nope, it is not the XL, it had 165mm travel. I extended it myself.

I suppose yes, the design is like a typical shim stack with flexible shims opening and closing different paths in the head of the damping rod (top rod, leftmost end), but uses only a single shim if i remember correctly. Doesn't look like a shim stack design but it is.

F1 wet one, from 2001 I think.

I would like to make more, but I'm studying for a masters degree in Engineering and just haven't found the time for it lately. The front-center is 685mm. I've only made one size so far, but it seems to fit all. It's fairly long at the front giving sufficient legroom, but the short chainstays still makes it feel short and agile, so nobody has requested another size. A custom frame would be about 6000 SEK, but time is an issue there aswell so I'm not absolutely shure I could accept...

The chainstays are quite short, yes. And it will still clear a 2.3" tyre at 360mm and a 2.5" at about 365mm. Don't remember the top-tube length, I didn't bother printing it on the webpage (www.risberg-racing.st) since top-tube length is a rather poor way of defining the length of a frame. The front-center is a better measurement. If you really want to know I can find out the t-t length aswell, but there are no new frames currently for sale. The only way of getting one now is a custom order or a used one...

Damn, you sure make them thick and strong. I'm pretty much the opposite, make them so thin everybody thinks it's gonna break right away...

ah, I see you're already using lasercut parts. Forget what I said earlier then :P Interesting design with all the sharp edges and corners.

looks nice
