Another little old lady comment from Krygowski. To shift
downtube
shifters you have to pause pedalling.

 
Oh fer fucks sake....yeah, that's great advice....'pause
pedaling while shifting'....wow, what a fucking moron.
 

This causes the man behind you with
brifters to run into the back of you as you suddenly slow
down.

 
Not if they're paying attention, and it wouldn't have been
any different if the guy behind had downtube shifters.
 

They did
have 10 speed downtube shifters. Since they were lighter
than brifters
why did not some pro's with the emphasis on lighter and
lighter weight use them?

 
I don't recall any manufacturer marketing 10sp index down
tube shifters. I'll concede I may just never have noticed,
but the question about they the pro's would never use them
is a really stupid strawman argument.
 
First off, dipshit, You don't have to change cadence/power
any more/less with down tube shifters than with integrated
shifters.
 
Second, It's the dynamic of being forced to sit that affects
cadence and power. With downtube shifters you pretty much
are forced to sit to shift. The reason pros don't use
downtube shifters is that the ability to respond quickly and
shift while out of the saddle trumps the weight savings.
FWIW - some people who compete in hill climb events (e.g.
https://bumpshillclimb.com/) do often still use downtube
shifters for the weight savings. Many riders also use a
single chain ring and a single brake (UCI rules don't apply
to those races).
 

Day after day you have not added one thing to the group
except stupid
statement after stupid statement.

 
oh, you mean like " To shift downtube shifters you have to
pause pedalling." ? Oh, wait, that was you.
 

Jobst's bike was 66 cm and made from 1" rather low grade
steel compared
to what is available today.

 
You have no fucking clue what Jobst rode. A rider of his
caliber was most likely riding at least something along the
lines of Columbus SL, which in the hands of a competent
builder is a stiff as any steel frame made today. There have
been numerous discussions in this forum about blind tests of
steel bikes built with different grades of tubing where the
winner was more often than not the lower grade tubing.
 

It was unbelievably flexy and with old
downtube shifters and I think it a miracle that he could
keep it upright
when going around turns it would start flexing the frame
and wheels (36
spoke) and he would have to counter steer it to keep it
going in the
direction he wanted it to go.

 
Unless you rode it - which we know you never did - you have
no fucking clue how flexy it was or what it took to control
it. FFS kunich, Day after day you have not added one thing
to the group except stupid statement after stupid statement.
 
Tell us again how your shifting improved after you got
special campagnolo non-stretch shifter cables?
 

But you have never had experiences like that. Not that
that is a negative
- riding within your pesonal and bike selection's
capabilities - but why
do you pretend to give advice on these subjects?

 
oh, you mean like " To shift downtube shifters you have to
pause pedalling." ? Oh, wait, that was you.
 
 
 

 
Campagnolo and Shimano offered bar end Ten shifters which
can be mounted on DT shift bosses. We've installed a handful
of each (vs hundreds of Ergo/STi). An outlier format but not
zero.

Flunky tells us that he had a modern racing bike but now he claims to
have downtube shifters. Since I raced with downtube shifters and was
faster than the other Cat 4's and 5's and I had to pause slightly to
reach down to shift because among other things looking down is not
looking where you're going, I really have to wonder what he is on
about. On most bikes the downtube shifters are in the arc of your
pedaling knees so how in the hell can you NOT pause even if you didn't
care where you're going. And reaching down and fumbling around trying
to find the correct lever is worse than looking down.

Why would you look at your shifters?  They're always in the same place.
Do you look down when you grab your water bottle?

I don't know about most bikes, but I have never experienced downtube
shifters within the circle described by the knees.  I reach down with my
right hand, locate the shifters by touch, and shift either one.  I do
have to reduce the force applied, but always keep pedaling.  Works
great.
