Standard procedure for EVERY new bike is a new fitting, whether by shop or DIY (if you are skilled at it). He needs the new bike, for sure.

Just make sure the saddle height & fore/aft is correct before positioning the bar/stem. It gives him the proper base from the start, and only a degree or two of tilt MAY be required after bar position.

I'm assuming you know the measurements to take for basic fitting...?
