I have almost 1500 miles on mine since end of January
all working hard, and no bike probs at all (my bike is my transportation and my grandkids taxi)
mind you, I changed wheels for better/heavier that I had, and upgraded crank and headset bearings as well
the parts I swapped were upgraded over time (3+ yrs), and came from my Schwinn Jaguar when I switched to the stretch
Great to know; if I indeed buy a new bike, i'll feel better about the micargi.
be seeing you
