    SRAM Red / BBRight / S5

    Hey, I know this has been asked before but not lately so I thought there might have been some new developments with the pending S5. As far as SRAM crankset compatibility goes with the BBRight setup from what I understand the S900/S975 PM crank work natively. Will the standard BB30 Sram Red crank work with some adaptor ? The BBRight website seems to say all GXP cranksets work so I presmue the Sram Red in GXP form will work ? On the campy side, a standard Super Record crank will work with adaptors? thanks for your time.

    Correct. http://bbright.net/supportingbrands.aspx has the specifics.

    Re: SRAM Red / BBRight / S5

    Damon, excuse me if your link answered this question but I couldn't see what I needed.

     What are one's options for Campagnolo cranks on the S5? Would my compact Chorus work with some kind of adaptation, if so what? Or would could I use to work nicely?

    Thank you.

    Hi Julian13,

    Your Chorus cranks will work on any BBright frame if they're the Ultra-Torque spindle. You'll want Campy's OS cups to fit in the frame and hold your crank's bearings. You'll want Campy part number IC11-CER51. (Cervelo retailers can order these cups with Cervelo part number BB-P-CAM-BBRI).

    LocTite the cups into the frame using LocTite 609 or similar, and use the primer. Just follow LocTite's instructions.

    Re: SRAM Red / BBRight / S5

    Thanks for the replies. To again echo what has been said many times before, having you guys on the forums is a massive pull towards the brand. Back on the topic. So ( having read through the BBRight site .. ) I assume the S5 uses Pressfit30 bottom bracket by Sram but this is different from the from the standard Pressfit30 BB as BBRight uses a 79mm left hand side rather than BB30s 68mm. This difference means we can't use the Sram Red crank and therefore to use it natively we have to use the S900/975 etc. So the complete setup would be Sram Pressfit30 BB ( special 79mm version - why is still called '30' if its different from BB30 - thats confusing - anyway ), Adaptor by Enduro ( since the WheelsMFG adaptor is only for Direct Fit ) and SRAM Red GXP cranks. Hopefully my understanding is correct. Again, thanks.

    Re: SRAM Red / BBRight / S5

    Hi frent,

    Correct, the S5 uses the PressFit30 (46mm diameter inside the frame) not DirectFit (42mm diameter inside the frame).

    Correct, the S5 frame shell is 79mm wide, not 68mm. (68mm PressFit BBs work, the sleeve just doesn't meet inside).

    Correct, the SRAM S900 and S975 etc. have a 30mm axle (thus the "30" in the name), and require the PressFit30 BB.

    I think you also understand this part, but just to state it clearly: your existing SRAM Red crank (with 24mm GXP axle) will work in the S5 using the bottom bracket listed on BBright.net: Enduro P.N. BB 61806 LLB (same part as Cervelo P.N. BB-P-END-BBR-S).

    Bottom line: Use Enduro's BB (PN above) and your Red GXP cranks should fit perfectly in the S5.

    Hi Damon, Sorry to go on about Bbright but i'm just about to order an S5 to replace my S3 - well actually i might be hog and keep both! I'm a Campy nut and have Record and Super Record that i can fit - there is only one Campy cup listed whereas Campy list 2 types, one for Super Record and another for the rest - does the listed Bbright Campy adaptor fit all Campy UT cranks ? I'm assuming they will also require Locktighting in ?

    Re: SRAM Red / BBRight / S5

    Hi bigmac,

    No worries, I like to go on about BBright myself. ;-)

    The Campy BBright cups work for all UT cranks, including Super Record. In fact Jason, one of our Customer Service techs, has been riding Super Record cranks on his R5 all season.

    Yep, you'll want to LocTite them into the frame.

    Enjoy your new S5,

    Damon

    Damon,

    I just received a warranty replacement Sram PressFit30 BB for my faulty BB on my 2011 R3(same 79mm wide shell as the S5) My bike came with a Sram S900 crankset, unfortunately the BB Cervelo sent my LBS is the 68mm wide and not a 79/83mm wide like the one that was originally installed.

    If Cervelo installed a 79/83mm wide Sram PressFit30 BB, why are customers being sent the 68mm wide BB, which as you mentioned do not overlap or meet inside?

    Even if the 68mm wide BB cups work, you are still left with a gap inside the frame where the two cups don't meet.  This could potentially turn into more problems if water gets in there and ruins the bearings housed in the nylon cups. 

    Is this a Sram supply issue or is the parts department unaware that they are sending a non-matching part from what is originally installed, and  where can you find these 79/83mm wide PressFit 30 BBs for BBright frames?

