would it be possible to create a fixed or ss full suspension bike?

I think you would need a bike with no chain pull whatsoever. It would have to either be a unified rear triangle design, where the BB is mounted on the rear triangle, behind the pivot, or with a GT iDrive, where the pivot point is concentric to the BB.

Yeah, if the distance between the rear cog and BB changes at all, it won't work for fixed.

SS is do-able with a tensioner probably. Still, I'd feel a little uncomfortable.

slingshot is gearing up to make single speed versions of their farmboy model I think.

The Kona Cowan DS can be set up as SS (and I presume fixed) as the main pivot surrounds the BB & the chainstay length doesn't change at all during suspension travel. Same for a couple of the Cove bikes (hooker?)

I know a bloke that used a XO derailler cage as tensioner on his SS Yeti ASR.

The cove is the G-Spot, I have been meaning to take mine out as a ss for awhile now. Not as intended but I needed to rig my bighit up as a SS to get off a mountain once when I lost a pulley halfway down, it was definitely an interesting ride!

they also made (make?) 26" SSers, but i've only ever come across 3, and they were all the same size, and all for sale, so for all i know, it could just be the same bike over and over.

also, checked out that link, looks like he's using an eno hub, so it's probably not something they're going to market.

ok thank you all for the replies. i spoke with the owner of my lbs and he said its possible and thats what got me interested in the subject. i'm going to look into it more and try to afford one of these gems.

WTF? Double drive? I want it.

Speaking from experience, these things are bob city. Avoid!

I really wonder how the last Mad Max bike would ride.

I would expect double drive to be a bad idea, seems like if it threw one chain the whole thing would kind of rip itself apart.
