Although the threadless fork's stem choices are less elegant in appearance than the classic Cinelli 1A and cutting to fit the correct stack height is a one-shot-deal they make sense for me.
The 1 1/8" standard mated to a quality stem & bars makes for a really solid feeling front end on my Soma Stanyan.
Dealing with injury recovery I've changed stems three times to dial fit in, a simple ten minute job w/ threadless, not so much w/ a classic set-up.
