can anyone explain simply how fork preload effects the handling of the bike only i dont tent to use it at all really on the new berg in fact i normally have no spacers with in the fork after a service
Just doing the final tweaks on my forks and like cypher says really, the preload comes into play after you have the right springs for fine tuning.
As far as handling and preload(for the front) there is no guidelines, just whatever feels good to you.
Basically, more preload means the front sits higher which makes the bike turn slower.
Less preload means the front sits lower, making it turn quicker.
