I feel, then, that we have narrowed the questions considerably, to "Or am I just making this up?" Thanks for your patient responses _ I am relieved now to worry about something else, such as what riding habits are chewing up my transmission? Rain, silt, the fact that I take pride in getting up to speed much faster than the adjacent cars when the light changes? And maybe my perception of lost durability boils down to this: The older I get, the more I worry about how smoothly my bike shifts. Shame about getting old.
