I'm sure this is all routine for most of you, but I'm feeling pretty good about my latest bike repairs. I'm trying to reduce my reliance on the local bike shop for repairs and also save some money...
My chain was falling off the front chainring, so I figured I needed a new chain and possibly a new cassette. So I ordered a chain and cassette and used my cheapo bike repair toolset and successfully removed the cassette and cleaned it in Simple Green (now it's all shiny!! ). It looked like it was not too worn, so I decided to re-install it with a new chain and see how it worked.
The rear cassette seemed fine, but now the new chain was slipping off the middle chainring. It didn't slip off the small or big chainring, so I figured that I had worn down the middle chainring too much. (My chain was *really* stretched - over an inch longer than it was supposed to be.) I wanted to ride my bike today, so I decided to pay too much at the LBS for an Ultegra middle chainring, the only one they had in stock.
I successfully removed the crank, took apart the chainrings, and put it all back together, and now it doesn't seem to be slipping anymore! (I need to go for a bit of a longer ride to make sure it's all fixed, but it seems good so far.)
Anyway, all that just to say that I'm feeling more confident about performing my own bike repairs. Let's just see if my bike doesn't fall apart tomorrow!! (I don't have a torque wrench, so I'm not too sure about the tension on the chainring bolts and cranks...)
