I need a replacement left crank bolt for a FSA Gossamer compact double. The part number from FSA is ML 129 and it looks a lot like this bolt (the ML 131). The only visual difference is the FSA is printed in a flat line on the bolt head, and the ML 131 had the FSA logo going around the circumference of the bolt head. Are the two bolts interchangeable? I'm having a really tough time finding the ML 129. Any suggestions?

It appears to be the correct bolt for your Gossamer cranks.

Did a little more research and don't believe this is the correct bolt. the one I'm looking for is size M18 and this one appears to be M12.
Thanks for the reply.

Looking at BTI you need the FS-0016 which yes is an 18mm.
