Temporary lockup of Campy Record Ergo Shifter

Hello All:

Today I had an odd thing happen with my rear Record Ergo shifter: it
would not down shift (go to larger cogs). The lever simply would not
move. I ended up getting it to shift by pulling on the exposed cable
along the downtube with my left hand and shifting with my right. This
was quite a task and I sort-of had to hit the up shift lever first and
then push the lever for the down shift. The two levers seemed to somehow
be interacting. My efforts probably provided entertainment for other
riders.

Later in the ride it worked fine.

Now I would like to take steps to correct this issue. The group is from
the fall of 2000 so I suppose it could be either a 2000 or 2001 model.
Not sure and not sure how to tell. It is 9sp. I have done no maintenance
whatsoever to the shifters in the 7 years I have the bike and it has
always performed perfectly until today.

Anyone want to suggest a few steps to help me figure this thing out?
Lube it? Rebuild it? Send it to Vecchio's?

Rinse with copious quantities of a penetrating lubricant.
Not WD40.

with ergo, if the thumb lever isn't fully "home", it can lock the
other lever. i'd recommend lubing the pivot of the thumb button. i
have similar problems with my left shifter, because i gunk up the
inside of that pivot at least once a year. fold the hood up over
the button, hit it with some wd-40 to degunk it, work it well and
then oil it and work it again.

just a guess though.

But not WD40 because that will gunk it up quickly.

Look for a simple problem with the thumb lever return - corrosion is
likely on the thumb lever pivot/return spring. Try a drop of oil and
work the lever a few times. Thumb lever bent? Lever cover jammed in the
slot? Usually a small external issue.

Thanks! I have looked and can't find any obvious problem and now and
cannot get it to lock up again. Have applied lube to all the moving
parts so we'll hope it works till the off season when I can send it off
to Vecchio's.

Cheers,

That's true, it could be a frayed gear wire but the frayed bits sticking
in one's hand are an early warning!

Undoubtedly it locked up because the thumb button didn't come all the

way up. Could be hood/bar tape fouling it, thumb button return spring
weak/broken, teeny spring in thumb button return not working due to
corrosion..After all that time, a rebuild would probably be a good
idea. Send it to me for a 1 day turnaround.

Thanks! How about if I try to nurse it along till the end of the riding
season here in Salt Lake City. Look for it around Thanksgiving.

Cheers,

Might try to both trim the hood around the thumb button, make the
'slot' larger, ensure the bar tape isn't around the shift guts and
spray a little lube on the hinge of the thumb button.

A good point....ow!
Where's all this red stuff on the bar tape coming from?

Thanks! Checked for clearance and lubed yesterday and have been unable
to get the lockup to repeat.
