Hello Gentlemen

Just wondering what are the thoughts on the amount of preload on the front forks of 180 degree bikes with 38mm forks.

Is 15mm sufficient?

Thanks,

John
 
Hi John,

I think it was Lothar (LaverdaLothar) who covered this really well in a thread on suspension 2-3 months ago.

I sorted my errant Mirage by trimming the preload spacer until I had about 40-50mm (can't actually remember now) of sag in the forks when sat on the bike. Prior to that I also took out the springs, collapsed the tubes down and filled with oil (10wt) until there was 150mm of gap to the top of the tube ( I think this needs to be quite precise and not 'roughly') . I then extended the fork out to full length, replaced the spring and the trimmed preload spacer, and refitted the fork: lovely.

Anyway, that was the gist of it. I'm sure someone will provide a link to the correct thread and response presently
