Race-Day Weight Savings

Less rotating mass. Faster response.

TPU construction provides a lightweight alternative to a standard butyl inner tube while maintaining the compact size and practical durability BMX riders need for training, racing, and travel.

Ultra-Lightweight

Reduce weight at the wheel

TPU tubes can be significantly lighter than conventional butyl tubes. Reducing rotating mass can help the bike accelerate more quickly and feel more responsive out of the gate.

Efficient Rolling

Built for speed and responsiveness

TPU's smooth, elastic construction is designed to minimize unnecessary friction between the tire and tube, supporting efficient rolling performance for BMX racing.

Compact and Packable

A better race-bag spare

The tube folds into a much smaller package than a typical butyl tube, making it easy to keep a lightweight spare in a gear bag, toolbox, or travel case.

Durable TPU Material

Designed for demanding conditions

TPU offers strong resistance to cuts and pinch-flat damage and remains stable across a broad temperature range. It also provides improved UV resistance compared with latex tubes.

Always match the selected tube size to the tire size printed on the tire sidewall. Use only with compatible rims and tires. TPU tubes require careful installation: remove sharp debris, avoid pinching the tube under the tire bead, lightly inflate before seating the tire, and do not expose an uninstalled tube to high inflation pressure.
