sorry to hear about your misfortune. im just curious as to how the dent got in the tank? there doesnt seem to be any scratches on it.
also this is why i have trained myself to NOT use my rear brake. its too hard to control it in an emergency. there was an interview in cycle world of some racer. he was testing abs brakes. said he never uses the rear brake on the track or otherwise. i have since taken his advice and probably saved a crash. during an emergency it is very hard to have contol over the brake foot.
heal up and get that bike fixed.
I honestly think my hand/wrist is what put dent in tank ? Other than that I have no idea ?
