Quill stems vs two piece stem(9 posts)

Quill stems vs two piece stemwolfereeno

Any disadvantages to having a quill stem instead of a two piece stem in terms of fit options and bike handling?

My new bike was set up with a quill which seems to go against the current trend these days. The bike's a Kestrel 200sci with a kestrel ems fork.

Consider youself lucky. nmscottfree

There's a long discussion about this on the "general" board.

Basically, the threadless (what you call two piece) is a bit lighter. But both work fine. Use whatever is on the bike, as the cost of switching is far out weighted by the benifiets of either.
Aaaahhh! How can you DO that?!!!Matno

Just kidding. Are there any differences? Not really. A very slight weight penalty accompanies the quill stem, but it's a heck of a lot easier to make height adjustments and at least as easy to make length adjustments (assuming a removable face plate). Of course, by "length adjustments" I mean switching stems...

I highly doubt that there's any performance penalty (I can't speak from experience though). Of course, what brand/model of stem you use might make a difference in flexibility, etc. Does anyone know if there's a difference in stiffness? For example, I just replaced my ancient Sake (I think) stem with a Profile H20, which works fine, but it was too long and now I'm going with a slightly shorter Deda Murex. Any differences there? (I'm sure I'll never notice even if there is).
Less places to squeak on a quillPaulCL

One less "joint" that could cause squeaks.

I have a quill stem. I won't change. First of all, I think the threadless are clunky and ugly. The weight savings is about equivalent to an extra ounce of water in your bottle. I think the threadless stems were bike manufactureres attempt at creating a need, then filing it. IMHO. Paul

You don't get squeaks on a threadless setup b/c everything is clamped tight (that's the way they work). You DO get the squeaks on a quill setup b/c the quill requires clearence inside the steerer and the expanding wend only works at the end. Quill setups are notorious for squeaking due to the short comings inherent in the design. Both systems can have the squealing problem at the handle bar connection since it's all the same.

I just installed my new Deda Murex stem tonight and went for a ride. It was certainly not silent! Not too bad though and may have just needed a good tightening. However, that sucker is noticeably flexy (torsionally). I can rotate the bars a lot just sitting there. Not so noticeable when I'm actually riding, and it was the smoothest ride I've had in a long time (the only difference being the stem). Interesting. The road was the same bumpy crap I always ride, but it felt better. Of course, that could also be due in part to the fact that I finally found the right length of stem. Stem nirvana so to speak. It is a beautiful thing. (And the stem looks cool too). Only problem now is that my stem is black, but the headset is still silver... Oh well. THAT would be a worthless "upgrade".

First - the Deda quality is very questionable and they prove this with each new product. Your squeaking is NOT coming from where you think it is. More likely it's your bars in the stem or your seat post in the frame.

Second - this occured to me after I replied the first time, you still only have ONE connection between the stem and the fork, not two. Think about it.
