I realize this is the road forum, but this seems to be a MTB/triathlon mix.

Wow, an all purpose bike, you can use it as a road bike, MTB and Time Trial bike. Just like a cheap multi tool, promises to do everything but does nothing well.

Triathlon extensions can also be found on my mountainbike.
They are really nice for longer training rides in the winter when there is snow etc..

Looks exactly like a Trek Y Foil

There is even a picture out there with one and the 4 spoke wheels.

Its funny I had the Y Foil and as cool as it looked the non flexing carbon frame just about rattled my shoulders apart, terrible concept....

The main cool thing about this thing is how the frame is made. The Lexus works utilize a 3-d braider instead of laying up sheets of carbon fiber.

I can see staggering weight weenie implications using this new generation of manufacturing technology...

I for one would like to see someone TT down a MTB trail.

That's essentially the same process as the Impec (Link Link), which from what I recall turned out to be a rather porky frame. Also this and this.

I'm no engineer, but I can't see how this process wouldn't create a lot of excess/redundant material compared to traditional layups (e.g. if you need a few layers for impact protection on the top and bottom of the chainstay, how would this weaving process not add additional material to the inside and outside as well?)

Layup is actuall very cool because it's so easy to mix and match different cloth to achieve the desired result. Braiding, won't be so easy, you can't just seamlessly slip a section of M60J into the threads. Maybe that's why the Impec uses lugs... I am still not convinced by braiding, other than the cool visual effect of the machine at work.

I like the way those handlebars are mounted, never seen it done that way before.
Could be interesting to get low on 29'rs
