this saturday, during my morning ride, my left pedal came off.
Not being able to insert it anymore and thinking that it was broken, I tried to insert a new pedal, but mistakenly I put a right pedal.
As a result I have damaged the crank arm and now I need a new left crank.
Where can I buy a new one? Is it possible to buy only the left crank arm? Are there any special instructions for replacement?
I'm still amazed at how the pedal could have come off
