Thanks diesel-dad, that gives me something to work with. By riding the bike around, and putting my hands on "imaginary" hoods and tops. 30-40mm shorter is about the range that feels right. That means I'm looking for a 70 or 80mm stem.
At what point is a stem too short? ie, at what stage to you say the frame is just too big, sell it and buy something smaller?
