ok...this is a long explaination, but I need some help.
did the obvious thing, converted to singlespeed because I had some spare singlepeed bits and I needed the shifters for another bike (first mistake).
on one kit - 16t and I kept my lx front chainrings, set up the chainline things were looking fine.
when trying bike out BANG! I assumed my freewheel had slipped - it was probably time to change the pawls (dt swiss onyx hub) - been there before - ordered the parts ~£6 worth and rebuilt.
great - it worked - commuted for a couple of days, but found that 16t was too much - ordered 13t cog. Chain a bit slacker but not slack enough to remove links to used a tensioner. BANG!!! oh dear...should have replaced both the pawls - not just the one that looked a little worn...
replaced the whole freewheel and pawls and retainer ~£35....BANG!!!!
oh dear - possibly not the freewheel then...put singlespeed kit on crossrides from other bike...BANG!!!!BANG!!!!SNAP!!!...
ok...so please please tell me what I'm doing wrong and how I can fix it!!!!
