Alienation Feather-Weight BMX TPU 20in Tube

The Alienation Feather-Weight BMX TPU 20in Tube is an ultra-light TPU tube built for BMX racing and street use. TPU construction helps reduce rotating weight while improving puncture and snake bite resistance compared with standard butyl tubes.

This tube fits 20 x 1.75–2.50 tires and uses a premium 40mm Schrader valve. At 67g, it is a lightweight option for BMX riders who want reduced weight, improved resistance, and better air retention than standard butyl tubes.
