A friend of mine has been describing a failure mode he gets in various Ergo levers - Veloce, Centaur, and Record. The shifts start ocurring without the click in the lever, first in one, then in more and more positions. It still works, but without the obvious ratchet action. The failure is slow to progress, giving time to plan a rebuild.
While I have seen a bunch of stuff on rebuilding them - hence the need to, I assume - I have never seen any mileage associated with this. His experience is less than 5000 miles to the start of the problem, which I find astounding. In fact, I have a lot more on my Centaur (and my wife's as well) with no hint of such an issue.
Any other experiences out there?
