does gap between top of steerer tube and top of stem have to be 3mm
Just cut a new steerer tube. The gap between it and the top of the stem is about 1-1.5mm. I know that 3mm seems to be preferred, so the stem cap has something to sink on to. When I crank down the stem cap, I get no rattle or weird feeling in the bars. Is 3mm mandatory or can I be lazy and stick with what I have? As I write, I have this weird feeling I should shut up and go back and finish the job I started by taking off another 1.5-2mm. What a PITA.
