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
