• I'm confused :s

    I meant would it be possible / advisable to run a 32mm X 650b tyre on the 650b Crest rims? Or would you need to run something bigger to be on the safe side?

  • The Crest rims have the same width on both 650b and 700c.

    I ran 28mm which is the smallest you can go on that width which can also be said the same if there's a 650b 28mm tyres.

    Nice thing about the width, it fit all tyres sizes, although I struggle to notice any difference between 17mm and 21mm with when riding with the 42mm Hetres.
