Theres not much you can really say about inner tubes is there? They're black. They hold air. Except when they dont which is when you need a new one.
This IS a new one. Its not handcrafted. Its not made from an exotic, lightweight or expensive material. It wont necessarily make you go faster unless the one you have is broken.
Possibly the most exciting thing about this tube is that comes in a box with the Specialized logos on it and was supplied to you by the cycling nuts at Pedal Heaven
The airstop access line inner tube is made from butyl to ensure effective pressure hold alongside better puncture protection.
