I'm going to try a shorter stem on one of my bikes. Now I've done this before, and often stems have the correct torque printed on 'em at each end. I just do them up until I'm satisfied- basically somewhere between "it isn't loose" and "I'm going red in the face". But closer to "it isn't loose". Only not that close. Must be a better way; hence this post. Might well be relevant: no carbon bits involved here.
