Checking in on 2017 S-Works users: has anybody fitted one on a true PF30 frame (not a Specialized), ideally with a power meter?

On the old (2016 and before) version, you needed to dremel the lock ring down somewhat and use different spacers, otherwise it came into contact with the bearing cups.

Thanks! Did you have any issues with the crank dragging on the PF30 cups? That used to be an issue with the old one

BB is a XD15 ceramic... they took 2000km to start spinning more freely...

I'm curious about this myself, any chance the 2017 crankset works with a BBright PF30 setup?

Pretty definitely not - axle is too short.

@elfuinha: did you get a manual with the crankset? Wondering which side the preload adjuster goes on - I would assume on the non-drive side, and whether to fit any micro spacers on the drive side.

On the PFBB30 if i'm not mistaken just a 2,5mm spacer, the preload doesn't fit on the drive side there is no spacer.

when fitted the crank didn't spin...

I'm using XD-15 ceramic torqtite from ENDURO as the BB.

Just to make sure I understand correctly:
- No preload adjuster, instead
- 2.5mm spacer on the non-drive side?

For those who installed the new 2017 crankset with the carbon spider on an SL5 sworks, are you guys using the bearing dust covers along with the preload adjuster as directed on the instructions? I read somewhere earlier someoone was foregoing the preload adjuster and using a wave washer and 3mm spacer instead?

Does anyone know the torque spec for the 2017 S-works crankarms? I now have two sets but I can't find the recommended torque spec for the new style crankarms. I know the old style was 33n/m with the specail tool... no I can't find any manuals on the new arms anywhere And the manual Specialized put in the box with the new arms is actually the pre-2017 manual). The arms spin freely around 15-20n/m but if I get up to 30n/m they seems to be more drag. Installs are in a sworks shiv and sworks venge both with the pressfit specd bearings. Thx much.
