(1/2) > >>

staple123:
i have a sugino 1 piece which is getting rare but i want to save it, can anybody repair the thread on it ir knows how to'thanks

DR VINOAH:
how far gone is the thread?

staple123:
two little threads that is all the rest is perfect!any help? :-\

DR VINOAH:
the 2 that are shot
are they on the exposed part?

ie when the whole crank is assenbled on bike
you have a couple of threads showing

if so

i suggest a fine file set
be a tad easy with the filling
you dont really wanna lose much of it
coz you still need the nuts to do up tight

staple123:
yeah , opposite the chainwheel side??if so thats it and i will try that now!cheers
