Brian, That "someone" was me altzimer boy! I just installed one of these super rare bad boys on my 57-66? Masi Special that will be at Velo Rendevouz in Oct. The bike was discovered in Italy just a few months ago and sports an Agratti bottom bracket and Stronlight steel cottered cranks with a single 51 tooth ring. Installing the damn thing was a bear as the design of the unit is such that tightening each of the two nuts should move the unit in and out ,so to speek, and will therefore center it over and around the chainring. In theory. In reality the threads of the "axel" portion hang up against the holes of the clamp section. Just to get the axel through the clamp when mounting to the seat tube, the holes in the clamp MUST be enlarged with a reamer. ON MY N.O.S. UNIT!!!! AGHHHHHHHHH!!!!!!! Oh yea, by the way, so that the front area of the threads of the axel don't chew up the back of the seat tube, the axel should be filed to a very "open C" up front with a half round dirty old bastard. The problem is the clamp is just not the "right" dimension. All this on MY N.O.S. UNIT!!!!! AGHHHHHHHH!!!!!!!!!!! How priceless WAS that sucker? Please see page31 in catalogo #14 for part # "1039 - GUIDA CATENA". If ya ain't got the original, then order the repro complete one from Chuck Schmidt at Velo Retro.

thanks for reminding me of one of the most traumatic wrenching experiences of my 30 year career. DUHHHHHH.
