    BBright Adapter

    I currently have a 2011 R3 frame that i would like to put my Ultegra drivetrain onto. I have the BBright adapter but nowhere can i find directions on how to install it? Do i need to use loctite? What way to u place it in the frame - the ends of the adapter are different, so what end goes on the drive side? Thanks. C.

    Read Damon's post in the thread about the S5. It gives all the detail for installing the BB cup adaptor for Campagnolo chainsets.

    Type the words LOCTITE and BBRIGHT into the search bar at upper right hand corner of this web page and you will find the multiple threads that have already been started on this topic.

    You will need to use Loctite 641 or 609 as well as Loctite primer.

    Hi cbtriplec,

    Here's a previous thread with details: http://forums.cervelo.com/forums/p/8324/57692.aspx

    Basically,

    1. Use LocTite RC609 between the frame and cups. Just follow the directions that come with the LocTite.
    2. For your Shimano-compatible bottom bracket, put the sticky-outy part on the right side, and the flush part on the left side.
    3. Fully assemble your cranks (include the red rubber seals, one on each side). Adjust the bearing preload as usual. This helps everything stay in place while the LocTite hardens.

    Enjoy your new R3!

    Hi there, If you don't have anything and have to start a fresh, Is either of the 2 types of Loctite preferable or is one better than the other? Would you happen to know which type of primer as there seem to be more than one ? Many thanks

    Hi bigmac,

    We recommend LocTite 641. Activator 7471 or 7649 speeds curing time. LocTite's PDF info sheet is here: https://tds.us.henkel.com//NA/UT/HNAUTTDS.nsf/web/29FD0B44C6E02909882571870000D85E/$File/641-EN.pdf 

    Our retailers have also reported success with LocTite RC609 and 608, with and without the primer/activator.

    Re: BBright Adapter

    So right....i thought i'd dig up this thread because i've just about to start re building my R5 to race on this season and had been having problems with the Campag pressfit cups moving.

     In all fairness i didn't use the correct stuff when i installed the Campag adapters and the drive side cup moved a bit. I've now bought Loctite 641 and Loctite Activator 7471.

    I am reading here also that maybe Loctite 609 is better ? I don't want to go down the road of using the 641 and it not working and then having to do it all again with 609.

    Does anyone have any experience with this and can advise ?

    Thanks

    Stevie K,

    I used Loctite 609 back in mid August on my R3.  Since then, I've put on over 4,000 miles / 6,400+ km and have not experienced any problems at all.  From the tech docs I have from Loctite, the only difference is that 609 is used for diametral clearance (gaps) up to 0.005"/0.1mm, while 641 is up to 0.006"/0.15mm... those are both pretty small gaps, so I'm sure either will work fine.  Below is a link to the tech data. Good luck.

    I had poor results using 641 w/ primer, so I had to use the higher strength 609 w/primer. I have had no problems since (BBRight Campagnolo cups on a 2011 R5). Be sure to use a bearing press or headset press to set the cups and leave the press in overnight for best results.EM3

    Re: BBright Adapter

    Damon,

    Looking at P5.  I have a Dura Ace SRM that I would like to use.  I would need the BBRight adapter.  If in the future I change to a Rotor 3D+ crank, can I remove the adapter without damaging the frame?

    Re: BBright Adapter

    Yep. Might take some ballistic persuasion, but just hold the frame in your lap.

    Cheers, 

    Damon

    Re: BBright Adapter

    Ok guys....so right. I've got a friend of mine who is a mechanic to do this BBright Adaper install to make sure its right. I've gone with the Loctite 641 for 2 reasons, a. I read Damon recommend it on here, and b. I had already bought it. I had since read 609 was better but i've gone for it.

    Firstly, we cleaned the bottom bracket on the frame and the cup with an alcohol based wipe. Loctite Activator 7471 was then sprayed on the frame and the cup and allowed to dry. We repeated this process a second time. Then we generously applied the 641 to both the frame and the cup as per pic below...

    The cup was inserted, the mechanic did note that the cup does not become a really snug fit until the last 5mm or so was inserted. The cups were then pressed in firmly and a press and have been left for 24 hours to "set". As per pic below...

    How does that look to you guys who've done this ? I am hoping this is the end to the problems with movement in the adapter

    I don't see anything wrong with the steps you took, nor with how everything looks.  As noted on an earlier reply by EM3, he had poor results with Loctite 641, but only some Kms on the road will reveal what happens with your setup.  Remember, every frame is slightly different and could have either a bit more or less material on that BB shell, so gaps between the cups/adapters could vary from bike to bike.  There is always Loctite 609 if it doesn't work. Good luck.

    Agreed. Just did this on a new S5, and it was a very tight fit. Used 609, but this seems like overkill given how tough it was to press in. We'll see.
