Ergo-shifter jamming/maintenance(11 posts)

Ergo-shifter jamming/maintenancebill
Jun 22, 2001 8:08 AM
My ergo-shifters (mostly the right side, the rear shifter) were jamming when shifting to a larger cog. The problem was intermittent and it usually would jam once and then (click-click) work.
I went for the high-tech fix. I peeled back the hood and squirted some dry-lube in there.
It seems to have worked, but I'm concerned because I know that you can wash away stuff with dry lube that maybe should be in there. Any thoughts?

Dunno about the lube, but peeling back the hoods and reinstalling them may have been what fixed your problem. There's a knob sticking out of the rubber on the inside front of the hood that has to be pressed back into place properly so that the thumb button doesn't jam. If that button jams, then all shifting is affected...
nah, been there, done that. That's what I first tried (basedbill

on advice from this board), because I didn't want to be squirting unnecessary stuff. The lube seems to have been necessary; I just hope that I haven't "un-lubed" something else.
Do people take these things apart and overhaul them? Where would I get info about doing this (my Bicycling Magazine fixit book says not to do it)?

I hope the prior suggestions worked, but in case they did not, ergo rebuild info i.e. a reprint of the ergo service manual is available at the Branford bike website: click on Campy only.

At the end of the season overhaul, you can take the hoods off and just push some grease in there with your finger. I've sluiced lots of lube through my C-shifters with no other problems. Well, one other problem. I have to peel the hoods back and wash them with soap and water to get the lube off the rubber - otherwise the hoods can slide around when things get wet.

Yah; Right.
then you can toss the shift lever...C-40

and just buy a new one instead of repairing it for a fraction of the cost.

Campy ergos can be repaired. Brandford Bike will do an entire overhaul for $75.

Most likely caused by a bit of bar tape interferring with the lever. Peel back the hood and make sure the lever is completely unobstructed.

If you do have a "jam" problem gently back the thumb lever and I bet it will "unjam". Again, check the stuff under the hood first.... before tearing into it.
