FSA Tempo crankset is not compatible with FSA Vero I just purchased a new FSA Tempo Adventure JIS crankset - 46/30 to replace the FSA Vero Compact 50/34 JIS crankset on my 2018 Cannondale Synapse Sora 9 speed as I need lower gearing. Both are shown as FSA "Road" and should be compatible. But they are not... On the Vero, the interface to the BB sits slightly **above** the plane of the inner chain ring. On the Tempo, the interface to the BB sits a few mm **below** the plane of the inner chain ring. Net result is that the chain rings of the Tempo are closer in to the frame, and actually touch the chain stay so cannot be fitted. Does anyone know if there is a way to to overcome this problem? Maybe there is there a replacement BB that would compensate for the movement of the Tempo cranks closer in to the frame? ![FSA Vero]( ![FSA Tempo](

Many thanks for the advice everybody, especially @ojs

I'll need to get a BB with a longer axle.

According to FSA tech support, the Vero uses a 110.5 axle length for a 44mm chainline, and the Tempo requires a 118 axle length for a 44mm chainline.
