Fox Fork 3 Position

You cant use the 3 position with anything other than the lever.
I took my cable off when taking the fork off and found that it is sprung to prevent turning by hand. You need the cable to move it round. I expect the 2 position will be the same set up.

Thanks. Question is more around whether a 3 position lever will make a fork that has a 2 position lever on it a 3 position fork?

Most likely a two position fork has a damper set up such that is open or closed with no graduation in between, a bit like a light switch.
Your three position switch might align with two of those or none of those.
Best result would be you have open and closed and an empty position in between. probably you'll find you've not enough movement to switch the damper between any of the modes and you'll have three positions of identically open.

You might get lucky and find that the damper works on a continuous sweep it's simply got two detents so your three positions will at least translate to more, middling and less open. I doubt it though.

Thanks. Makes sense. Will keep an eye out for a 3 pos. Cheers.

What fork are you looking at?
I'm pretty sure a grip damper will work as defined by the forks top cap and lever combo with however many position you want. Whilst the lever top cap has indents, it's compression is not defined by anything other than those indent stops. That's how Scott calls it the "grip 3"
Fit4 damper didn't come as a 2pos lever and there's no lever option at all for a grip2
According to my local fox race mechanic, the grip damper is actually better for compression variation at remote positions between lock and open than the fit4 damper as the fit is actually very sensitive to top cap position in the levers mid point

Fox did however change their fit4 top cap design and now remote forks aren't as simple to swap to lever forks as there missing the ident spring recess in the top cap.
Should be fine doing from lever to remote though.

Rockshox etc? Dunno.
