Hi Guys,

I have a Fixie and i am usually quite good with bikes. Been having issues with my BB (Bottom Bracket) which i believe is the bearings. the issue is when i took the Cranks off i had never seen a bottom bracket shell like this
With two slits in it. what kind of bottom bracket is this? i cannot post URL's on here yet as i do not have enough posts but if i can try and explain. it has two slits or holes instead of the standard Bottom bracket.

Do i need to use a Peg spanner to get this off? (tried with many tools with no success)

I dont want to go to halfords and get ripped off (They do a shoddy job anyway)

Be nice to see if anyone has any help for me .

Thanks in advance,

M

We need way more information to even begin to make suggestions. Can you find a picture of one of these on line and post the link? You could post the URL of the link even if you can't post the URL of a photo.

Are you referring to the shell, which is part of the frame, or the cups, which thread into the shell and hold the bearings? I suspect you mean "cups."

Do the "slots" in the cup look like this?



If so, the Park HCW-11 is the proper tool for these. People do use a hammer and punch instead, but if you do, be careful. If you bugger the slots you're in for a world of hurt getting the cup out.

Yes this is it!. it is really stiff and been trying to use a hammer and flat head screw driver but this hasnt worked.

What you have is an adjustable cup-and-cone style bottom bracket, which was the standard for many decades until cartridges became popular in the '90s. You'll still find cup-and-cone bottom brackets on a lot of bikes, especially at lower price points.

Be sure to remove the outer lockring first, then attempt to unscrew the cup. They can be tight, so use care to keep from damaging the lockring too much. (If you're not using the proper tool, you probably will damage it a little bit.)

And to be sure, the lockring and adjustable cup are removed by turning them counter-clockwise. On the drive side of the bike, the fixed cup is reverse-threaded, so it's removed by turning clockwise. (Unless we're working with an Italian or French bottom bracket, in which case the cups on both sides of the bike are removed by turning counter-clockwise.)
