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.
Cut rotational weight where it matters most. The Tier 1 Twitch TPU Inner Tube is a lightweight BMX racing upgrade built for faster acceleration, efficient rolling, and a dramatically smaller packed size than a traditional butyl tube. It is an ideal race-day tube and an easy-to-carry spare for riders who want performance without unnecessary weight.

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