P Zero SmarTUBE RS trims weight, adds up to 1.5W
Pirelli builds the P Zero SmarTUBE RS from TPU instead of butyl, and that material swap is worth up to 1.5 watts over the brand's own standard tube according to Pirelli's testing, a real gain at the pressures and speeds this tube is built for. The same TPU wall lets a tubeless-ready wheel and tire run this tube instead of sealant and still hit the rolling resistance numbers sealant setups post, per Pirelli's lab data. Three valve lengths, 42mm through 80mm, cover shallow and deep-section rims without forcing a valve extender into the mix. It's built to run under the P Zero Race RS tire in either TLR or tubetype form.
What Our Gearhead® Experts Are Saying:
"I run these on a 60mm rim and never touch a sealant bottle. The tube seats, holds pressure, and that's the whole maintenance routine."
