Stringbike drivetrain - Adapatability to Cruzbike frame?

[TriPop51]

1. Has anyone thought about useing the Stringbike drive-train technology on a Cruzbike frame? (http://www.stringbike.com)

2. Idealy I would love to see the fusion of synergy from the Cruzbike recumbent technology with the vertually maintenance free drive-train technology of the Stringbike.

3. Airless/Tubless/Spokeless Tire - Anyone know of such a thing? I find tires to be the greatest wekness in biking as I always have tire issues every year. Usually having to replace a tire or tube due to damage or wear. It would be wonderfull not to have to ever worry about tires again, especially on long rides of 20 miles or more as is the case for my regular rides.

4. Oh, and has anyone thought about "BABMBOO" for the frame?

Just a dreamer looking to meld the best biking technology in to one great ride.

Shalom my friends!

Finally I found a video of the system.

If it could be retrofitted to a regular bike, I suppose it could be retrofitted to Quest, or Sofrider. But not to Silvio (flexing chainstay is incompatible) or Vendetta (chainstay connection to BB bearings is incompatible.

Timing is important, if you just bolt it up, you might get the dead spot management occuring in the wrong place. See my elliptical chainring guide as a reference to this issue: http://cruzbike.com/adjusting-elliptical-or-ovoid-chainwheels. As I read it, the timing adjustment step on string bike is 90 degrees. For e-rings as a comparison, timing adjustment steps are needed at more like 6 degrees. Could be a showstopper, unless the stubs for the cranks are inserted on a spline or domething that could be exploited for greater timing adjustment ... but then, this would alter the effective crank length.

My advice, just get on a cruzbike and capitalise on that benefit, then think where you want to improve matters.

Chains - I don't regard them as high maintenance. Out the front where they stay clean, I get reather long service life.

Tires - I am not a specialist here

Bamboo - good for flooring, but no real environmental benefit for bikes as the rest of the frame, vast majority, is still the same stuff. Sure, its possible. Lots of things are possible.

Airless tires suck, suck,

Airless tires suck, suck, suck. Hard to install, heavy, and the rolling resistance is ridiculous. I tested them on only one of the two tires on my Rans Rocket and couldn't believe how hard it was to keep moving. Even worse than a generator light... or two.
As for the bamboo, not so much, but hickory bikes were made ove 100 years ago. See the link
