Bit of help needed here guys as I am stumped.
I have just bought a brand new (removed from new bike and sold to me) FSA Carbon Team Issue cranskset.
I bought it to put on my 2010 S-Works stumpy that uses a Shimano BB-91 press-fit adapter that needs an axle of 24mm (which both Shimano, and this particular FSA crankset both have).
The BB91 utilises a small plastic spacer that slides down the axle towards the rings which you fit before using the BB91 (this has been done and is fitted).
The axle went straight through and came out the other side perfectly (i.e., the ‘splines’ end right at the BB.
So this has ruled out any BB91/crankset incompatibility issues.
PERFECT
Oh No...
I greased the splines on the axle and attached the left crank arm and started to tighten away as per usual.
However.
The crank is about 5mm away from the BB/End of the splined section of axle.
Now believe me, I have tightened this up SUPER tight, I am aware of FSA’s unusually large torque settings for these, however I DO NOT want strip threads, bugger/snap the bolt etc.
My questions are:
A) How do I overcome this? Am I not fitting the left crank arm correctly?
B) Is there supposed to be some sort of spacer, that goes on before the left crank arm?
C) Should the left arm tighten up to the ‘end’ of the splined section of the axle?
I have some photos to show you the situation:
I would REALLY appreciate any help on this.
