There have been similar systems for 4x4 trucks for 10+ years they were used as a beadlock to keep the tire on, but allow single digit pressures. They are a pain to install, but do work well for the application. It should be viable in MTB if done correctly, it should be a similar effect to the old T.H.E. Eliminator rims.

Yup, but without a vacuum setup I couldn't get enough compression. In test parts that I made, I found I could only compress 2 layers with the tape method that I used before there were bunching issues during the wrapping. The next frame will make use of a Vacuum system to allow for more layers at once and less epoxy.

I used fabrics from Soller Composites ( http://www.sollercomposites.com/ )
The top and bottom layers were 3K 2x2 Twill 220GSM 640Ksi
The mid layers were 4in and 8 in wide Uniderictional 305gsm 711Ksi,
I alternated the direction of the uni fabric. No Vacuum, one or two layers at a time with tape compression. The 4" travel enduro frame I am building this winter will have a combination of tape and vacuum compression.

For this one I did just tape wrap, but will start to work with vac-bagging the new frame I will build this winter.

I have been riding it since around April '13. No durability issues, delam, or cracks. I have done XC rides and a bit of Dual Slalom racing on it. I am guessing that I have 1.5 to 2 times the amount of carbon I actually need in the frame. When I was building it, after I put the chainstays on, but before the seat stays were on, I was riding it around the basement without any issues.

Yup, handmade in my basement. The only metal parts are the headtube, BB and cores for the dropouts. Other than that, it is all hand laid carbon fiber over a foam core. Took about a month to lay up; add a layer, set the compression wrap, wait overnight for cure, repeat.
