Cosmic Pro Carbon v Speed 40C v Attack - choice?

[pdlpsher1]

I would pursue the Boras. The price premium of the Speed 40 doesn’t make sense. I have both the USB and Cult bearings. In the hands and on the bike stand there’s a big difference in friction between the two (the Cult spins much longer). The big question is how much free speed does that translate to on the road. I cannot really say. If price is a concern the USB is excellent. I have the Bora One 50s and the Bora Ultra 35s, both without the AC3. Braking is superb in the dry but not too good in the wet.
