Light(ish)weight Pompetamine

Just to clarify, the rims are tubeless ready, not tubular. You'd still use clincher tyres. Benefits other than weight include potentially better rolling resistance and ride quality, and the ability to run lower pressures for more grip off-road with less chance of punctures as there's no tube to pinch. Self-sealing properties for small punctures is a bonus aswell.

iower - thanks, all clear. My tyre tech' knowledge is about 30 years out of date!
