Campy 10 rear shift problems



I have recently had a problem with upshifting (smaller cogs), where
the shifter will jump 2 or 3 cogs instead of one on a button push.
Being very careful with upshifting (good hard push, then release)
seems to help control it. Downshifting is fine.

The shifter feels like its skipping over the index points, like if
you're tentative with the push and hold the button mid-way; sort of
like a ratchet skipping over worn teeth. It seems to happen mostly in
the middle/lower part of the cassette.. but that may just be where I
mostly run.

Shifters are Mirage 10, about a year old with maybe 5000k's, on a
Shimergo setup (shimano 9 cassette with hubbub cable routing)

Anyone have an idea what's going on?

Worn or broken G-springs.
Cheap, regular maintenance issue; not a crisis.

These shifters are Mirage QS 10 sp (2007) with the escape mechanism..
do they still have G springs?

Bump... no-one ever looked inside one of these beasties?

Poking around this morning with the rubber hood off, I suspect that
the tooth on the thumb shifter may have worn down.. but won't be able
to confirm unless I pull the shifter apart.

On the Campy PDf http://shrinkify.com/1j8 from Centaur on down there
are no G-springs. To answer your question I think something might be
ary with you Shimero setup. I have a feeling that the amount of cable
pull is out of whack.

nope... cable pull is not the problem. This is a setup that's been
working fine for nearly a year. The thumb shifter drops down a
matching number of multiple index positions for the cogs.

I think I'll have to get into it and poke around.. which is a problem,
as this is my commuter.. and N=1 at the moment.

Bump the thread. He hopes someone responds before the thread falls too

Someone who knows should explain to him the difference between
usenet and www forums.

Because heaven forbid somebody internets wrong.

Crimony, there's one in every crowd...the internet etiquette know-it-
all, correcting everybody else. Seriously..every newsgroup, forum,
listserv, you have the posting police.

But without Michael Press's post, how would Duncan McCrae know his

How is it different.. do you go and search through old threads for
questions you might like to answer?

Don't like it? kill-file me.

Hank said the method is to refresh a thread.
I spoke to that.

How about you wait for me to tell you what I like and dislike?
I do not use kill files. Waste of time.

Yet all the time you spend telling people that they're internetting
incorrectly is NOT a waste of time?

You do not characterize my intent or means correctly.
I asked someone who understands www forums to explain
the difference to duncan. Why would you not explain it
to him? Does `bump' server a purpose in usenet groups?

FFS..

if you are so concerned about this violation of etiquette, why don't
_you_ explain to to me?

Sure...It repeats the question in a new message in case someone with
an answer didn't see it the first time around, or didn't have time to
reply. If they're using Google Groups, as many here do, or certain
newsreaders, it will push the thread to the top with its recent
activity. Obviously, this doesn't apply to how you read the group, but
if that's the case, why do you bother replying? I mean you're
obviously annoyed that your time's been wasted, so why not cut your
losses and skip over the post?

You misunderstand my concern. I do not explain it because
I do not know enough of web based forums to do so. That is
why I asked for someone who does.

Not so obvious. And I am not annoyed. I have said some things
about what I am doing, and you ignore them; instead you make
up things such as a concern for losses. Apparently you think
I am engaged in a debate and have sustained losses. Losses to you?
