Please, take a look at the pic of the brake lever housing in the 3Rensho folder in the link below.

As you see, there is a tear in the metal. Am I mistaken, or is that small area made to be removed for routing of the brake cables? It appears that way to me as the outline is visible on the outside of the lever housing. I looked in the Campy catalogs a fellow CR lister kindly provided me and find no mention of the feature.
Thanks
