Pirelli Scorpion SmarTUBE TPU Inner Tube (29in & 27.5in versions)

The Pirelli Scorpion SmarTUBE is a lightweight TPU (thermoplastic polyurethane) inner tube for mountain bikes. It packs smaller and weighs far less than a standard butyl tube, and is aimed at trail, marathon and enduro riders who want fewer punctures.
