Ok so I was looking into the amount of sag that a street bike should have. I have done this before for my XC bikes, but I felt that the numbers will be completely different between dirt and street.
Everything that I have found so far as been between 20 and 40mm of sag for both front and rear. 25mm being for track use and 30+mm for street use. Now we cant adjust the sag that easily in the front end, it requires cutting the spacer or making a new spacer to lift it up.
The rear would require simply chaing the preload settings (1-7) on the shock.
So for those that have done this, what preload rates are you guys running? Preload settings in the rear is not what I am looking for. As I just found out, our springs rates can vary a good deal depending on how much use and abuse has been put on them. Looking for solids measurments in mm. Also besure for the rear end to clairify where you were taking your measurements from.
Back to the front end.
Lets say the bike is 5mm to high ( too much preload) Would this solution be cured by simply cutting 5mm off the spacer? Would that spacer make a direct change? If the bike had too much sag, a new spacer would have to be made. So what would be a good material to use for this spacer. Mild steel, stainless, 6061 Aluminum? I have the ability here at school to make nice clean cuts with a large horizontal saw, so this would not be tough. I just want to get some feed back before I start hacking.
Also, I realize that adjustments will need to be made for two up riding as well. If need be, I could make a seperate set of spacers for two up riding since they are very easy to instal and can be done while the forks are on the bike.
Input, thoughts?
