new frame rumors for 2023?

[blaugrana]

I've dealt with PF30 creak before. But yes. BSA is back. Ai is gone as well

I don’t think the regular SSEvo ever had the Ai offset.

I don’t understand the reluctance to go T47. If they’re sticking with 68mm wide BBs, they can just go T47e. No tool purchase issues that way. Seems like an accountant had their hand in that decision. BSA probably improves margins on complete bikes by a dollar or two.

Yeah you're right the SSEvo didn't have Ai. The Carbon Topstone and the SSEvo CX did.

As to why they did BSA and not T47, beats me. I have a t47 bike and its the shit.

I've got 2 bikes running with BSA30 bottom brackets and there's no problems with either of them, BSA lets you run any crank you want as long as the spindle is long enough.

The move from PF30 to BSA has probably killed off Cannondale's own cranksets for good and bikes will be specced with standard Shimano/Sram cranks which is a shame. I was always a fan of the look and the function of the high end Cannondale cranksets.

I find it a shame as well: Cannondale cranks are quite good, and very light as well. And if I understand correctly, the PF30/BB30 bearing size isn't particularly problematic (unlike trying to put 30mm axles on BB68 bottom brackets), the issues have more to do with Cannondale's tolerances being inconsistent.

I suppose the move away from pressfit has a lot to do with many bike reviewers automatically considering it a negative and associating it with creaking, while generally looking positively at anything threaded. Meanwhile, almost every modern hub uses pressed in cartridge bearings and nobody cares. Actually the only time I experienced creaks due to poor bearing interfaces was in a hub with terrible tolerances, while all my pressfit BBs (including a BB30 Cannondale) have been fine.

They've been killed off on high end road bike spec anyway. When Sram 12 speed and their (supposedly) proprietary chainrings came along Sram demanded that the full system was specced or nothing at all. It looks like Shimano have followed suit with their 12 speed offerings as well.

Some Canyon bikes were assembled with Rotor Cranks and PM, because Shimano wasn´t able to supply Dura Ace 12 speed.
Also, Canyon uses 4iiii PMs on their Ultegra Di2 bikes instead of Shimano.

Aren't the bearings always "pressed in"? As in, take any tread-together bottom bracket, or even one-piece BB like BBInfinite, and the bearings are pressed into an (usually) alloy cup at either end.

So I don't think it's the bearings being pressed in that is an issue. It's the crappy plastic cups being fitted into a not-quite-straight carbon shell, creating bearing misalignment, etc. etc.

If you think about it, there are just so many issues that have been created by having carbon parts in the wrong places... Like yes, you can make a carbon BB shell, but in a mass-production scenario a machined metal piece is better. And yes, you can have a carbon braking surface for rim brakes, but an alloy one performs better in the vast majority of cases (to a point where we then collectively decided to ditch the whole rim brake thing altogether!). And yes, you can replace steel spokes with carbon, but their failure mode is not... nice.

Yes, pretty much (unless they are loose ball cup and cone bearings). But threaded carbon frames require an a metal insert anyway, so I don't see how that is an inherently superior option (carbon frame - threaded metal insert - threaded metal cup - pressed in bearing). But pressfit cups can be metal as well, if plastic is the problem, and having a threaded interface doesn't really solve alignment. How much of a disaster manufacturing tolerances are is quite hard to tell, because it seems that most third parties pointing out the issues with BBs from traditional manufacturers are trying to sell their own solutions (Hambini, BBInfinite...), but a well aligned one piece metal insert to which replaceable bearings are pressed does seem like a sound idea.

Is Bianchi still updating any of their bikes this year?

They've been pretty much off the radar if you ask me .

Would love to see them catch up, but somehow my expectations are low.

[TobinHatesYou]

Bianchi dropped hints of an XR5 when the Specialissima was announced.

Looks like we've got cannondale's sworks soon?

Can't see the pics...

There's no pics. They're applying for a trademark.

Cannondale is attempting to trademark "Lab 71"

[Karvalo]

It's strange that they're only just getting around to this. About 3 generations of Synapse ago they did a special edition '71' top spec model, then the year after had a few mid range bikes with '71' logos then it disappeared completely.

Unlike S-Works it's also, I dunno, not catchy or self evident. Lab 71 sounds like the kinda thing that'll need to be explained to everyone who's hearing it for the first time.

Trek releasing a new model? Or new year Emonda maybe.

The current Emonda is a pig IMO, so I wouldn't be surprised if they fasttracked a new release one year early. The brands also seem perfectly fine with paper-launching products months ahead of real-world availability.

The fork looks pretty skinny and it looks like it's using the same RCS stem as the Domane.

Also a small chance that they're releasing an e-Emonda of some sort.
