I didn't think there was either but a post somewhere on here talks about an injury caused by one. I presume that they are cut short then for aesthetic reasons. The problem occurs if they are either cut too short, too soon (as in the OP's case??) or if the bike is used by another rider, for example if it were to be sold on. By the way, I don't have a problem with ahead stems myself (3 bikes in the family with them) but am concerned about this issue of fit. I am also pretty sure that a new upright stem or raiser will solve most fit problems but not everyone is aware of that (although the company that makes the raiser is probably doing a roaring trade.) I think that it is also true to say that the quill stem also sometimes needed the same treatment, i.e. replacing or raising (not just adjusting).
I am a bit concerned however that the bike shop let the OP go off with the new bike without making sure that he was happy with the fit. I would also appreciate it if a bike shop person could just come on here and explain exactly when the steerer tube is cut and how they decide by how much.
I would really like to know this.
