mongoose bottom bracket

(1/2) > >>

skippyg:
hi there,

   ive strip out my 87  mongoose decade ready for powderm,when I took the bottom bracket apart
on oneside it says mongoose and on the other side it has 28 stamped on it,does this mean it is
a 28tpi bottom bracket?

 my question is would it be easier to swap it for a 24tpi bottom bracket as it seems nearly all
cranks seem to be 24tpi and therefore will I can get a crank a lot easier

  many thanks for your help and opinions on this

As far as I know mongoose used 28tpi up to middle of 82 then 82 onwards changed to 24tpi.

insectbones:
And yeah, you can swap to a 24tpi no problem  :daumenhoch:

skippyg:
cheers guys,24 tpi it is then :daumenhoch:

On all the goose's I've had up to 85 all had 28tpi one piece cranks and bottom brackets.  :) Never had an 86 so cant comment on them.  :-\  By the sounds of it if yours is an 87 they were still using them then.  :)

24tpi cranks and bottom brackets are a lot easier to source.  :daumenhoch:
