Revoloop cc Ultra TPU Tubes for Gravel & CX – Featherlight, Fast, and Tough
Upgrade your gravel or cyclocross setup with the lightest, most advanced inner tube in the game. The Revoloop cc Ultra TPU Tube weighs just 30 grams but delivers heavyweight performance across rugged terrain. Designed for speed, reliability, and efficiency, this German-engineered thermoplastic polyurethane (TPU) tube reduces rolling resistance, resists pinch flats, and helps you ride further with less effort. Whether you're racing or adventuring, this tube is the perfect match for modern high-performance tyres.

Because our tubes are made of thermoplastic polyurethane (TPU), they behave differently from traditional butyl tubes. Reduce pressure by 0.1–0.3 bar for optimal ride quality—especially on MTB setups.
The max pressure is determined by your tyre—not the tube. Always follow the tyre’s printed maximum rating.
You can slightly inflate it for positioning, but never go above 0.5 bar—or 0.2 bar for fat tubes—unless it's inside the tyre casing.
Yes! All our valve cores are threaded and removable. You can tighten or replace them if needed.
We recommend using disc brakes. TPU isn't as heat-resistant as butyl, so prolonged braking with rim brakes may compromise the tube.
Yes, sealant won’t damage the TPU—but it won’t reliably seal punctures. Use it only as a short-term measure.
Yes, CO₂ cartridges work perfectly with Revoloop TPU tubes.
Yes! Use our TPU-specific patch kit. Clean the area, apply the patch, let it set, and reinflate. Butyl repair kits will not work.
Our tubes fit tyres from 23 mm (road) up to 125 mm (fat bikes). Plus-size (2.6”–3”) compatibility is in development.
We offer 40 mm, 60 mm, and 80 mm valves. A 100 mm version is on the way.
No. TPU tubes retain a stretched shape. You can reuse them in the same or larger tyre—but not in a smaller one.
No powder needed. TPU installs cleanly and smoothly without it.
Yes, our injection-moulded TPU valves are internally threaded and work with standard valve extensions.
We use 100% German-sourced TPU—offering a perfect balance of durability, elasticity, and lightness.
Our co-extruded tubes combine up to 7 layers of TPU—balancing low rolling resistance with high puncture protection—all in walls just 150–300 µm thick.
This is normal and purely cosmetic. The brown tint comes from rubber particles diffusing from the tyre—not a sign of wear or damage.
Yes! TPU is recyclable. Our tubes are lightweight for lower emissions, and we’re developing a platform for product take-back and reuse.
We recycle all production waste, use recycled packaging, and constantly improve our sustainability practices.
