old thread, but for people like me with short reach I would say no. One stems are usually sold in 10mm increments, thus a shorter stem would be then 5mm too short? There are other ways to adjust effective reach on the bike other than the stem, since a shorter stem will effect handling in a more twitchy feel. You can tilt your bars slightly up, you can tilt your shifters slightly up, you can flip stem for a positive rise or buy a stem with a positive rise. You can also buy new bars that have a shorter reach to them. My Cannondale SuperSix EVO had a similar issue of the reach to the shifter was just a touch long. I changed the bars from a 80mm reach to 72mm reach and went down to a narrower bar width 35cm to 33cm and the fit is spot on now.
