Progressive Monotube Question
I just installed a set of Progressive Monotubes and since winter is still hanging on tight around here I am unable to take it for a spin.
I do however, have a question for others that are using them; how much movement do you get when holding the front brake and pushing down on the bike while seated? I have heard folks mention no fork dive; mine seems to move an inch or so. Given my weight (170lbs) I used 1 preload clip in one fork and 2 in the other, to split the difference between too soft and too firm that seems to be a common theme.
Anyway, I'm just looking for more things to think about until I can actually ride again.

I don't have monotypes but I have had my forks apart to replace my lower sliders with chrome ones. I would have to say that if your forks didn't compress some while shifting your weight on the bike then they would be so stiff it would be miserable to ride. You should always have movement of a suspension component while trying to compress them. I think your fine.

Well that, and I'm just going stir crazy waiting for global warming to kick in.
I've never heard of that? Where did you read that? Also it seems the amount of compression you have is normal.

I think 'no fork dive' refers to a reduced amount of dive when braking. Quite obviously we need plenty of movement, or life would be darned uncomfortable! Dive under braking is partly due to poor damping and hopefully Progressive have used a better design in their monotubes than in the stock forks.

I would not install different preload on the forks. They're a pair and work as a unit. I don't see any benefit and only increased stress on the stiffer fork. Seems potentially unsafe and I'd call progressive before I rode around like that.

So as I see it, adding an additional preload spacer is nothing to worry about.

when I put mine on last year I e-mailed Progressive about the clips, wanted to know if I need 2 or 3, they told me most of the time 2 works great 1 was for extra light people that ride solo all the time (under 150 lbs) 3 was very rare bike maxed out on weight, I am 255 or so and wife is 165ish and the ride is much better and almost no dive when braking but there is still movement in the front forks when I sit on it and when I hit a bump
