BB sizing

Posted on
  • hey guys i have been having problems with a wobbly BB and need to change it, a friend of mine has given me a spare one but i need to know how to size it as i am not sure if it is the correct size any help/advice appreciated
    thanks guys.

  • whats the frame? bb sizes are fairly standard, its threading that you have to look out for

  • its a mid 80s raleigh road racer not sure of a model though and the bb i got is a shimano sealed cartridge

  • should be standard English thread... bb should fit...

    or are you posting cause its not, then might be strange threading some where

  • no i havent any experience with bbs so i figured id ask before mutilating my bike and realising it dont fit i believe it has standard threading thanks a lot

  • With the right tools fitting a sealed BB is painless even compared to setting up brakes.. "Go-for-it!"
