I have briefly considered doing it, but decided against it. The main benefit of 650b on a steamroller is that it’s possible and looks sick and ‘oh wait you got 650b on steamroller that’s sick bro!’ Which is all good reasons, but that’s it for me. What stops me from doing long distance gravel riding is not the tyre width but the lack of gears, ultimately. Also it’s easier to sell 700c ss/gf wheelset than 650b wheelset. But if you commited to the idea by all means do it, would love to see it here!
