"trials Rim-disc Brake. The "risc" Brake"

[Tomm]

Yes, but I thought to stop a wheel bending you need material in the plane of bending? For a wheel, to prevent side-to-side bending you need a good area of the flat bit (I.e. where the spokes meet it). Adding another disk parallel to the wheel won't help this. In fact I don't think the disc would stop the rim bending at all. I could actually see it making things worse because you'd have a weird force from the brake twisting the rim slightly every time you braked. Still, I'm willing to be proven wrong!

I was thinking of it in terms of how to get the rim to bend away from the non-disc side, you'd have to bend the disc that way too, to get it to bend, and similarly bending it towards the disc side, you'd have to bend the disc too? Bearing in mind it's a pretty strong disc bolted in place at 10 points around the rim, it wouldn't have much give in it?

I dunno, that was how I was looking at it, and from his testing it seems to work OK...

Knowing OTN their replies will be entirely sarcastic with the ultimate aim of financially ruining the foreign guy who isn't in on the 'joke'

Fair enough, they seem like a bit of a strange bunch over the pond- don't usually hold back on their true thoughts...
