:

Bottom I would bet is Syncros.

But what's the other side like?
Standard pin tools or full pin tool should get it out. May need a bit of acetone dribbled on the outside of the cups/frame thread to held dissolve any threadlock.


Others look like they may need this tool or similar

Re:

Think you were right on the syncros. That looks to be close to the non-cartidge version on bikepro. Good thoughts on that external BB tool as well. I will have to count the splines and if it matches up that may be the ticket. The odd think is that it looks as if that's a lock ring but I can not see anywhere to loosen the body of it. Would be a shame to destroy it in removal but I almost feel Dr vise grips will soon be making a house call. I really want to ride this frame

Re:

Can you not tap it with a screwdriver, old locknut sylee?

Re:

I suppose I can give it a try

The odd one that has the reverse splines is still a bother. Once I get them off I still see no way to remove the body. Wondering if the ends pop off

I think Cannondale made a similar tool to fit that.
