So my crank arm came off my commuter this morning – serves me right for not checking it was tight I suppose but a painful lesson has been learnt given the body/tarmac interface it resulted in.

I collected up the assorted parts from the road and am pretty sure I can work out the order but was hoping someone can confirm I have it correct.

Its an FSA Gossamer Pro Compact and its the non-chainside arm that sent me sprawling. I have 2 flat washers and a wave washer which fit over the splines and I assume the flat washers sandwich the wave washer and then the crank arm goes on?

Thanks in advance.
