Threadless or threaded headset

right so it's just a matter of taste then? nothing like threadless headsets are cheaper, or you can fit a wider range of different bars, etc?

because if it really is just a matter of taste, I think I'm getting the threaded one - threadless headsets just look too chunky I think

No. Did you even read any of this discussion?

Threadless, 1 1/8th Aheadsets etc are far superior in every aspect.

If you want the quill look though, don't let this stop you buying one.
