MB Grand record, i think '75....owned since new (i'm old) crank arms frozen post-rebuild...just worn out
original BB, TA crank 3 pin (replaced long ago). french or swiss fixed cup? i've overhauled it 10-15 times but its been 10 yrs + and I forget... (i'm old....)
trying to go sealed BB vs cup/cone.
thanks nice to be here
