Bike Works in Edinburgh can get through 100 inner tubes in a week. Multiply this up across Scotland and that’s thousands and thousands.

And that’s thousands and thousands of useless plastic dust caps, no one needs them, no one wants them, the top mechanics at Bike Works chuck them in recycling, and no one on the chain gang bothers with the extra micro grams.

So, Specialized, Nutrak, Continental, Michelin, Schwalbe, apply David Brailsford’s marginal gains to climate change and rid the world of this superfluous, irritating, plastic irrelevance.

Next up, the useless wee valve lock-nut, the cardboard box and making life-long friends with your inner tubes.
