Generally there's about a 2cm difference, so based upon this information alone he should be looking
at a 60cm frame. However, of greater importance is top tube length and seat tube angle. If he likes
the fit of his current bike he should concentrate on getting the reach (distance from saddle to
bars) and KOPS (knee over pedal spindle) measurements correct. There's lots of adjustment in
effective seat tube length (saddle to bottom bracket) available in almost any bike you can think of.
