Does This Also Need The Small Washer That Comes With The Cranks Or Does It Come With The Washer?
10 Jul 2016
I have the boltstill but the washer has disintegrated...
SJS Customer Service:

This is sold as just the bolt, the washer you are referring to I am assuming is the one that sits between the left hand crank arm and the bottom bracket. This part is available separately and is SJSC part 24989.

Thread Size

Can you confirm what the thread size is for this part.
SJS Customer Service:

The thread on this crank arm fixing bolt is 19.8mm in diameter. If you haver either the Ultegra FC-6800 or 105 FC-5800 cranks then this is the correct fixing bolt, If you don't then it will be a different fixing bolt that you require.
