Size difference.

Anyone know what is the inch difference between 700c and 650c ? I was wondering if it is possible to fit a 700c wheel on a frame that uses 650c wheels.

Did you take geometry in high school? C'mon, stretch yourself.

About 2". Without any geometry, only Google.

unlikely

622 mm (700c) - 571 mm (650c) = 51 mm = 2.00"

It's unlikely that a 700c wheel will fit in a 650c frame/fork.

edit: And even if the wheel did fit, it would probably throw off the bottom bracket height, steering geometry, etc.

those measurements are closer to the diameter without an
inflated tire mounted on the rim.
...but yeah, a 700c wheel will definately not fit in a
650c fork and in all cases i can think of also not in a 650c rear.
