The story behind this tube from Éclat: " 
When it came down to offering something as simple as an inner tube, we didn’t want to re-invent what crucially has to be the most compatible part on a bicycle. We got in touch with the best inner tube manufacturer and sourced a tube, which we felt was the perfect blend of quality, construction, and durability. We then widened that tube up to allow it to be compatible with today’s 2.40″ and larger tires.We decided to use our 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 we decided to add two in a box, because as any rider knows, you can never have enough spare tubes with you."
