Hi,



The silicone type is actually a fine cable protector anyhow: light, thin, frame friendly, much less obvious to the eye than any other you can buy and easily cut to any length too.

Ciao,

Not sure of the grade of stainless on that brake spiral, but I suspect it will rust pretty quickly. Could do the same with aluminum spiraled housing, but rupturing might be a concern.

Someone used to offer aluminum wound brake housing a long time ago. Never heard of rupturing, don't think it's a problem with coiled housing, only linear strand shift housing. People did complain it was too squishy, though.
If the outer diameter was not a limitation, I think all brake housing would be made of linear strands covered with something tough. this is what Yokozuna does, Jagwire offers some covers theirs with a braided Kevlar or other stuff. But all these suffer from extra friction, the liner is too close to the cable diameter. and they're a bit bigger than the standard 5mm, making some fitments awkward at best.

CLB made alloy cable housing many years ago.

Hi,

Currently there are Transfil (FR) and Fasi (Niro Glide) (DE) offering aluminium based outer cable systems too.

Ciao,
