Have got enough bits to build up my new (secondhand) Bfe frame, I find out I have made school boy error!! The steering tube only comes out of the top of my headset by 20mm, is this enough?
Even without spacers it will only be half way up the stem that I have. Can I leave a gap? What is the problem? Can I get a narrower stem?
Any experience and or advice would be good. Already kicking myself so no more of that is needed.