    I've also seen that the specs shown on the website now show the R3 with a Sram S900 crankset, but an FSA BBright bottom bracket... Is this an availability or compatibility issue?  Seems to me that a Sram crankset should have a Sram/Truvativ bottom bracket, at least that's how my R3 came assembled.

    For reference here is a pic of how my BB cups were installed incorrectly, meaning one overlapping due to breakage, but if you look closely at the writing on the outside edge of the BB cup you can see where it reads: PRESSFIT 30 L (79/83 MM) and that is not what I received as a replacement from Cervelo. My bottom bracket went on to fail on the non-drive side, with the bearing running extremely rough by now.  In addition, another problem which I hope is being addressed is the potential absence of the clear spacers that go inside the wavy spring/washer.  That was another reason my BB failed, as it came with no spacers at all, and ultimately the side-to-side play made the problem worse and put the bearings under uneven load. 

    I hope by now all these issues have been resolved, but with more people buying S5s, BBright bottom brackets issues could turn into a very hot topic.

    Hi Hutch,

    First, please accept my apology for the toubles you've had with your R3 bottom bracket.

    Now I'll try to address each of your questions.

    1. You guessed it: you recieved a 68mm PressFit bottom bracket due to a supply issue. I agree a seal without a gap should be better. However there are two factors to also consider:
      • Water in your R3 frame exits quickly through the drain hole in the bottom. Cervelo drain holes are more than double the size of many other brands'. Our testing showed the typical drain hole is too small; water's surface tension prevents the water from passing through if the hole is too small.
      • Also, despite the non-contact inner seal, the 68mm PressFit bottom bracket still passed our endurance test (there's a desciption of the test protocol including two videos is in this blog post: http://www.cervelo.com/en_us/news-blog/engineering/article/ask-the-engineers-how-was-bbright-tested/2684/ ).
    2. Cervelos might ship with either SRAM or FSA bottom brackets. As you mentioned, this is a supply issue, not a compatibility issue. Both BBs are fully BBright compatible.
    3. Your pic is really good - it very clearly shows the improper assembly and the writing on the edge. The assembly error shows initial catch on the edge of the tube as the press fit was initiated, leading to a cut tube. Of course we're assembling more carefully now to prevent this error by controlling alignment as the cups first begin engaging the frame and each other. BTW, you probably guessed "L" on the edge simply means "Left" ("R" means "Right" on the other side). Of course 79/83MM describes the frame's bottom bracket shell width.
    4. We've revised the work instructions for our assembly technicians to include specific details about the clear plastic spacers. This requires more than just slap-it-together assembly, as each job needs to be checked at the time the crank is installed. The number of spacers varies depending on the stack up of all the components' tolerances. According to the crank makers' instructions, add enough spacers so the wave washer is compressed but not flat.

    Hutch, thanks for kindly calling these issues to our attention. I hope I've answered them well and that you're all set to begin enjoying your R3 again!

    Cheers,

    Damon

    Damon,

    Your reply is greatly appreciated, especially by adding some testing data that puts emphasis on the 68mm BB working just fine.  I'm in the process of buying the Loctite products necessary for installation and hopefully have the new BB installed soon.  Outside of this issue the bike has performed flawlessly.

    Thanks again,

    Hutch.

    Re: SRAM Red / BBRight / S5

    Damon - Hello, is there any word on whether the SRAM Red crank adapter will be made available any time soon?  I know the BBright website compatibility chart lists the part number we'll need, but as far as I can see that part is not available yet.  While I understand that this is a SRAM issue, I thought perhaps you fine folks at Cervelo might have heard something and perhaps could pass along the good (or bad) news.

    Thanks,

    Chris

    Hi Chris,

    I'm travelling so can't check expected availability. Can you contact Cervelo Customer Service?

    Hi Damon,

    I'll be curious as to what CCS has to say.  I just got off the phone with SRAM tech support and was told that at this time there is no adapter in the works and that only the S900 or S950 will work.  An email inquiry was sent to CSS this morning, so it will be interesting to hear what they have to say.

    Re: SRAM Red / BBRight / S5

    Hello Damon, I see that You know a lot about BBright. Well, I do have huge problems with Campa UT cranks. I have already glued them twice (Primer 7649 + Locite 609). A few kilometres of ride and the DS cup is traveling out of the frame. The Loctite is not able to keep it in place. I inspected the frame. To me, it is substandard. I already checked Cervelo BBright darwing. It says there is to be at least 13mm contact area for cups. Well, my frame has only like 8mm at 2 points, which led me to a conclusion that it is substandard. Will I be successfull in claiming the frameset? (If it was possible to add photo to the forum, I would attach it so You can see the BB interface) What is You opinion? Thank You.
