We probably talk about bikes way too much in the Dirt office. Sometimes it’s about a new product that’s just turned up, other times it’s about a rider or a photo, and then occasionally we get all nostalgic and start rabbiting on about various random things from the past. I think it was one of those occasions that led us to discuss what products or innovations we thought had changed mountain biking and helped turn it into the sport that it is today. We could think of loads of great products over the years, but had they changed our sport? The answer was no for most of them, but in the end we came up with this list of 15 which we think really have had a strong influence on our sport. Can you think of any we’ve missed? Anyway, click on the bits below to see our selection in no particular order…
