Long story short - removed pedal & busted the thread on my left crank arm so now in market for replacement. Brand new one is €40 ish - I'd rather get a used one for much cheaper so will check ebay tonight. However if going new is the route I'd have to take, I'd rather buy a whole new crankset and get new chainrings while I'm at it. I've seen that Decathlon are selling 11spd crankset for €80. https://www.decathlon.co.uk/crankset-105-5800-50-34-1725m-id_8394610.html My bike is set up as 10 speed - would I be able to swap out the current crankset for this one or would I have to swap everything else as well?
