Phatman, flipping the stem is no biggie. Just pop the split clamp off the front releasing the handlebars, then removed the top cap, and then the stem..Be careful, your fork may slide out at this point depending on your headset..Then flip the stem,and put it back on. Make sure you tighten the top cap BEFORE you tighten the side bolts.

Good choice on the bike!! Why did you pick the Cro-mo version over the Al version?
