TPU Ultralight Inner Tubes NZ | Road & MTB Tubes
TPU (thermoplastic polyurethane) inner tubes are a new generation of ultralight bike inner tubes offering significant weight savings over traditional butyl rubber tubes. Increasingly popular with performance-focused road cyclists and mountain bikers, TPU tubes provide NZ cyclists with a rotational weight reduction that's genuinely felt on climbs and accelerations.
Why Choose TPU Tubes?
Dramatic Weight Savings Over Butyl Tubes
TPU inner tubes weigh as little as 35-50g compared to 100-200g for equivalent butyl rubber tubes - a weight saving of up to 150g per wheel. Rotational weight at the rim and tyre makes a disproportionate difference to climbing and acceleration, making TPU tubes a practical performance upgrade for NZ road and gravel cyclists.
Compact Packing for Emergency Spares
TPU tubes pack down incredibly small - a fraction of the size of a standard butyl tube. NZ cyclists can carry more spares in the same space, or reduce the bulk and weight of their saddle bag significantly. Perfect for minimalist riders who want to carry the bare essentials without compromising on spare tube security.
Compatible With Road, Gravel and MTB Tyres
TPU inner tubes are available in sizes covering road, gravel and mountain bike applications. Whether you're running 700c road tyres, gravel-specific sizes or 29er MTB hoops, there are TPU tube options sized for NZ cyclists' most common wheel and tyre combinations to achieve maximum weight savings.
Good Puncture Resistance and Valve Options
Modern TPU tubes offer good puncture resistance comparable to quality butyl alternatives, with the option to patch them conventionally after punctures. Available with both Presta and Schrader valves in various lengths, TPU tubes provide the right valve configuration for NZ cyclists' different rim depths and pump setups.
