I can do a stoppie on bumpy pavement an they don't bottom out. I don't remember the % static sag I went for, but I usually try for abut 20%. Of course you adjust that with the spacer length. They supply PVC pipe for making spacers.
Thanks Jim, that does help. I sent them a question regarding what spring rate I need for my bike. Waiting for the answer now but based on their charts it looks like 0.85 should be the right spring for me.
