When it came down to offering something as simple as an inner tube, Eclat didn’t want to re-invent what crucially has to be the most compatible part on a bicycle. They got in touch with the best inner tube manufacturer and sourced a tube, which they felt was the perfect blend of quality, construction, and durability. Eclat then widened that tube up to allow it to be compatible with today’s 2.40″ and larger tires. Eclat decided to use their own full-length steel valve which is much stronger and more resilient to damage and the threaded lock ring included allows you to install and inflate the inner tube with way more ease and ensures that the valve is always fully seated and installed correctly. The TUBE AMP inner tube kit is designed to be the perfect extra item to throw in your bag before a session, so Eclat decided to add two in a box, because as any rider knows, you can never have enough spare tubes with you. Material: standard 1.1mm rubber Size: 20" x2.1"-2.5" Schrader valve Lock ring holds the valves securely in place and prevents valve damage Pack of x2 tubes Designed to accommodate for today’s 2.40"+ wider tires Weight: 200g (per tube), 400g pair
