Quoted message said:1. Make something easy to adjust and it will be adjusted properly, make it diffcult to adjust and
it will only be crudely adjusted.
True, but you can't really call threadless "difficult to adjust."
Quoted message said:2. Each adjustment should be independent of other adjustments.
Yes, nice.
Quoted message said:In my view the fact that the headset needs to be adjusted each time the handlebar height is
changed makes about as much sense and requiring the BB to be adjusted each time the seat height is
adjusted.
I does seem conceptually unfavorable. Practically speaking, it isn't too big of a deal.
Quoted message said:It is only the fact that the handlebar height is less critical than the seat height that lets this
compromise exit.
True, it isn't very critical, which is right next to saying it isn't really a compromise.
Quoted message said:I dislike the fact that to adjust the handle bar height you have to adjust the headset. Sure they
are easier to adjust but with a quill stem you don't need to adjust it.
Conceptually, yes. Practically, not too big of a deal.
Quoted message said:Out on a ride, want to raise the handle bars a bit to experiment, with a quill stem it is a 30
second deal.
Sure, but I never seem to need to adjust height while on a ride. I test my setups on the trainer.
If out-on-a-ride adjustment is really important to you, then the marginal edge would go to
threaded. It is not important to me. I would think that someone with your experience would know how
high you want the bars.
This is kind of like the "friction option" of bar-end shifters in case one falls down and the crash
impact bends the r-der and/or hanger, and the result is bolloxed indexing. I've always had the
friction option. In tens of thousands of miles, I've never needed this option. It is a good idea
that I suspect isn't at all important in practice. Most crashes that mess the r-der or hanger will
probably result in bike ride termination, and not because of the hanger or r-der damage.
Quoted message said:I have also seen much longer quill stems available than threadless. I bought a quill stem with
about 10 inches of rise, stainless steel shaft with an aluminum clamp etc. Not too heavy and
amazingly stiff.
This sounds like a need created by a bigger problem of improperly sized frames. "Availability" is
perhaps important, but it alone doesn't separate the two systems (technically) for the purposes of
most riders. I wouldn't buy a frame that required odd-ball stems in the first place. "Odd-ball" has
its own availability problems when simply standing alone. With regard to "availability," removable
clamps seem to be more ubiquitous on threadless stems than threaded. This is for no apparent
technical reason, anymore than a threadless couldn't be built with a lot of rise. Personally, I
really like the idea of removable clamps because I feel reach is about as important as height.
I have a threadless bike and some threaded bikes. The threadless bike works just fine. If someone
thinks they need a lot of flexibility and adjustability, then perhaps threaded has the edge. I
haven't needed that level of adjustment. I think threaded is aesthetically more pleasing.
