Bike porn

this happened to someone on this very forum.
if i remember right, he had really tight clearance like that Kenevans with a front brake.
front braking flexed the fork enough for it to jam hard against the downtube and buckaroo him clean off.
for the life of me i cannot remember where or what the name of the thread was.

This would be even more likely with a drilled track fork as the round blades and design were not made to deal with brake stresses.
