The Bio Composite Race Bicycle : Part 2

Continued from Part 1.

So hows the bike made?

This is what Bicyclingreviews have to say about the frame design. An excerpt :
"The tubes on the MF-1 either 40% to 50% Flax or 100% 3K Carbon HM and are connected with the use of lugs this isn't the smoothest way, but it gives a very strong bond between the tubes and give great stiffness to the frame. The top tube slopes slightly from head to seat, not too much, but enough to help handling and stiffness. The head tube is bulky which keeps the frame stiff and cuts down on torsion stress, the seat stays are of a wishbone design and the seat tube has an aero profile. The MF-1 is strong and light, everything you need from a bike frame, it's not cheap, but a frame of this quality is never going to be a give away."
A Luxurious lugged design

Another review from Cycling weekly can be found here, and it talks about the bike, components, wheels and ride quality.

So the frame is a bunch of tubes combining both carbon with fiber, produced by a patented high temperature and pressure process, and these tubes are bonded to form a frame using a special purpose glue. The same patented process seems to be used in cigarette papers for improved ash characteristics!

Flax-Carbon Forks

While the promised properties of the bicycle have to be really quantified and compared to existing designs to get a feel for its advantages, I look at the bike and say, 'That's one badass!' The colors are great and Museeuw is really looking to do things a little different. Thats great for the industry. If this is a viable solution, we'll see others jump into the equation and start using fibers for frames.

Whether he'll be successful in making people believe in it is another question. Currently, these frames (MF-1) are about 5600 dollars (2900 pounds or do) a piece (just the frame!). This itself discourages the widespread use of something "green".

My opinions :

1. Marketing babble or not ? I think its not a bad idea but more quantifiable, third party reviews are left to be desired at this stage. Its a great innovation though. Something that bothers me as I write this is the justification for replacing some carbon fiber for flax fiber. We haven't seen any drastic reductions to cost, and while the idea of a bio hybrid bicycle is nice, I still don't see why carbon fiber, having probably the highest strength to weight ratio is to be tweaked further through flax incorporation. If it is to make a better, more comfortable bicycle, were we really fooled to the fact that carbon bikes aren't comfortabe enough? I don't have a carbon bike, so maybe a few of you can tell me what is on your mind. According to the Lion himself :

“A 100 per cent carbon bike doesn’t absorb the shock and vibration inherent in top level bikes. The less vibration you can deliver – thanks to the combination of carbon with flax – means greater comfort for the rider."

This opinion differs among so many people. For years, carbon has known to give plush rides and vibration absorbing properties. Hmmm...

2. IF Design Awards ? Many websites claim that the design sweeped the top prize in the IF Product Design Award for 2008 in the Product Design/Leisure Category, beating 3000 entries from 35 countries, I have not noticed any such awards for the bicycle in the IF website. I may be wrong but if one of you want to check and correct me by clicking on the previous link, go ahead.

Cool , I've not heard of such a composite show but I figure they must show all kinds of sports products and such..

I hope the EFBe gets hold on one of these and pounds it with some loads to see how it performs.
