Vittoria Bike Tubes - Ultra Light Speed TPU Inner Tube - Compatible with Disc Brake Wheels Only (700x25-30c, Presta (FV) 40mm RVC)

• Vittoria Ultra Light Speed bike inner tube is made for pure speed. Designed to offer the lowest rolling resistance possible, Ultra Light Speed are the fastest and lightest tubes ever developed by Vittoria.
• 70% lighter and 14% faster than standard butyl bike tubes. They are made of thermoplastic polyurethane (TPU), which offers lower rolling resistance and are lightweight compared to standard butyl inner tubes.
• By using Ultra Light Speed inner tubes in both tires, you can save up to 160 g. That’s why Ultra Light Speed are the perfect choice for road cyclists that want the highest speed without giving up the practicality and ease of use of a tube tire set-up.
• Compatible with DISC BREAK WHEELS ONLY. Given their lightness, the material they are made of is subject to heat shock. Heat generated by brake pads at the rim level can deteriorate the inner tubes.
