If you have a question about suspension and you want the correct answer don't waste your time arguing , just ask Gary. He has proven to be a wealth of information on the subject. It's all in his head and all you have to do is ask.
Agreed! I suspect that both of us are correct in some fashion or another. Perhaps I am confusing Compression RATE with Compression LOAD.
I just refer back to the rear shocks and how one makes them more resistant to compression and that is the pre-load ring at the bottom. Allows for more load to compress
From experience, however, we have for years done the extra tube at the top of fork springs to help against front sagging or bottoming out. Has worked.
I agree however that the best solution is to purchase new springs if old have worn out and allow more sag.
What bothers me in this whole scenario, is that the question started because a fairly light guy (160 Lbs?) was having the forks bottom out. That puzzles me. I am around 200 Lbs. and I have never had front forks bottom out or coil bind. Except on race bikes where I came down head first on the front wheel!
Seems that there might be another problem than just fork oil quantity or fork spring. Fork springs last a long time and for one to go bad would be highly unlikely.
