This has always been my "holy grail" bike. The famous bike presented by Ernesto Colnago to Pope John Paul II in 1979; a gold-plated Colnago Mexico:

Of course, there is only one true "Pope Bike". It resides in the Colnago museum in Milano, Italy. Colnago made a number of these commemorative gold-plated bikes. Here is my newly refinished "holy grail" gold-plated Colnago Mexico Oro bicycle, complete with fresh lacquered 24kt gold plating and NOS components:
Pat. 78 rear derailleur with alloy bolts, Regina Record Oro drilled chain:
Four hole 1979 only front derailleur. Campagnolo Mexico Ernesto Colnago pantographed crankset with milled spiders. Black anodized alloy chain ring bolts hold the Ernesto Colnago pantographed chain ring:
