I'm buying my first singlespeed and on various other Forums people seem to throw ridicule at threaded headsets. I've got my shortlist down to the Specialized Langster Steel and the Bianchi Pista Via Brera (which I'll convert to drop bar)... both with threaded steerers / quill stems.
My view on threaded headsets is that:
a) I like them because quill stems are more traditional, retro and beautiful - ie. Cinelli XE
b) I like them because I think they give you more control over geometry - ie. you can effectively lengthen the steerer tube/raise the bars - impossible if you had a cut steerer... unless you flip the stem
So why are people so anti? Is it just youthful ignorance? Maybe I'll find a different - more intelligent - view here.
