Bottom Bracket - Expected Life Span?
I upgraded to a new Dura Ace ten speed drive train last April....now have 4,968 miles on the bottom bracket and it is now clicking which I am interpreting to be a problem. Have verified that nothing is loose. Should I be expecting a longer life span than this? Or is this "normal"?
If I should be expecting a life span of 5,000 miles +/-, than it would seem to me that I should be upgrading to a Phill Wood bottom bracket, or something of that caliber.
As an aside, I am 6'1" and 210 lbs, and am apparently very hard on bikes....my ten speed chains are always "all done" at 2,000 miles....I commute 24 miles R/T every day and usually do a 60-80 mile ride on 2 to 3 Saturdays a month.
