Quill stem adaptor: YAY/NAY?

Thinking about getting a quill stem adaptor, dont know too much about them...
Any major pros/cons i should be aware of? cheers

NAY, as far as I can see they combine the worst aspects of both systems and are heavier than ether.

I'm sure there are times when they are useful . Maybe tell us more about why you might need one and it might be easier to answer your question.

basically, i have really quite short arms.
i have looked around for a decent quill stem under 60mm reach with some kind of system that allows bar changes without the removal of bar tape (like the cinelli oyster stem in this thread: http://www.lfgss.com/thread91406.html )
from what ive seen from other non quill stems, theres alot more choice in length of reach and obviously various bolted clamp systems do allow removal of bars without removing bar tape.
this would be my reasoning for wanting a quill stem adaptor...

Well if you envisage swapping your bars quite often than I see your point!

Adaptors work fine, most people who prefer a-head do so because it is simpler, lighter and stiffer than quill. most people who prefer quill do so because it is more elegant and vertically adjustable than an a-head.

If you dont mind missing out on these advantages of the two systems than you have nothing to fear. One other thing is that you might like to consider is how a shorter stem will affect the handling of your bike. Shorter stems give quicker twitchier handling, longer stems give slower more stable handling.

IME the difference in handling between a short (e.g. 70mm like I ride now) and 110mm (how I used to ride) isn't noticeable. Also if you're swapping bars around, then the width and dimensions of the bars will make at least as much difference to the handling as the length of the stem itself.

think im gonna have to sacrifice easier handling for not being in crippling back pain hahah. cheers for the help its appreciated

I used an adaptor for a while......easier to experiment with stem lengths this way (not having to re-tape bars etc). In the end, when I had my frame re-sprayed, I had the fork column changed to allow the fitting of an aheadset...

You could get multiple stems and swap them over with the bars as a whole. Hassle, but easier than removing tape. Or find a setup that suits you and stick with it.

Yay, although it looks terrible.
Wasn't it tester, who stated here, that it was a lot stiffer than a normal quill stem?

but that's not saying much.

if you need a stem that is less than 60mm your bike doesnt fit. Or you think you need one but dont actually - most likely case.
