Played with the bull, got the horns.
Trying to get every last meter out of my chain/cassette given the current parts situation. Turns out the last meter was about 350 meters short of tonight's destination
Lights were turning green so I did the right thing and hung at the back of the line. Clicked the next gear, stood up to stay with cars and the chain skipped. Dumped my arse on the tarmac, in the middle of the intersection.
It shocked the two pedestrians crossing the road more than it did me. And the lady turning right thought I came out from under the ute I was following.
The confession part comes from not paying attention to my drive train telling me it was cooked three or four weeks ago
