indeed i am trying to do the same thing!
I have a BBright FSA crankset off a 2012 cervelo S5, which i want to use on my cannondale synapse with BB30.
I'm thinking that the bbright spindle is 34mm from center to driveside (like BB30 crank spindles) but 45mm from center to non-driveside (1.1cm longer than BB30 cranks). so then i am assuming i need a 1.1cm spacer!!!?? on the non-driveside... this seems like it would look pretty ugly, and might not even work if there is nothing on the left side of the spindle to retain the spacers. does this make any sense to anyone?
this is correct, the FSA BBright Cranks are BB30 standard on the driveside, so no need to fit any spacers there, there is a gap to fill on the non drive side when fitting the crank to a BB30 frame
the spacer on the non drive side will sit between the bearing a wavy washer and than the crank
doesn't look nice
why not sell the BBRight Crankset, there should be some demand for them as there are very little about (provided this is not the Gossamer ultra heavy Cervelo OEM crank) and get a true BB30 Crankset ?
