Double-sided Timing Belt?

Is a timing belt allowed. I know the directions say a flexible woven, braided, or twisted strands but is a timing belt within those parameters?

Re: Double-sided Timing Belt?

I'd ask the Q&A, as the rules are written currently my opinion is that it would be legal as the most timing belts contain strands of braided kevlar with a nitrile or urethane outer layer. This is close enough to the way synthetic ropes are made if you consider the outer layer a "strand".

Re: Double-sided Timing Belt?

The outer rubber would certainly not be considered a braided or woven fiber. But, QandA it.
You'll probably get a null answer.

i doubt this would be legal, actually, as the "coating" which happens to have a tooth shape is beyond the last 4 inches of rope. The rule says "entirely" made of fibers/filaments/strands, not just that it contains them.

The coating is flexible and being a plastic doesn't necessarily negate it from being a legal strand as a synthetic rope is also a plastic and they don't specify the size of the strands. It really depends on your interpretation. Anyway I expect the Q&A to clear a lot of this up (I'd bet the answer is no)

...consist entirely of flexible, non-metallic fibers twisted, tied, woven, or braided together except for the last 4 in. (~10 cm) of each end which may be whipped, fused, covered in heat shrink or tape, or dipped in a coating material to prevent fraying.
A timing belt does not consist entirely of fibers. You could get into argument that technically a polymer is a mass of twisted "fibers" of molecules, but since we're dealing with the macroscopic scale here I would expect that to be a "no".

I'm more interested in whether or not they clarify whether or not "width" actually means "diameter" and thus throws out webbing or Velcro methods.

The manual showed strapping though. That would be a more severe change than usual.
