They're terrible. Like riding on 2 flat tires.


Sweet! I'm not a gram-shaver (I ride with a lead-acid battery for my headlight), but I'm curious how much weight these things add.

Any hints on where to get them? I'd love to try some out.

Looks cumbersome and a bit irritaing if you need to change our tyre.

I line the inside of my tyres with a cut down (i cut the sidewalls off), worn out slick tyre. So that effectively makes your tyre puncture proof against all but the most determined of puncture makers.
