Sigh....buanged on Jubilee bridge. Luckily was not training on the roads.
Was off saddle and full power gunning up the slope of the bridge in tallest gear and ultra low cadence doing the 8 reps strength training drill and then the LHS crank came off. Heng was strength training and not high speed sprinting. Buanged at around 12kmh.
Caught a flesh wound that split open on my left elbow, took 30 mins to stop the bleed.
Also knocked my head on the floor, helmet got a small dent, sigh.
Really gotta tighten (nearly over torque) the hex screws securing the crank liao. And once every 2 weeks check the screws and crank.
******* dangerous, even got chance of serious injury/death.
This part, the red one + the pedals. Think both a factor of not tightening enough and also off saddle repeated swaying outwards ba. After a period of time just came off esp exercerbated during very high torque with side shear scenario.
I guess the lucky thing is that it could have ended up much much worse, hospitalized etc.
