Who it's for: road riders still on butyl inner tubes, deciding whether TPU is a real upgrade or a nice spare.
Short answer: for most riders on standard butyl tubes, a mid-weight TPU tube (roughly 30 to 40g) looks like a worthwhile upgrade. In Bicycle Rolling Resistance's drum test, the better TPU tubes rolled about 1.4 to 3 watts per tire faster at 80 psi than typical 100g butyl tubes, at around a third of the weight. Latex is still slightly faster in the lab. The catches are cost, fussier repairs, and some brands ruling out rim brakes.
TPU (thermoplastic polyurethane) tubes have gone from curiosity to a common spare since Schwalbe's Aerothan arrived in 2020, per BikeRadar. They fold very small and weigh little. The claim worth checking is that they roll faster than butyl, because that is what separates a nice spare from a sensible upgrade.
What the lab says: Bicycle Rolling Resistance
Bicycle Rolling Resistance (BRR) tested 18 TPU tubes alongside butyl and latex tubes, each inside three 25mm road tires (Continental Grand Prix 5000, Vittoria Corsa G+ 2.0 and Michelin Power Time Trial), and averaged the results. The test ran at 29 km/h with a 42.5 kg wheel load. (Bicycle Rolling Resistance)
A selection of BRR's averaged figures, rolling resistance per tire:
| Tube | Type | Weight | 80 psi | 60 psi |
|---|---|---|---|---|
| Vittoria Latex 25/28 | Latex | 80g | 10.8 W | 12.9 W |
| Pirelli P Zero SmarTube RS | TPU | 35g | 10.9 W | 13.0 W |
| Revoloop Ultra | TPU | 25g | 11.0 W | 13.1 W |
| Continental ContiTPU | TPU | 36g | 11.2 W | 13.5 W |
| Vittoria Ultra Light Speed | TPU | 30g | 11.2 W | 13.5 W |
| Schwalbe Aerothan | TPU | 43g | 11.6 W | 13.9 W |
| Continental Race 28 Light | Butyl | 75g | 11.6 W | 14.0 W |
| Continental Race 28 | Butyl | 102g | 12.6 W | 15.1 W |
| FOSS Tube | TPU | 99g | 13.6 W | 16.6 W |
| Schwalbe SV15 | Butyl | 105g | 14.0 W | 17.1 W |

What stands out:
- Against a standard butyl tube, the gain is real. The ContiTPU is 1.4 W per tire faster than the Race 28 at 80 psi, and 2.8 W faster than the Schwalbe SV15. Two tires, double it.
- Against light butyl, it is small. The Aerothan and the Race 28 Light tie at 80 psi. BRR still prefers the roughly 40g TPU tubes over light butyl, as they "are lighter, roll faster, and air retention should be at least equal or better."
- Not all TPU is equal. The heaviest TPU tube in the test, the 99g FOSS, rolled slower than the Race 28 butyl tube.
- Latex is still the lab benchmark. BRR says "the 80 grams latex tube still has a lower rolling resistance than even the lightest TPU tubes," but latex tubes cannot be made as light, and their airtightness is lower. (Bicycle Rolling Resistance)
What the road says: Rene Herse / Bicycle Quarterly
Drum tests do not include a rider. Rene Herse Cycles, which publishes Bicycle Quarterly, ran roll-down tests on a calm road in Japan, swapping between extralight butyl tubes (Schwalbe SV 14A, 95g) and prototypes of its own TPU tubes (48g) in the same 26 x 2.3in tires. All TPU runs took 31.9 to 32.6 seconds, all butyl runs 33.0 to 33.6 seconds, with "no overlap." (Rene Herse)
Rene Herse translated that to 4.4 watts at 20 km/h, 6.8 W at 30 km/h and 9 W at 40 km/h. It also reports that in earlier tests, TPU and ultra-light latex tubes were "indistinguishable," and that both were significantly faster than butyl tubes and than tubeless setups with a minimum of sealant. (Rene Herse)
Two caveats, both visible in the article: the test used wide 26-inch tires, not a road racing setup, and the prototypes were Rene Herse's own, from a company that sells TPU tubes.
TPU versus tubeless
If rolling resistance is the only question, tubeless is not a clear winner once good tubes are in the picture. BikeRadar says BRR's testing "has shown the difference in efficiency between TPU and latex inner tubes and tubeless is negligible." It notes that BRR's tubeless setup "contained just 20ml of sealant," and that more sealant "marginally increases rolling resistance." (BikeRadar)
What tubeless offers instead is sealing small punctures as you ride, and lower pressures without pinch flats. With tubes, low pressure risks what Frank Berto called a "snake bite." (Berto) Our tire pressure calculator adds 5% when you select tubes for that reason.
The practical catches
Cost. TPU tubes cost more than butyl. We do not quote prices or ratios here because they change often. Check current prices before deciding.
Repairs. BikeRadar says "whether standard puncture repair patches are able to repair TPU inner tubes is also unclear." Vittoria includes a patch with its TPU tubes, and Tubolito and Pirelli sell TPU-specific repair kits. (BikeRadar) If you patch rather than replace, carry the right patches.
Rim brakes. Heat from long rim-brake descents is a concern for thin tubes. Per BikeRadar, "Vittoria says its TPU tubes should only be used in disc brake wheels, Schwalbe and Pirelli both say their TPU tubes can be used in rim brake wheels." (BikeRadar) Check the specific tube before fitting it to a rim-brake bike that sees mountain descents.
Durability. BRR says the 30g Vittoria Ultra Light Speed and 36g ContiTPU "are built more durable" than the 20 to 25g ultralights and "might be a good choice if you need more protection." (Bicycle Rolling Resistance) For a daily road bike, the mid-weight tubes are the sensible middle.
Hookless rims. Tubes can go in hookless rims only inside a hookless-approved tubeless tire, and not if the wheel maker designates the rim tubeless-only, per Schwalbe. (Schwalbe) Details in our hookless tire guide.
Who should bother
- Riders on standard butyl tubes who want free speed: probably yes. The lab data supports roughly 1.4 to 3 W per tire at 80 psi, plus a real weight saving.
- Riders already on light butyl: the rolling gain is small. Buy TPU when your current tubes need replacing, not before.
- Everyone, as a spare: probably yes. BikeRadar notes TPU tubes are "very compact when folded, making them a good option as a spare." (BikeRadar) Tubeless riders still need a spare for the puncture sealant cannot fix.
- Commuters who want cheap and simple: maybe not. BikeRadar's writer keeps "basic butyl inner tubes on my commuter bike because they're cheap, easy." (BikeRadar)
TPU tubes are a modest, real improvement over standard butyl that costs money and a little extra care. A better tube, not a new bike.
What we could not confirm
- Real-road gains on road tires. The roll-down test used 26-inch tires and the tester's own prototypes. We found no independent real-road test on 25 to 32mm road tires.
- Patch compatibility. BikeRadar calls it unclear. We have not tested patches.
- Prices. Deliberately left out.
