Then it hit me that my stem length is too long. I've talked to a couple of LBS guys and they agree. Call me cheap but the labor prices for making a change seem high. So my question is how hard is it to change yourself? My bike is a farily old (15 yrs) Diamonback. I have the old style threaded quill. I'd like to put on an adaptor and install a threadless stem. How do you know what length you need without investing in a time consuming and expensive fitting at the LBS. I currently have a 90mm stem, I think a 65mm is about right.
Help!!!!!!!!!!!!!!!!
