Bought 3 years ago and both original tubes have failed where the valve stem is joined to the tube. Originally changed out 700x32c Kendas with nicer 700x35c Panaracer Pasela TG folding tires, but front was too big for a fender to fit, so I changed it out with a 700x32c Pasela TG. Big change is I flipped the rear wheel and changed from FG to SS and re-installed the rear brake, which I had removed when I was running fixed. Freewheel is an ancient Regina Extra 21T x 1/8" that is about 40 years old. Still have the fixed cog mounted, so I can change back any time I want. Bike now weighs 26.4 lbs as shown with fenders and rack.
