He wasn't tightening was he?
The left pedal you turn clockwise to undo if you're on the same side as the pedal.
Or stay on the drive side and it's lefty loosy, righty tighty
Cheap Allen socket if it shattered 😳
No, definitely doing it correctly .... drive side pedal was a bugger too, but thankfully that did come off as I didn't fancy buying all new kit for that. It's the left side that's not budging.
