Early tubeless systems also seemed destined to stay niche. They were aimed at XC racers and weight-weenies. But of course, the technology surrounding them caught up. Tires improved, latex-based sealant arrived, and most recently, the tire plug made the leap from cars to bikes. Suddenly, it was hard to imagine the days of the inner tube.
Tubeless plugs all do essentially the same thing, but each uses a different method. Blackburn and Genuine Innovations simply scaled down the plug system we all should (but probably don’t) have in our glove box. And Dynaplug scaled down a unique system of its own.
Instead of waiting until I got enough pinch flats to exhaust the supply of the 53 various plugs I planned to go through, I sat down in the garage with four tires, two bottles of Stan’s, an air compressor, an X-Acto knife, goggles and a lab coat in an effort to find which plug I want with me when the sun is going down fast, and my tire pressure is going down faster.
The first mobile phones showed little promise of ever appealing to the masses. But then, cellular networks expanded, microprocessors arrived and suddenly it was hard to imagine the days of the land line.
