Thanks NM, that’s exactly what I meant, but obviously didn’t explain it very well. No offence taken though RS, hope you enjoyed the hols.
I’m no fan of 650B. Quite the opposite. I’ve always felt that 26 and 29 make sense. They give two usefully different options and if you want a slightly bigger wheel than a standard 26, you can just fit a bigger tyre. But apparently that wasn’t a good idea. So it’s amusing to see that bigger tyres on 650B rims are now the next big thing, especially as some folk clearly didn’t want a wheel as big as a 29er (for whatever reasons).
That said, there probably is a market for B+, but it’s the people who liked the 29er and fancy even more grip and a bit more comfort. Presumably though, the people who wanted a 29er are in a minority and only a fraction of those will want to move to a heavier wheel, so it’s hard to see it taking off.
Unless there are lots of people who really would be better off with a larger wheel but were scared off 29ers for some reason. Maybe you really can sell these people a B+ “all the advantages of a 29er without actually being called a 29er” 🙂
