PSIKIC GRAVEL TPU Innertubes 700c Presta Valve

Upgrade from bulky butyl without sacrificing the durability gravel riding demands.

The PS!KiC Gravel TPU Inner Tube is an updated, reinforced version of the brand’s road tube, engineered with thicker TPU material for wider tires and rougher terrain. It delivers the compact size and low weight TPU tubes are known for, with added durability for gravel, all-road and adventure riding.

Designed for 700C tires up to 52mm wide, each tube folds down remarkably small—making it easy to carry in a saddle bag, frame bag or jersey pocket. It is an ideal everyday tube or space-saving emergency backup for tubed and tubeless setups.

Independent Recognition

Road.cc awarded the narrower PS!KiC road version an 8/10 rating, highlighting its low weight, compact packed size, easy-fitting matte surface and strong performance during winter testing on wet, broken roads. This updated gravel edition builds on that design with thicker material and compatibility with substantially wider tires.

Installation Notes

1. Add only enough air for the tube to begin taking shape before installation.

2. Ensure the tube is completely inside the tire and is not trapped beneath the tire bead.

3. Never fully inflate a TPU tube outside a mounted tire.

4. Use only a TPU-compatible patch kit for repairs.

5. Check tire pressure before every ride. TPU tubes may require more frequent pressure top-ups than butyl tubes.

Important: The 45mm valve is intended primarily for standard and shallow-section rims. Confirm that sufficient valve length will remain exposed when using deeper rims.

Compact enough to carry anywhere. Built for the road less traveled.
