I'm no DIY or bike expert, so please advise in easy language!!
I was riding my Giant Warp DS2 last night, and the right crank arm decided to just come off, leaving me stranded 15 miles out in the stix.....finally got home and saw that the Crank bolt nut has sheared off. Please see this photo.
If I'm right in my thinking (please tell me if I'm wrong), I need to get the remains of this nut out, and replace it with a new crank bolt.
Any ideas on how to get this out? It looks solid. I don't know whether to try drilling it, or if there is another method. If I need to drill it, what drill bit? Stupid question, but I'm useless at DIY etc.
Thanks in advance.
