Featuring a high-quality thermoplastic elastomer (TPU) material, this inner tube is 64% lighter and has a 50% smaller packed size when compared to traditional standard tubes. Made for tyres from 30mm to 47mm width, this model is engineered for the demands of modern cyclocross and gravel riding disciplines. Compatible with 700c tyres and ready for 650B wheels, it offers the same amount of comfort as a butyl tube but with double the toughness. Suitable for disc brakes and rim brakes, this is a perfect all-rounder for tackling mixed terrains, wherever your next adventure takes you. The Ultralight, Extra Durable Bicycle Tube For a long time, the innertube has been overlooked in the bicycle industry. Tubolito are changing that. Their vision: The perfect inner tube, developed for the optimal cycling experience. Lightweight: 2/3 Lighter Than A Standard Tube Every gram counts. Even more if you reduce the rotational weight. Tubolito offers an easy and achievable weight tuning. Tubolito can provide this solution by combining a new material with a self-developed production technology.  Tough 2x Stronger Than Standard Tubes Lighter and more robust. Tubolito solves this contradiction by using a new concept: manufacturing the tube with a thermoplastic elastomer, called TPU - materials known for durability and excellent damping. Their goal to transform these excellent material characteristics into an outstanding bicycle product, reducing contact areas and seams. Developed and Manufactured in Europe  Tubolito tubes are manufactured in Europe, and all assembly parts are sourced in Europe. This allows Tubolito to maintain very high-quality standards.  Manufacturer's Part Numbers: TL-33000053 Orange Presta 60mm 700c x 30-47mm TL-33000052 Orange Presta 42mm 700c x 30-47mm
