A few years ago a friend of mine retired and moved. One night he was talking lovingly about his old bicycle and wanted to give it away. I wasn't sure I wanted a friction shift ten speed but it sounded like a nice bike so I took it. As I researched it, I found I had become the happy owner of a 1970 or 1971 PX10. I contacted him and asked if he would like to sell it since it still had worth. He asked me to ride it instead and then pass it to my kids to ride. I recently took it out to begin the process of getting road worthy again. At first I thought it all original but I have found period modifications. He bought it a few years used and said the original owner changed the brakes. The calipers are universal and the levers dia compe. The deraileurs are the original simplex, the crank stronglite. I thought the hubs were Normandy but as I was trying to find how to pull the bearings this week I found 'Phil' on the hubs. He bought a clincher front so I think the original owner purchased a Phil wood wheel set. I would appreciate any advice on how to service these. Even though it was cared for they are 45 years old. The freewheel looks original. The pedals are French but don't appear original. They are labeled with the English 'L' and 'R' rather than 'G' and 'D'. If some one knows how I confirm English or French thread I'd appreciate the tip. I thought the stem was the original troubled stem but I'm not certain. It's currently stuck. WD40 and some persuasion did not free it. Persuading the bolt broke free the wedge but the stem is still stuck. I'm going to resort to vinegar once I figure out how to pull the wood plug In the bottom and find out whether I need to pull the brakes. I'd hoped to recover the stem but we will see after I extract it. My career is in materials so I have metallurgist friends who can help evaluate it if needed. The shifters and bike pump are campy. The seat is the original brooks. I was pleasantly surprised the seat post was easy to extract and the lube looked new. It was well cared for before hanging up a decade or two. I will probably have to find a shop to pull the crank. The budget didn't stretch far enough to get the crank tool this year.
