Twitch Ultra Light 20" BMX Inner Tube Description:

Upgrade your ride with the Twitch Ultra Light BMX Inner Tube, engineered from high-performance Thermoplastic Polyurethane (TPU). Designed specifically for racers and riders obsessed with shedding grams, these tubes are up to 70% lighter than standard butyl, significantly reducing rotational mass for snappier acceleration and better handling. Beyond the weight savings, the smooth TPU surface offers lower rolling resistance and superior puncture protection against pinch flats, making it the ultimate performance mod for your wheelset.


Features:

  • Ultra-lightweight construction (60–70% lighter than standard butyl tubes)
  • Reduced rotational weight for improved acceleration
  • Low rolling resistance for maximum speed and efficiency
  • High cut and puncture resistance to prevent flats
  • Compact, packable design—rolls up small enough to fit in a pocket or small bag
  • 24" version available here

Specifications:

  • Diameter: 20" & 24"
  • Valve Type: Presta
  • Valve Length: 48mm
  • Removable Valve Core: Yes
