Hi,

Will a Quarq Riken (GXP) work with a FSA Mega Exo BB 5000/6000? I have this FSA BB on my Cervelo P2 and it does not seem to fit very well (haven't tighten down too tight yet), but it does not look like it will tighten down enough to take up the play.

Also, when I compare the spindles between the old FSA Gossamer crank and the Quarq the overall length is the same, but the area around spline is different. It looks like a portion of the spline on the Quarq is in the bearing area.

Any help would be much appreciated.

Thanks,

Jeff
