HOWTO: Chain and Sprockets replacement

[darrsi]

Yep it's definitely still there .Just had a look at my upgraded nut and I can count 5 or 6 threads in it,so if this finishes flush with the end of the shaft when fitted,that must mean the original nut has approx. 3 threads?.

I'm not sure exactly, but it certainly wouldn't appear to be enough for the job that it is doing in my opinion.
