Using the Token campy BB...really good.

Conceptually, any thread together should work well...note no place for c-clip vs campy oem bb cups.

If you aleeady have C-Bear you should try it, they are good quality. If it starts creaking you can change it later. But it should be ok. It is not some rule every pressfit creaks.

Manage to find a Token one on an Italian bike store. Campy SR CULT bearings are known for having dragging seals. I'm thinking on fitting the C-Bear ones on the Token unit. Let's hope they fit.

C-Bear does not run seals or has a contactless seal?

They have seals but are much more free running than CULT bearings. Don't really know why though.

Maybe some potential weight loss:

Not that great I'm afraid! I've came surprised with the stock seatpost weight for such an aero design:

Only to consider if you need less setback I guess

thanks for this - a few Qs
- aeropost 2 or 3 being weighed? cut/uncut?
-145g seat post alone + paraphanelia = 219g?

R: Aeropost 3 - Uncut

-145g seat post alone + paraphanelia = 219g?

R: That's right. The heaviest thing here is the hardware by comparison.

Bearings have seals for a reason. Especially in dirty environments, which bottom brackets definitely are. Even if the bike is only ridden in dry conditions. And the seal drag on bearings is so small that it's completely negligible. Sure the bearing won't spin freely when you spin it, but that doesn't mean it's robbing you of watts. And after some use the bearing with good seals will be rolling better than the one that's been ground up with dirt in there because it has no seals.

C-Bear bearings have seals. They just don't drag as much and are known to be easier spinning than CULT ones.

Seals that don't drag as much have less protection. And no, the CULT bearing seals will not steal you of watts compared to other sealed bearings. Spinning bearings when they're not under load is completely irrelevant to how they'll perform under load. At most you'll notice if something is really wrong in the setup when it doesn't want to spin at all. And in those conditions a bearing with less sealing or no seals is going to seem like it spins forever. But under load while you're pedaling the difference is so small that unless you're in a TT race where every single watt matters it's not worth it. And you'll need new bearings for every race if you want that marginal gain. But there is a downside to less sealed bearings, which is that they get worn much faster as dirt gets into the bearing and eats it. So while it might be marginally, and the margin is really small, faster out of the package it will be slower after a few weeks of riding.

Unless you're prepared to change the bearings often then you'll most likely get better performance on average from the more sealed bearings. Especially since the CULT bearings are quite good and last forever. In part thanks to the seals.

My bike is finally on the assembling line as I write these words :)

Became aware that the frame interface mounting plate is only adapted for Di2, not EPS. For the time being the mechanic screwed the EPS plate on top of the mounting plate, but in the long run I would like to "clean" that up.

Do you guys know if Look makes a frame mounting plate specific for EPS?
