Ultra Torque: Cranks don't spin smoothly?
Comments

Lots could have gone wrong, we need more info:
is this a new frame, has the BB been faced?
Have you put the spacers in correctly?
Is the weather sealing 'O' rings lubed?
Is it aligned correctly?--

It is a new Colnago Extreme C and not been faced - doesn't look like it needs it, as its a Ti BB insert and there's no paint / carbon on it
Spacers are in - the wave washer, aligned (180 degrees) Didn't lube the O rings, no mention of that in the instructions - the ones on the cups?0 -
Think you'll find it's just friction between the O ring seals in the bearing cups and the crank axles.
New caranks usually have some grease on them, hence the moulded plastic sleeves which you discard. Might be worth re-assembling them with a bit more grease.
My similar cranks only spin for one turn and are not like previous set-ups with a separate bottom bracket where the cranks would spin for a number of revolutions.

External bearing BBs don't spin like the old days of caged ball BBs where a quick shove and they'd spin for ages - it's drag from the bearing seals.Make mine an Italian, with Campagnolo on the side..0

Thanks all, thought I'd mucked up installation and damaged the frame / cranks.
Am I right in assuming that frame didn't need facing cos its a Titanium BB shell?0
