so I accidentally screwed the wrong side pedal into my left hand crankarm on my Giant Defy 3 2014, and I have been looking to buy a replacement part myself and get a mechanic to install it.
I am wondering what would be compatible with the original Sora groupset components? I haven't been able to find just a crankarm, so I am looking to buy a crankset.
I can get a Shimano Sora Double 3550 9 Speed Chainset for 40GBP.
Would other 9 speed cranksets work?
What other left hand crankarms would be compatible?
