(interestingly, my cups only came with the o-rings, but no seals...your pics appear to display a lip seal against the frame?)

the cups pictured above are "eps compatible", i believe there is a plastic tube that spans across the new lips facing inboard. this is merely to keep the wires off the bb axle. these cups supercede the old cups.

Permon, the wave washer and the RogueMechanic "fix" has nothing to do with it...this is simply a BBRIght Campy Press Fit issue. It sounds like your LBS is engaging in due diligence to try and solve the issues but I noticed two errors they made.

First, take off rubber o-rings and lip-seals from the cups before installing as they may get snagged in the compound (in between frame and cup) when inserting cups and yield an uneven surface (interestingly, my cups only came with the o-rings, but no seals...your pics appear to display a lip seal against the frame?). Second, Loctite 638 is too thick for this application and as others have indicated, it may be simply oozing out from between the gap when you press in your cups, leaving you with limited compound to actually bond. Use 609 for best results. Begin by applying liberal amounts of primer and be sure to let dry for at least 30-60 minutes, then apply liberal amounts of 609 both on cups and frame. Use a bearing press to fit the cups and leave the press fitted for at least 24 hours (this is very important). Do not let your shop install using the actual cranks as a press....this may result in Loctite oozing into your bearings, leaving you with another problem. There are no shortcuts...the bearing press is required.

Given that your LBS has already tried this a couple of times and failed I suspect there will be lots of compound residue in your BB shell and on your cups...that will need to be cleaned thoroughly (use acetone) before trying to reinstall.

I have installed BBiright cups on many Cervelos and found that my initial use of 641 (what Cervelo was initially recommending when BBRIght was first introduced) was simply not sufficient and the cups found their way loose after a few ride, however, others have had success with 641. I have not had any failures after using 609.

Good luck,

Hi,

The problem IMHO is not going to come from the heat resistance of carbon fibre but from the adhesive that was used to bond the shell to the frame.

On the bright side: it does no longer move so why not leave it be for the time being?

Ciao,

So, I bought the Loctite 609 + activator.
I disassmbled the cranks and tried to remove the cups.....well, it seems to me, like it is rock solid and cups are not going out Uff.
I am going to take it to the LBS to disassemble it, but I am so scared that cups are bonded so strong now, that they will not get out.
I checked the technical documentation for Locite 638 (used by LBS) and found out that it is possible to disassamble bonded parts under one condition.....temperature of 250 °C.
No I talked to a friend of mine who has a company selling carbon fibres. He said, that 250°C could be OK for carbon fiber, but it will probably get softer and should not be mechanically stressed. Not good, because there is need to take cups out of the frame mechanically.
Other way around is to use solvent for to liquefy the acrylat glue. This could be quite safe (carbon fiber should resist it w/o any problem) BUT, the solvent would need to get deep in the bond.....which could be a problem as the fit (cup + frame) was quite tight.

Any advises guys?

I am so *f##k* up by all of this. I just wanted to have a new frame, now I have a BIG problem:(

Easy fix, heat it up, let it cool and pop it out.
The loctite's grip fails when heated, not just when hot.
250C is easily acheived with a heat gun on a low setting.
Obviously heat from the center.

Also, the loctite is there to tighthen tolerance, it does not have shear strength so once you move the cup any it's entire purpose is destroyed and it has not holding strength.

out of curiousity, in what shape is the BB carbon shell after all this ?
