adjustable stem
So I just picked up my Tri bike from the LBS where I had the cables put on. While I could not be happier with the bike, the fit is, of course, way off. I asked when installing the fork that they leave plenty of tube to allow for fitting and this they did. While the current stem on the bike is a 120mm 6 degree rise stem, I would like to put a ritchey adjustable stem on this bike to get the fit better (I already own this adj stem). The LBS said that was fine but said not to plan to use the adj stem long term. Other than the weight and the fact that the stem can, I suppose, wear out and fall during a ride (given how the Ritchey is constructed I got a hard time believing this could happen in my lifetime), what is the downside of the adj stem? I have a hard time believing that I can get the range of possibilities with fixed stems the way I can with the adj stem, thus allowing the best customization of fit.
