My bike can't keep up with me even though it's a lot younger.

Good for you. Just means you're riding lots.

How do you wear out Tyres? Mine get ripped to shreds before the Rubber wears out--And I am replacing one tyre today on the Pinnie due to the puncture I got one mile from home last Sunday. Repaired the tube but the hole was a bit of a ragged tear and not a thorn. Pumped back up and the side wall went bang. Only done a few hundred miles on that one.

But the original Michelin Pro 2's that I bought in 2007 and took off the bike in 2008 as they were getting a bit cut up and kept as spares in the shed- Still have good rubber on them so have been pressed back into service. Just hope they last till I get a replacement tyre. They have done on previous occasions--About 5 in fact.

Great!! Just don't flip that stem or your bike will have you in the poor house.

Riding thousands of miles?

(Actually, i am sure they have some miles left but I prefer to err on the side of caution.)

Sorry, don't understand. Why would I flip the stem and why, if I did, would it put me in the poor house?

I ride a fixed gear, and I'm on my fifth 1/8-inch chain and third rear cog, and I still haven't spent what it would have cost to replace a 10sp cassette and chain!

Mine's an eight speed and costs $44.00. Going to install it myself.

My wife surprised me by wanting to see "Premium Rush", the movie about New York Bicycle Messengers. We both enjoyed it very much. Lots of action and the bad guy (a crooked cop) almost stole the show.

Just exactly how crooked was he??
I saw the movie also and enjoyed it. I didn't see in the credits but was that Danny MacAskill doing stunts?

Not sure if you would categorize him so much as crooked as psychopathic. Well, actually both.
Don't know anything about stunt men but there were certainly a sufficient number of stunts.

Got bike back today. Turns out I did not need to replace the rear cogset after all. The derailleur was slightly bent and needed adjustment. Should have realized that could have been the problem. Think I will try even harder to avoid cross-gearing as I think that may have been what caused it to be pulled out of line. Am extremely careful about subjecting the derailleur to accidental knocks.
