That's what I thought you'd all say. But that's ok, because you're all very right.

I guess I'm slightly concerned with the chainring/cassette combo along with the chain mostly because this is a used bike. I have, sadly, only put 436 miles on it so far, but I forget the previous mileage on it. I need to dig up the computer that came on it (passed it on to my inlaws) and figure that out.

It's an '06 Specialized Roubaix. I feel the cassette looks good, but the big chainring right behind the crank arm shows shorter teeth than all the others. I assume it gets a lot of grab in the spot from the force of the pedal when shifting under any sort of load.

I'm also concerned about the tires because they're cheapie bontragers that say "inflate to 100 psi" on the side. I ran 100 psi in the rear and it felt and looked like I was about to get a flat any moment. I probably need to replace those just because....
