Titanium stem comparisons: old vs new
I have two bikes set up with titanium stems/handlebars. My old (650b converted) Kona Explosif has a Moots quill stem with a titec riser bar. The other bike is a Redline D440 29er with a more modern threadless (Moots) stem and a Supergo riser bar.
It seems like the quill stem has a much more compliant ride than the threadless stem does. Has anyone else ridden titanium stems of both varieties ? Can you comment on the ride difference in your experience ?
On a related note --
I've been thinking about a new fork but I'm not sure I can find a threaded chromoly fork with a 410mm-425mm a-c height easily these days.
Hi, riding both varieties too, I cannot tell about any differences in riding characteristics that I would relate to the stem.
Scientifical testing would include riding both stems on one bicycle because the riser bar could partly compensate for the suspension fork et cetera.
Many older moots quill- stems have only one- bolt- clamp for the bar, I have a quill stem with two bolts...
I'd say my experience and impression has been similar though I can't honestly say it is a design vs. contruction difference.

The thread less stem system is stiffer than quill, whether steel or titanium, as far as I can tell. Your ti modern stem is likely to be a bigger diameter and have a more robust clamp too.
i've ridden both varieties as well. the quill stem was a 150mm 1" litespeed tuf nek and the threadless a 1-1/8" 135mm corratec. the tuf nek was extremely flexy. which should be mostly down to its small tube diameters and the length, though. the corratec one is quite bulky. doesn't really flex at all.
The amount of flex in a stem has to be incredibly minimal - maybe a thousandths of a millimeter? Considering tire, rim, suspension (or fork), and bar flex, I'm not sure how you'd be able to feel flex in the stem - unless the bolts were loose.
Each bicycle owned exponentially increases the probability that none is working correctly.
I love this common sense point of view

horizontally, yes. but torsional flex was defenitely noticable. it's the same story with the 3ttt stem on my commuter.

Good luck finding that fork, keep looking on the Bay and here both in the classifieds and in the trade thread.
I agree. I run both and can't tell any difference (though never ran both on the same bike).
