You can tell I'm new to biking - I thought all that jagged metal around my rear rim was decorative. Strangely, Mavic didn't put any on the front wheel....and I can see most of the tire bead exposed on the back; I'm amazed that tire stayed on.
Problems and dilemmas though. This is a really, really ratty road /race bike - cost me $40 on e-bay. BUT, it's my bike (if you know what I mean) AND, I told it that if it made it from London to Paris intact (it did), I'd spare it the dump. A promise is a promise, I suppose PLUS, I've really grown to like the 'feel' of the frame, rust splotched and paint chipped though it is.
I could buy another wheel but the groupset is an obsolete Shimano (RX-100) with a 7 speed (FH-A550) freehub (I guess). I'm not optimistic about finding a compatible wheel. My US biker pal is encouraging me to get a new rim and rebuild the wheel. The LBS will do trueing at reasonable cost - but is this a suitable project for a newbie? Does anyone have other suggestion?
