Fat fish

Sorry I was naughty, but that's a good one. Year ago I have sent the frameset for the corrosion via the bike shop I bought the frame and I thought they declined it,because Specialized and the bike shop had some issue with each other and that is the reason I took a day of from work to take itself to Stellenbosch. I honestly forgot to tell them about the squeak of the frameset and it did only cross my mind now that we talking about the after effects of the corrosion taking place on both side of the seat stay by the lugs. The frame still made a noise and all time I was thinking the sound came from the crank or from the set post.

Guys thank for opinions, but I need your expertise once again.I am sitting with another problem with the same frame. I total forgot to mention it as corrosion took over my brains. About six months ago the frame start squeaking and was in and out the bike shop to have it fix. I have send it to Olympic for a major service and the confirm that my BB and crankset is fine and everything else was fine. Two weeks on the bike the frame started squeaking again and it only happens when I am climbing. I have sent it to a specialized mechanic and he took the whole crank and BB apart and still commenting that I have a very good ceramic bearing and should not have any problems, but a week later it happen again. By that time I was training for the ARGUS and could not afford letting the bike stand by the bike shop.I got another mechanic to look at my crank area and he greased it up for the Argus. I don't know if the squeaking is coming from the crank or from the frame itself. The day I took the bike to Specialized in Stellenbosch for the corrosion/paint problem, I completely forgot to mention it to them. What do you think can be the problem. I will definitely be taking it back to them to have it check out and give me another report. Will be look forward to see what the assessment report will be telling me this time. Look for your opinion again. Could it be that the corroded area is making the noise, as I had the BB and crankset check out on numerous occasion. I actual got frustrated as a cycling buddy is riding an old Cannondale aluminum frame and no noise from his bike.

This quote taken from a international bike forum The problem the guy had with aluminum was due to galvanic corrosion and poor electrical insulation between the carbon and aluminum, not because the carbon absorbed water. Water was a factor, but would have been just on the outside surface. So, that's dumb.

The material use in the manufacturing of the frame (cardon and aluminum Lugs) is the cause of the galvanic corrosion and it was not properly insulated from each other. Titanium lugs should've been used and no corrosion would of taken place. Both sides is infected and that is the reason questioning. Usually when there is galvanic corrosion between Al and a carbon composite, any whitish powder is aluminum oxide from the oxidation of the Al component. Where it shows up will probably be variable, but it will originate from the Al part. Point is, it may not show up under the paint bubble, if in fact it's a result of galvanic corrosion. On the composite side paint adhesion can be lost to something like hydrogen evolution as the reduction compliment to the oxidation of the Al part.

Sorry. System was slow.

I am learning a lot and with this news it becomes very much clear they should actual replace the frame within the frame warranty and not under the paint warranty as they insinuaing. I think they will be ignoring my finding and stick to there original decision. I'll still loosing out, as big brand like Specialized is not going to admit that they were wrong. Specialized fanatics and I was one of them, this is enough proof that my frame should have been replaced and not use a petty excuse of corrosion and not providing me with an explanation of what could of caused it. Is see myself as harden cyclist and with that I have always maintain and look after my equipment and making sure it gets it's regular service. Thank you for the hubber that stood with me and providing with all the informative information and for the hubber that loader the report for me, a special thanks you. But know I am looking for a frame. Anyone willing to donate one or start running and hopefully I will not have issue of running shoes corroding.

Have any one heard of galvanic corrosion that only take place between carbon and aluminium. Some interesting information Carbon, corrodes, you get galvanic corrosion setting up wherever there are metal inserts on the frame and the thing becomes one huge great. Carbon corrodes extremely slow. I'd be dust before it happens. However since carbon is more cathodic, it can cause more anodic metals such as aluminum to corrode faster

Interest article I find on the web. I used to work in a bike shop that was a specialized dealer (in fact it was owned by the British Specialized importers). We had a lot of trouble with the early Allez epic carbon frames, as the bond between the lugs and the tubing persistently failed. It transpired that the adhesive used was basically water soluble, which became weak after immersion. This fault was obviously kept rather quiet at the time.

Is this part of the paint warranty or structure. I will think that corrosion will be under the frame warranty as the infected area is on the frame which cause the paint to bubble.

So I take it that you one of the people that look at there bike everyday. Atleast my car does not take that quick to corrode and it's metal where as the bike is carbon.

Let me put this whole story in perspective. I purchased this frame on the 16.11.2012 ( Less than 3 and half years old) just before DC and I only notice the very vey very small bump just more than year and half on the one side after I purchase the frame. Not knowing about corrosion can settle in so quickly, as I did not have any issue with my previous frame. The bike got regurlary service at the bike shop and they also did not notice the corrosion. Before the 2015 Argus, I was to late send the bike away for the service and decided to clean it myself and it was only then that I notice the very very very very small bump is growing . I then took it to the bike shop where I bought the frame and they send it of to Specialized to have it checked out. The report confirmed it's corrosion and that the paint warranty is only 2 years. I did not understand it , as the paint was still on the frame and the bubbles is forming under the paint. By that time the bike shop and Specialized had some issues and then decided to take the frame myself, as a owner of a Specialized product, which I specially took of from work and drove to Stellenbosch to the head office and I was basically provided with the same report, but the only difference is that the infected arear grown big and the other side is also infected, which was not on the previous report. I cannot understand how it can corrode like that, as my bike and my wife's bike is standing in the same room and there is nothing wrong with her bike.

did you get the report

No Problem. I'll appreciate it if your can load it for me. I think from the pics and the report i can maybe get everyone's honors opinion.

I think that will change my frames name from Specialized Tarmac Pro to Corrosion Tarmac Pro.

nobody interested in seeing the report.
