Not that great I'm afraid! I've came surprised with the stock seatpost weight for such an aero design:forklifter wrote: ↑Mon Jan 09, 2023 11:24 pmMaybe some potential weight loss:

Only to consider if you need less setback I guess

- aeropost 2 or 3 being weighed? cut/uncut?
-145g seat post alone + paraphanelia = 219g?
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.Lina wrote: ↑Mon Jan 16, 2023 2:50 pmBearings have seals for a reason.

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.naavt wrote: ↑Mon Jan 16, 2023 3:06 pmC-Bear bearings have seals.

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?
