Some will argue the whys and wherefors of "other than traditional" wheel designs, but I saw this in the current issue of VeloNews (Vol. 30 No. 19) and was intrigued by the concept.

I know that Kevlar has been used as wheel spokes before (I remember John Tomac racing (MTB) on a Tioga "disc" wheel spoke'd with a continuous strand of Kevlar back in the early nineties... super trick and super expensive, even by today's standards, but with the somewhat fatal flaw if I remember, that if said strand broke, the entire wheel collapsed (thus a protective disc)).

What do you engineer types think? A better way to distribute stresses?

I'm also a jazz fan and like the use of the name "Django".

We abide.

Remain In Light.

Spokes are pretty light to start with, the question is how much lighter are the kevlar. The other real question of course is how much weight can you take out of the rim without getting into trouble (taking weight out of the rim is more beneficial for acceleration than hub weight). Thermal effects are a concern with carbon rims also, especially on long descents. From reviews i have read, it seems that in the past a lot of carbon wheel builders have not worked this issue. My initial response is that they are just trying to lighten up the wheels, and not necessarily distribute the loads any differently.
