Eclipse said the tube has been under development for seven years and can be repaired with a repair patch. Depending on size, the tube weighs around 50g, compared with over 100g for a premium lightweight tube from competing manufacturers.

The cost, however, is euro 65 each. not a price many cyclists will be keen to spend to save 50g or so.
