-Got my Dunlop roadsmart tire put on.
-New sprockets by driven (44R/15F... stock "s" gearing)
-520 XSO chain.
My other chain had the red dust of death, the chain was stretched like a mother. It would go from 1/2 inch of freeplay to 5 inches in some spots! My bike was getting very loud, it vibrated much, and the pulsing in the first two gears was horrible. It was literally lurching badly. The sprockets were fine but I replaced them anyway.
It rides like a dream! I am glad I replaced bad components and I feel much safer as a result.
-The other tire.. a continental road attack, lasted
8568 miles. It had just gotten worn down to the replacement marker, though it could have gone much more if I decided to (but it would be illegal.) I had only gone to palomar mountain twice on that tire so approximately 8500 miles of straight freeway commuting. The tread on the sides was barely touched.
-My original chain lasted
13818 miles.
