The worst part of old shifters is that you have to use old (design)
freewheels.


Really? why is that?

Friction and classic equipment works well, in fact better, with modern
tooth design freewheels and cassettes. Up to eightish though; friction
9-10-11 is dicey. Seven systems are fantastically better with modern
freewheels/cassettes than with classic tooth forms.

I have no problems shifting with bar-ends in friction mode, an 11-32
9-speed cassette, and a Shimano Tiagra derailer.

I have done a lot of "upgrades" and usually wind up saving only the
frame/fork in the end, The only reason I bother is that they don't make
such large (68cm) frames any more.

mmmm.... I dunno.

A while back I realized that due to the nature of riding that I did, I
wanted to try a Real Touring Bike(tm) and that also I wanted something
with a dynohub and real lighting. I bought a Trek 620 off Craigslist
and rehabbed it with new wheels, drivetrain, etc. and it ended up
probably costing me about the same as buying a new off the rack 520
without any of the stuff I really wanted. Only real "downside" for
someone who would prefer modern stuff is the DT shifters instead of
brifters, but that was a conscious decision that I made (and the indexed
Shimano DT shifters were some of the more expensive parts that I bought
for it.)

You apparently have more sensitive fingers than many whiny
riders then. Frequent complaint is too slight a lever motion
for one gear shift.

Frankly, I do not care that mathematically there are an infinite number of
possible coordinates within a triangle, when the goal is to optimize a
component. Anyone who did real world engineering would know better than
to waste time on abstractions.

Use of abstractions is hardly a waste of time. Perhaps
you mean to say the opposite of what you said? You
seem to be implying that the OP was adding complexity
that served no purpose. (Not that I do think so)
This would be the opposite of abstraction.

Joggers are evil.

Slightly less so than inline skaters.

Sorry, I meant old (first generation) indexed shifters.

I've got a firend who rides a bike with a 10 speed rear, shifted by
suntour friction stem shifters. He says it works just fine.


I'm sure it does, if you have the touch.
