I am interested in a CX specific boinger fork...do any of you know any manufacturers that make 700c susp. forks?

Marzocchi and White Bros both make forks designed for 700c wheels. They're intended for use on 29" MTBs which are basically heavy-duty cross bikes. No reason you couldn't but one on a cross bike though it would mess up the geometry unless you had a custom built frame.

Rockshok also made a 700c "road" fork; I'm sure they did one for caliper brakes, though they might have done one for cantilevers as well. I know there's at least one seller on Ebay who seems to have bought out a whole bunch of these that he/she was offering as NOS; I don't recall seeing them within the last couple of months, but a little searching wouldn't hurt.

I'd assume the modern Marzocchi & White Bros 29-er forks will be 1.125 steerer tubes, so if you're looking to retro-fit an existing 'cross frame that may be an issue.

Yet another option for a little compliance up front would be to track down one of the last-generation Flexstems (the sprung parallelogram ones, rather than the elastomer single-pivot version). Since most of those were quill-style (I think they did a few threadless), that might mean a switch to a threaded fork (or cutting & threading your existing steerer), if you're currently threadless. Once again, Ebay might be the ticket for one of these.

Cheers!

go white bros. if ya gotta do it...but why not just ride a MTN bike?
I assume you aren't going to race (as the weight would be murder)
You can find some NOS (Manitou and RSt cx forks) on ebay as well. If you are making this an adventure bike go with the white but it will throw the geometry off. I figure if you are going to run susoension ya might as well be on an MTB.

I have a softride stem, but the darn thing is too long and I odn't feel like messing with my saddle either to compensate for the disctance I have to stretch out on. If I use a fork, I don't have to unwrap the tape and undo my brake lever and shifter, just swap forks and whalah.

I've also looked into it and the Marzocchi Marathon is your best bet. They have the standard size steerer tube for mtn bikes and also make a 1 inch at least for now. I called Marzocchi in in so-cal and they answered some questions of mine. there are 2 versions of the fork, one with a spring/air and one with dual air.The one with the spring/air weighs a little more but it has a feature that never lets it completly lock out,giving you 30 mm no matter what.Could be useful.
As far as weight is concerned, how much more does an air fork weigh over a standard steel fork? Flip side to that of course (if you want to keep it real)how much more does a nice steel fork weigh over a carbon one? I'd rather spend the money on an air fork than a carbon one. The weight of disk brakes for a one hour race is not something i think is worth the hassle/cost but an air fork with limited travel (80mm or less) is. I'm going to try it, i pray that the geometry isn't off too bad,i'm going to measure everthing out before money changes hands.I'm sure someone can make a cx bike custom with a susp fork as the focus. I'll keep you posted.

.. makes a Headshock style fork that I've seen on some 29" mtb's - Kelly has their new Soft Shoulder cross bike designed around one - even a full suspension prototype!

The Marzocchi Marathon and White Bros CX-1 are way too long to retrofit on an existing bike designed around a, say, 400mm fork - the White Brox coming in at 475mm and the Marzocchi at 487mm (presag). That would slacken your head angle considerably, not to mention seat angle and bb height, and perhaps most importantly, put forces on the bike that it was not designed to handle, snap!

we have an elite man (took 5th in the 30-34 Masters Nats) who is sponsored by C'Dale. He race with one rigid and one headshock equipped C'Dale and pretty much dominates so it can be done. just have to make sure bike is designed for it
