    How do I now if I need a bigger spring (Nixon fork)

    I've been on my new 05 Reign for just over a month now and I think I need to order the bigger spring for the Nixon fork. I have been messing with the compression and rebound adjustments, but no matter what I do when I'm out of the saddle cranking hard I get 3 to 4 inches of dive on my front end.

    That is too much, right? I have worked on my body position and smoothing out my pedal strokes and can at time reduce it, but mostly it just dives until I sit my ass back down on the seat.

    I'm 6'2" and 215 lbs and thought I might need to upgrade to the bigger spring - any thoughts?
    Thanks

    I'm 200 and had to buy the Firm spring for my aftermarket Nixon. And I still bottom it when I land small jumps wrong.

    You should use at least the firm spring, probably the extra firm spring, kit to avoid bottoming. The spring costs $20. But to remove the left side top-cap it requires a custom machined or ground-down thin-wall 28mm socket (six-point) that a bike shop is very unlikely to have. Manitou sells a thin-wall socket they make for $32. Or you can grind down a normal wall thickness $12, 28mm (six-point) yourself.

    Before even buying a firmer spring you could try changing your right side damper oil to about 10 or 15 wt fork oil to firm up damping and slow dive, but it will make it more harsh over bumps. T

    It will never be a really firm pedaling fork without custom internal valving work by an expert shock tuner.

    I would guess that you need at least the firm spring, if not the extra firm spring. I've got the same bike and I weigh 210-215 lbs. I bought the extra firm spring and am much happier with it. I like the rear end set up rather firm and with the stock spring the bike was very unbalanced. If you're going to order it, do it ASAP because mine took months to get here.

    Don't dick around, at 215lbs you need an x-tra firm.

    I'm 180lbs w/gear and moved up to a firm which I think I still could bottom out w/o a major type hit.

    Climbing out of the saddle is now marginally better.

    Got an x-firm coming my way

    I talked to my LBS today and they will be ordering me the x-firm kit in the AM from their distributor. Should have it all dialed in by the time I go to Whistler in mid-August. Thanks for all the responses. I knew this might be an issue when I got into the bike, but I wanted to be sure that was the fix needed.

    It will cost me $24 for the kit. That doesn't seem expensive to me in comparison the everything else. I'm also upgrading the front rotor to 8" - sweet!
    Thanks
