if I have 700 x 35c rims/tyres currently, what size 650b tyres would I have to run to retain the same bb drop?
700x23 is about the same as 650bx42 iirc so I assume around 650bx54 tyresfor 700x35, tho a lil BB drop is probs okay, depending where it's at in the first place.
You can drop even further if you use clip less pedals, BB height currently work with clip and strap.
