Installation Mega Exo - please help

[Rick]

Hi all

 

I am installing an FSL SL-K light. Frame is 2011 roubaix sl3. I have removed my shimano BB and installed the Mega Exo. The shimano had a spacer between the BB and the frame on the drive side. The Mega Exo came with a wave washer which goes on the opposite side but without any spacers. I'm not sure if I should use the spacer I removed on the drive side??

I hooked the chain up to test the alignment and there is rubbing on the derailleur which would suggest the spacer should be there, or i must adjust the derailleur.

 

This is my first attempt at this and it's proving quite confusing.

I watched a video which stated 2 drive side and 1 non-drive spacers are required for 68mm shell. 73mm shell requires only 1 drive-side spacer.

The installation manual on the FSA site makes no mention of any spacers though

 

Any help will be hugely appreciated
