TPU (thermoplastic polyurethane) inner tubes weigh 30-50g versus a standard butyl tube’s 90-120g, pack to the size of a golf ball, and claim rolling resistance comparable to tubeless setups without the sealant mess and tubeless-specific tyre complexity. In 2026, they have gone from a curiosity to a genuine alternative worth serious evaluation. Here is what the data actually says.

Tubolito S-Tubo Road 700c
The Tubolito S-Tubo weighs just 30g and packs to approximately the size of a golf ball, making it the lightest road tube available and an obvious choice for any rider who carries a spare tube in a jersey pocket — the weight and volume savings over a standard butyl spare are substantial. Independent testing by Bicycle Rolling Resistance places the S-Tubo within 2 watts of a comparable tubeless setup at 45psi, meaning the rolling resistance argument against TPU tubes is largely resolved at this product’s level of manufacturing quality.
- Lightweight – More than 70% lighter than traditional butyl tubes.
- Smooth Ride – Less rolling resistance equals less fatique
- Strong -TPU is 50% stronger than traditional butyl rubber means less punctures on your rides.
REVOLOOP Race TPU Inner Tube
REVOLOOP’s Race tube is made from a higher-grade TPU compound than most competitors, producing lower measured air permeation — in practical terms, you will lose approximately 5psi overnight rather than the 10-15psi typical of butyl tubes, which means your tyre pressure is closer to your set point at the start of a ride without morning pump rituals. At $29, it is the best performance-per-dollar TPU tube currently available, and its orange colouring makes it dramatically easier to locate punctures compared to transparent competitors.

reTyre Core TPU
The reTyre Core is a Norwegian-made TPU tube priced to compete with mid-range butyl tubes rather than the premium segment — at $22, it brings the core TPU benefits (light weight, compact pack, low rolling resistance) to budget-conscious riders without the $35-40 premium of Tubolito or Pirelli. The valve is available in 40mm and 60mm Presta lengths, covering both shallow and deep section rims.

Pirelli Smartube
Pirelli entered the TPU tube market with the Smartube, using their tyre manufacturing expertise to produce a tube with a proprietary TPU compound claimed to have 30% better puncture resistance than the Tubolito equivalent — a meaningful advantage for riders who frequently encounter glass or debris on training rides where durability matters more than every gram of weight savings. The Smartube is also available in a wider range of valve lengths and widths to cover cyclocross, gravel, and mountain bike applications.

Tubolito S-Tubo Road 700c
For road cyclists who carry a spare tube, switching to the S-Tubo is one of the easiest weight savings available — 60g saved per spare tube, packed to golf-ball size, with rolling resistance within 2 watts of tubeless. A straightforward upgrade with no meaningful downsides.

TPU tubes are not a replacement for tubeless in all conditions: if you ride terrain where sealant-preventable punctures (thorns, small glass) are common, tubeless still wins. TPU tubes excel for smooth road riding where pinch flats and rim damage are more likely than thorn punctures.
Valve length must match your rim depth: 40mm valves work for rims under 40mm deep; use 60mm for 50-60mm aero rims; 80mm for the deepest clincher rims.
Patch compatibility is improving but not universal — TPU tubes require TPU-specific patches that must be carried alongside the tube; standard rubber cement patches do not bond reliably with thermoplastic materials.
The primary argument for TPU over tubeless is simplicity on training rides: no sealant to refresh, no tubeless tyre mounting labour, and a spare tube that fits in a jersey pocket. Tubeless still wins for race-day where sealing small punctures automatically is worth the setup complexity.
Final Thoughts
TPU tubes are not going to replace tubeless for serious racing or rough terrain riding, but they occupy a genuinely useful niche for road and gravel training rides where simplicity and emergency repair convenience matter more than maximum puncture protection. Start with REVOLOOP Race for value; upgrade to Tubolito for the lightest possible spare.
