Vittoria spent the last year researching materials and production to try and produce a new generation of lightweight inner tubes. With the bike company’s latest product, the Ultra Light Speed , it claims to have accomplished that goal.

Compared to Vittoria’s standard butyl inner tubes, the new ones are 70 percent lighter, 14 percent faster and 57 percent more resistant to punctures. If you’re worried about the environment, fear not, as these tubes are also recyclable.

Vittoria achieved its intended goal of ultra lightweight tubes through a not-so-secret ingredient called thermoplastic polyurethane, or TPU. Let’s take a closer look. Thermoplastic polyurethane

If the technical name of this material sounds vaguely familiar, that’s because it’s everywhere. Google it and you’ll get what we mean. Its extreme durability and wide applicability, which Researchgate.net briefly summarizes here , made it popular across industries and consumer products.

Vittoria clearly agrees. TPU is not only recyclable, but flexible in its uses. It’s stable from 47°C all the way up to 100°C (116°F-212°F), and retains its shape even when stretched thin, the company said.

It’s also elastic, airtight while retaining air pressure, and resistant to punctures. Even if it a cyclist does manage to puncture the tube, Vittoria maintains that it retains air longer when compared to butyl and latex.

Compared to butyl inner tubes, which usually are 1mm thick, the TPU tubes measure just 0.35mm. As a result, they can only be welded with “high frequency technology,” Vittoria said. Vittoria’s info for riders Speed freaks among cyclists may embrace […]
