Carbon Fiber Bottom Bracket Issue on Scott CR1 Team

I have an issue with my Scott CR1 Team which I would appreciate all your feedback on.

I bought the bike used in September 2008. I believe it is either a 2006 or 2007 model. It was, and still is, an immaculate bike. Before buying this bike I had been riding a late 80's vintage aluminum Cannondale with Suntour index shifting components. So, a carbon fiber bike with Dura Ace components was a quantum leap for me. Shortly after buying it I had an accident (not bike related) that kept me off the bike for the entire 2009 summer season. So, I have only put about 1200 miles on it, most of them on the trainer. Recently the bottom bracket started creaking. Thinking it just needed some maintenance, I brought it to my local mechanic. To make a long story short, he determined the issue had something to do with the frame. He theorized that the aluminum sleeve inside the carbon fiber shell was loose inside the bottom bracket. But he didn't know exactly how the sleeve was bonded to the carbon fiber. And, at any rate, he had no way to fix it.

I called Scott to see if they could offer any suggestions. I had to call three times before finally speaking with somebody. (I left voice mails the first two times. The calls were never returned.) When I did finally connect with them they confirmed my mechanic's theory was exactly right, and it was a known issue with these bikes. But, because I was not the original owner, there was nothing they could do to help me. At one point, they suggested that the cause could be related to somebody over tightening the bottom bracket. But, given that they knew this was a issue, I am a little bit skeptical that overzealous mechanics were the sole reason for the issue.

Scott suggested Calfee could repair the bike by removing the original sleeve and inserting a new one. I did contact them and they confirmed they could fix it. It will end up costing about $400 for the sleeve replacement, repainting, and shipping.

I have a few questions.

> Should I be upset about this? I've tried searching the forum for others having similar issues. I couldn't find anything. Is this just bad luck on my part? Should I chalk this up to carbon fiber? I did find lots of debates on the pros and cons of this material. I don't think this would have happened on any metal frame as there would not be a sleeve.

> Could I have done anything to cause this? I've weighed in as much as 260 pounds at times when riding. So, I'm very heavy by cycling standards. But, I wouldn't expect this to cause this type of issue.

> Does anybody have any experience with this sort of fix? I've read nothing but good things about Calfee. So, I feel confident in them. But it would help to hear from somebody who had this same fix done.

Try talking to the original owner and see if he can get you warantee help. At 260 you are really pushing the envelope on a light weight carbon bike.
I have friends that have had issues like yours with Trek 5200's (different orarges) and Trek made them good for the original owners.

Scott is not going to do anything for you. They have no reason to help you out being that your money didn't go to them. The fact that it is a known issue to Scott makes it suck even worse because it sounds like its something that they would take care of without much of an issue if you were the original owner.

Its the nature of the beast. High tech components can lead to expensive problems. Scott's engineers may not have done all their homework when they designed their BB sleeve but things like these happen from time to time in all industries when dealing with cutting edge products.

Your weight doesn't help but it seems that according to Scott, it was a known issue. Your size may have accelerated the problem but sooner or later it may have failed. I ride a Tarmac Pro SL and weigh in at about 245 but ride really light. If you're going to ride a carbon bike intended for racing you need to be lighter on the bike than most other bikes. I don't know your riding style but if you typically do not raise your butt off the seat a bit or loosen your grip when things gets really rough you'll beat the bike to death over time.

Talk to the original owner and see if they can help out. If they have their original receipt or a copy of it you may be able to take care of things. If not Calfee will get things going for you.

Before you have anything repaired, make sure you have properly identified the source of the creak. These types of creaks can actually be related to a number of other areas on the bike such as: rear skewer, handlebars, stem, seat post, seat, even seat bag or tail lamp. Double check all of these items before making an expensive repair.

While I did have a Trek OCLV frame with bb shell/bonding issues, my situation was different. I was the original owner even though later on Trek invited me to consider my lifetime warranty no longer valid after a chainstay failure (on a frame replaced over the original issue). I also was capable of determining the cause of the problem, rather than guessing at a sound and taking it to a shop (you ever hear things in your car your auto mechanic can translate?). You bought used, caveat emptor for the most part. Why would you be upset over a used frame that you weren't the original owner/warranty holder of? Why are you buying weight weenie bikes used instead of dieting or are you just a large/tall kinda rider?

Magnuson–Moss Warranty Act

Here's something for food for thought. I believe this covers any manufacture's warranty no matter how they may write the terms. In other words, any warranty covers the product item, not the purchaser or goes with the product. Contact the Scott company with the attachment. Suggest that it would be in their best interest to settle the known problem, for public relations and most of all, DEALING WITH GOVERNMENTAL Bureaucracy, which will consume more man hours then what the problem is worth. Next, if they ignore the issue, don't threaten retribution, CONTACT the FTC!!!!

The Magnuson-Moss Act contains many definitions:

* A "consumer" is a buyer of consumer goods for personal use. A buyer of consumer products for resale is not a consumer.
* A "supplier" is any person engaged in the business of making a consumer product directly or indirectly available to consumers.
* A "warrantor" is any supplier or other person who gives or offers a written warranty or who has some obligation under an implied warranty.
* A "consumer product" is generally any tangible personal property for sale and that is normally used for personal, family, or household purposes. It is important to note that the determination whether a good is a consumer product requires a factual finding, on a case-by-case basis. Najran Co. for General Contracting and Trading v. Fleetwood Enterprises, Inc., 659 F. Supp. 1081 (S.D. Ga. 1986).
* A "written warranty" (also called an express warranty) is any written promise made in connection with the sale of a consumer product by a supplier to a consumer that relates to the material and/or workmanship and that affirms that the product is defect-free or will meet a certain standard of performance over a specified time.
* An "implied warranty" is defined in state law. The Magnuson-Moss Act simply provides limitations on disclaimers and provides a remedy for their violation.
* Designations:
o A "full warranty" is one that meets the federal minimum standards for a warranty. Such warranties must be "conspicuously designated" as full warranties. If each of the following five statements is true about your warranty's terms and conditions, it is a "full" warranty:
+ You do not limit the duration of implied warranties.
+ You provide warranty service to anyone who owns the product during the warranty period; that is, you do not limit coverage to first purchasers.
+ You provide warranty service free of charge, including such costs as returning the product or removing and reinstalling the product when necessary.
+ You provide, at the consumer's choice, either a replacement or a full refund if, after a reasonable number of tries, you are unable to repair the product.
+ You do not require consumers to perform any duty as a precondition for receiving service, except notifying you that service is needed, unless you can demonstrate that the duty is reasonable.
o A "limited warranty" is one that does not meet the federal minimums. Such warranties must be "conspicuously designated" as limited warranties.
* A "multiple warranty" is part full and part limited.
* A "service contract" is different from a warranty because service contracts do not affirm the quality or workmanship of a consumer product. A service contract is a written instrument in which a supplier agrees to perform, over a fixed period of time or for a specified duration, services relating to the maintenance or repair, or both, of a consumer product. Agreements that meet the statutory definition of service contracts, but are sold and regulated under state law as contracts of insurance, do not come under the Act's provisions

Hope this helps,

Just for anyone with this problem....

My 2007 Scott CR1 Pro had the same issue. The Alumnium bottom bracket sleeve had become unbounded from the frame.

Out of warranty but Scott gave me a repairer details.

HQ Fibre Products
Vale Farm Workshop
Blofield Road
NR13 4AJ
01603 713972

The cost of fitting a new sleeve including mailing it back to me is £111

Pretty reasonable IMO.

They also rushed the job through so I could have back to me for a crit (in less than a weeks time).
