Nothing but 26 inch wheels in my garage and hopefully it will remain so for a very long time. I just can’t see the point of it all, who are all these ordinary punters who DEMAND!!! the highest performance bike no matter what? I like riding bikes for fun, the slower I can go and still have a laugh the better.
But at the end of the day there is so little difference between 26″ and 650b that it hardly matters, when and if my current bikes expire I may get one but not just becuase it is 650b.
As for 29’ers – no way, I really think they will become a bit niche.
