In the morning I decided to grease the hub thoroughly with grease I had got from our swiss friends in Fez. When I pulled the hub apart there were 3 balls broken on the inner ball carrier and one missing from the outer drive side. The grease solved the squeaking noise we had had for over 1000km and things went quite well for the first 30 km including 10 km of climbing up about 400m in elevation. Then at 43.5 km there was a sudden crunch and the pedals would not turn the rear wheel. I pulled the hub apart to find both the drive side bearings completely destroyed plus there was only one pawl of the 4 left intact. It seemed unlikely the bike would go on at all. I re-assembled the hub without all balls in either of the two right (drive side) bearings. We pushed up hill for the next kilometre then amazingly coasted down the hill with no right side bearings. We pushed up a slight hill into a very small village and there was a rummage sale at a house on the roadside and I thought I could see a 20'' wheel. I went in and asked and he said 100 plus 5 dirham. I indicated I needed to check it would fit and although the axle was too short I thought I could bend the frame enough to get it on so I went to pay only to find he meant 150. I had not bargained and it was now a little late, and also no one spoke a word of english. Then to my dismay I found the single sprocket was the wrong pitch for my nine speed chain. Off we went to the local mechanic who happened to be the next building in this very small village. Meanwhile we had 10 kids gawking at our every move. The mechanic was amazingly helpful and stopped work on the motorbike and went to a separate shed where there where old broken bike bits. He changed the axle for one out of another bike and installed a 6 speed screw on cluster and then fitted it to our bike, all for 60 dirham. The whole thing took less than an hour and the bike was going perfectly. No squeaking, no crunching, no out of round wheel, no worries pedalling (in one gear). We carried on, for me the first time for the day I could enjoy the scenery without worrying about the bike. Fantastic!!
