I am an awful bike mechanic: have lousy spatial thinking and am extremely clumsy. Yet despite this (and maybe partly because of it) I get a tremendous kick of working on my bikes and mastering any sort of mechanical skill. Gives me a hell of a sense of an accomplishment.
It seems just so recently I learned how to fix a flat... Then to get the chain on and off... Next came simple cable and brake adjustments, after that derailleur adjustments... Then I got a used bike with no cables or housing and actually routed all those things myself... And now this: my first overhauled hub. Actually, I am still in process of overhauling it (haven't reinstalled the innards yet - in fact, haven't gotten the new bearings yet), but the scariest part (actually taking it all apart) is over! Yee-ha!
I wonder if anybody else has similar feelings about bike mechanical work.
