Ergo lever spring carrier problem

bdm-<< On dismantling the lever I have found the cause of this fault both times has been that the
index spring carrier (EC-RE111) has cracked - each time in an identical way. It's not the post that
has broken, but the ring itself, just to the left of the post >><BR><BR>

Not uncommon at all. We see many that have been modified with the little shoulders around the post
that they split instead. One thing we do is remove or at least make the 'notch' flatter of the part
EC-RE-057, the little metal cover right above the EC-RE-111. It moves left/right with shifting and
gouges the base of the post, which may cause ot to split where it does. Best thing to do is remove
it as it does nuthin.

Thanks for the comment, Peter. I've re-examined the broken ones and they do show slight notching - although they are more notched on the non-broken side of the post than on the broken side. I wonder if a reason for me having 2 break and some other levers never breaking is that the diameter of the lever body recess in which the spring carrier rotates is rather variable, and that if this diameter (say in my case) is on the large end of its tolerance then the springs may be putting extra stress and strain on the ring of the carrier without it being supported so much by the lever body... Anyway, it still seems funny that campag aren't keen to acknowledge a weakness and start making the part out of a more durable material. They must know they are selling a good number of replacements. It wouldn't add much weight to make it out of steel rather than the light cast alloy they've used.

Agree, we saw our first one in 1998, and have suggested that it be steel rather than aluminum. Kinda
like steel chainring bolts rather than aluminum. Lighter but the steel ones are pretty light to
startwith.
