Dear Greg, in reply to your question about the correction factor for center ing the removal tool for thicker dia. bar end corks of Italian manufacture, contrary to popular belief and common sense, the equation is not std Frenc h dia X Italian dia. / 100 added to std dia., but theoretic hight of the ti de at Milan / 3.1416 X circumference of bar inner dia. This is mainly due t o softer and cheaper shiny material found on Italian bikes which has a rand om distortion factor. In other words, oil it and whack it in with a croquet mallet. As to mixing French and Italian corks, we have found this to be da ngerous, as Ialian corks having a lower density and reliabilty factor, on s teep descents air pressure increase within the bars can cause the Italian c ork to shoot out of the bars with a bang which can scare the pants off you, and badly upset the handling of your bike. Regarding English corks, little data is available, as the vinyards of England total about twenty five vines. One assumes that Vintage port corks with shims is the normal p rocedure.

And with that I shall refrain from further discussion unless offlist of thi s topic, lest I incur the wrath of the listmeister. Nevertheless, fun apart , bar end corks are not a joke, they really were very commonly used over he re. And I fit them to all my pre 1970 bikes.
