I had a hard time getting a 700# spring (why?), ended up getting a Manitou spring at 2.25" that works just fine BUT it was wider than the standard spacers (between ft/rr frame components and linkage plates) on my frame would allow so got some longer bolts and some M8 stainless steel washers and away I go.

Roco setup is 25% sag, set w/rebound wound out and TST in DS position, BO chamber at 180 PSI (minimum), running setup is with rebound two clicks slower than centered and TST switch "wherever", coil is 700x2.25 (rider == 225# and bike has 3:1 leverage ratio). Bike is built for 2" stroke shock, but my Roco is 2.25, so I have added 1/8" spacer after the BO bumper to limit stroke, and replaced the end-cap from the BO chamber with a smaller cap (to protect the valve) that provides about 4-5mm more safe travel for the rear linkage area.

66SL1 setup is 25% sag, compression centered + 1 slower, rebound centered, 47 psi SFA, 100 psi PAR, 0 psi RC2.

Bike feels way balanced. Flats, climbs, drops, ledges up, ledges down, drops of up to 3' hit so far and all looks good. I had originally run PAR at about 85 PSI but there was one or two places where on a sharp v-notch g-out I could bottom the fork so I upped it to 100 psi and all is good.

Bear, if you can bottom out that fork, you're doing

better than the rest of us. I am actually thinking of replacing mine with a Totem if Zoke can't fix the bottom out and get me more than 160mm of travel. Are you in Austin? I live in San Antonio.

I am in Austin.

What's your body weight and fork setup, ?

I posted mine.

It wasn't off a jump/drop, it was a fairly harsh square-edge g-out (e.g. V-notch style) doing a sharp transition from downhill to uphill, up here on Thumper trail. If I have the PAR at 85 PSI it bottomed, at 165mm max travel. Next time I hit Thumper I'll take my shock pump and do some experiments at full extension.

First couple weeks I had the fork I ran it full-extension, and according to my zip tie I was able to get within 4 mm of bottoming out on stuff fairly easily, especially at City Park. I had started out with pretty low pressures in the PAR and SFA (and I've never put anything into the RC2 side).

I've seen so many people posting here about having that kind of problem, I wonder if zoke designed it so much for "extreme-FR" that it's just not going to bottom when properly setup and not dropped 40'?
