I don't think of it as a "walk of shame" any more. It should be considered a "walk of fame" or some such. I've ridden so far that things have worn out, or in a few cases defective manufacturing showed up. Tread delaminated from the tire? Not my fault, the tire wasn't worn out. Busted crank? Hey, I wore that out! Bearing wore out and pedal came apart? Ditto. Seatpost cracked and folded? Double ditto, how many people put 50,000 miles on a seatpost? Be proud of riding so far and so hard!
