Say it ain't so: The Assploded Bike Parts Picture Thread.

A clean break on both the top tube & down tube. Metal fatigue is real.

paging @sleve_mcdichael .
looks like more ductile failure on the TT when it let got after the fatigue and overload on the DT

Paint flaking on the top tube is consistent with more ductile failure (the metal behaved plastically and the polymer paint didn’t :grinning_face:)

maybe no one taught him how to use the couplers and he became impatient.

Maybe sometimes shit just happens

everything has an end, 89k miles is more than enough to get out of a frame ATMO

Did it happen while it was locked? Because that looks unrideable.

my guess is hobo/bum bike (whatever the current term is) and probably in active use

Is it just a weird angle or does it look like the wheel won’t turn because the tire is hitting the downtube?

You’d think the twisted top tube would make up for the bent fork

I don’t recall, I saw it in passing but it didn’t look particularly derelict

A slight interruption of this afternoon’s ride:

I was sailing down 72nd street at ~20mph and the rear inner tube exploded just as I reached Flavel St. I didn’t even need to pop the rear tire off to check the extent of the damage because the blowout (and subsequent emergency braking) had popped the tire completely off the rim.

I did have a spare inner tube, but I was literally 75 feet away from the #19 bus stop and a westbound #19 was about a block away, so instead of using my spare tube and finishing the ride I hopped the bus home and took out the trash. Tomorrow will be equally as warm, so nothing of value was lost.
