Bad day commuting - mechanical issues
So, I just had my worst day so far with regards to my commute. Just last Sunday, I got my bike tuned up at my LBS, mostly because my shifting was off (I ended up getting new cables & housing and my derailleurs adjusted, among other things). Everything was working perfectly all week...
Then, only 1 mile into my commute on Thursday morning, I got the worst flat I've ever had: while riding up a long hill, a 1-inch screw punctured my rear tire so badly that it came out of the other side of the tube. It was stuck real good and I couldn't pull it out -- I had to unscrew it. I put in a new tube and kept spinning up the hill. After cresting the top of the hill, I shifted into my big ring and the chain overshifted and fell off! Since I just had the derailleur adjusted, this caught me by surprise (I ended up setting the limit screws myself once I got to work, so at least now I know its fixed).
At this point, I really need to haul azz to get to work on time. Hammering along my route, I noticed that my chain was slipping...I figured I must have put the rear tire on crooked or something. Checked it out, but didn't notice any problem and it wasn't that bad, so I just dealt with it. Ended up getting to work just on time with dirty, greasy hands.
Fast forward to the end of the day. Once again, only about 1 mile into my ride home and now my chain is REALLY slipping badly. No matter what gear I'm in, it keeps falling off. I didn't have this problem at all before my flat in the morning, so I'm wondering if I somehow caused it. I try to fix it, but its dark out and it shifts fine when not under load, so I can't figure it out. My 35 minute commute ends up taking me 65 minutes.
When I get home and take a closer look at it, I see that a pin in the chain is BROKEN, and it's just barely holding together. One of the chain links is bent out of shape and that must have been causing my shifting problems. I have no idea how this happened...the chain & cassette are only one month old and have about 100 miles on them.
Anyway, that's my story. Now I need a new chain (I don't have any spare links to fix it). Feel free to add your comments & feedback or just post stories of your own disastrous commutes.
