So with a little play developing in my BB, I have decided to replace the BB on my RC200 F5.
I have got the old one out, and it is a Shimano BB UN72. I thought i might be able to replace it with a new one, but of course being an old bike, they are no longer available it seems! :facepalm: :roll:
Any ideas which will be the best BB to fit? the UN72 is quite heavy, so I'm wondering if there is something lighter which will fit - the Pace manual for the F6 recommends Hope or Royce, though I'm not sure if the dimensions for the F6 are the same as the F5. I can't find any documentation for the F5.
Anyway, it's a square taper spindle, 122.5mm long, and it needs to work with Middleburn RS2 cranks. 68mm shell width.
The only one out there which would seem to fit is the UN55, though at 8 quid I'm worried it could be a bit naff.
Any suggestions?
