Mountain bikes have if anything kept below inflation price-wise. But there is a new top-end that didn’t exist in the past – although unless you are racing competitively, there’s no point venturing there.
My main gripe about the MTB industry is the gradual encroachment of commercialism. We live in a throwaway culture and no more is this apparent than in the world of cycling. I’ve been mountain biking for ten years and still have the same bike, with a service once a year, and new shorts, t-shirts, etc, I probably spend £300 a year max.
