Finished installing my Gold Valves this week, and as part of the process of rebuilding (replacing all wear parts) in my front forks, I checked the sag before, increased the length of the preload spacer, and checked it afterward.
First, I want to thank everyone who I pestered with questions - on the phone, and via PM's. And anyone who commented in my other threads about this project. You were all a great help! The project turned out to be a success (see my Review of the Gold Valves).
I weigh right around 170# with ATG. Before sag was measured at 49mm. After increasing the preload spacer 1/2" my sag ended up at 38mm. In other threads, sag of 36 to 40mm is considered optimum so I hit the nail on the head - thanks to dduelin's formula of about 1.2 x desired reduction in sag. It worked - the formula said to increase my spacer 13 mm so I did 1/2 inch. Right on the money!
Only problem (and this is tongue in cheek) is the bike now rides a bit higher than before exacerbating touching down at stops. I couldn't flat foot the bike before, now it's a bit worse at off camber stops.
