You'll note, alfeng, your knowledge of Newtonian mechanics was lacking.
Your rant proves nothing. Show me evidence that Camapgnolo shifters shift better than Shimano. Evidence.
Well, Troll ...
It appears that this is yet another example of the lack "reason, critical thought, and listening" on YOUR part!
BECAUSE, if you could
listen, then you would be able to understand the example of "dwell" satisfies your request for "verifiable evidence" and that "dwell" is a phenomenon which has been repeated so often (
umm, like the effects of Gravity) that it has a commonly accepted name.
Your apparent lack of acceptance that the phenomenon exists as a part of the Shimano experience for the past two decades simply re-enforces my previous observation that your experience with a Shimano equipped bike was limited to the equivalent of
parking-lot-test-ride.
Regardless of how much-or-little understanding 'I' might have of any of the Laws of Physics, I apparently have more working knowledge than you because you have not been able to apply the
reasoning &
critical thought necessary to understand WHY the eccentric take up spool which Shimano's mechanical Road shifters have will forever present a problem until the head engineer who must have been on the team which brought the World the BioPace chainrings is superseded by someone who is not wedded to the concept OR perhaps he-or-some-subordinate will have an epiphany and change the "timing" of the cam.
- I think that YOU need to be worried about how little dhk2 apparently knows-or-remembers about Physics because he claims to have a degree in Engineering & apparently (by his own, earlier declaration) works for a company which does some sub-contracting work for NASA even though he claims to never have seen 'p' used to describe "Momentum" ...

- Hey, after more than 40 years, I only failed to remember that it was a lower case 'p' instead of an upper case 'P' when used in its most basic formula to describe "Momentum" ... we already know that dhk2's memory is either faulty or he never learned what he as supposed to with regard to "Newtonian mechanics" (I guess that 'C' & 'D' are satisfactory, passing grades in some programs) ... let's check YOUR memory in 40+ years ...
In other words, the eccentric spool design IS the evidence.
- but, you would apparently need to use some critical thinking to be able to discern that
- and/or, to subsequently be able to reason why "dwell" occurs as a consequence
In other words, the phenomenon IS the evidence.
- but, you would apparently need to be capable of using some critical thinking to discern that
- and/or, you would need to be a able to reason if-this-than-that
- FYI. No one truly understands how Gravity works, yet.
BTW. Do YOU understand the difference between good, better, best as qualifiers?
OR, small, smaller, smallest?
OR, big, bigger, biggest?
Et cetera ...
FOR YOUR INFORMATION ...
- if A is bigger than B, then B is smaller than A
- if D is worse than C, then C is better than D
- et cetera
Shimano shifters are good, but they are handicapped by "dwell."
SRAM shifters can be considered to be better than Shimano shifters because they are not handicapped by "dwell" HOWEVER pre-Yaw SRAM front derailleurs are handicapped because SRAM's front shifter is not capable of
trimming the front derailluer's cage.
Because Campagnolo shifters are not handicapped by "dwell" AND the front derailleur can be
trimmed with Campagnolo shifters it can therefore be suggested that Campagnolo shifters are BETTER than
both Shimano & SRAM shifters (
both limitations could be easily remedied & thereby make Shimano & SRAM shifters equal to Campagnolo shifters; but, until THAT day arrives, Campagnolo shifters will remain as being better).
Q.E.D.
What you have demonstrated is THAT understanding "dwell" might require more "critical thinking" on your part than you can fathom.
BTW2. As I stated before, ANY observation by ANY individual is considered to be an
Empirical Observation ...
You are truly in a delusional world if you believe that how you arbitrarily re-define terms & concepts is the reality understood by the rest of the World.
Perhaps you should stick with cutting-and-pasting rather than an exhibition of your inferior knowledge, lack of reasoning, lack of critical thought & lack of ability to comprehend the various posts & replies to which you feel compelled to comment on BECAUSE the only knowledge which you have repeatedly demonstrated knowing on a consistent basis is how to look up information via the index in the back of the text books which you own + to parrot information which you have read which may-or-may-not be correct + post pictures of bikes for which (
for all we know!?!) you could be a paid shill + to troll with your hollow "show me numbers" mantra despite your apparent inability to fathom the numerical summations when they are presented to you.
