Well, my shiny new Motomfg steel rear wheel nut socket has arrived, and thank god it has because damn I need new tyres... Anyway, what I don't have is a breaker bar to undo the 230nm nut (which seems VERY tight...). I wondered what size bar you guys use to undo that nut? Seems I can buy one in lengths varying from about 30cm to 100cm, not sure what I'll actually need to get the leverage required? Appreciate any advice.
