UH-OH, this can't be good -- any advicemaximum15
Feb 14, 2002 9:57 AM
Just found that the paint is cracked (missing) on the inside of the rear brake cable guide on my top tube (Trek 2300, '99 model). This means that the aluminum is corroded (Florida) and there is some galvanic corrosion between the aluminum and the brake cable ferrule where it fits into the cable guide. Of course, these two are now basically welded together. The paint is also beginning to peel from the cable guide and corrosion is visible underneath. Any advice or thoughts would be appreciated, flames will be ignored.

I would look at Trek's web site. I recall at on point you could e-mail Trek for technical advice. If it's still available, that's what I would try.

I saw the same thing with my '99 a few months ago but decided to ignore it since it doesn't affect the frame's structural integrity yet. This frame will become a beater rain bike so I'm not too concerned. Maybe mine isn't as bad as what you described though.

If I were to repair it, I'd grind out the area slightly. apply some aircraft zinc chromate primer. Repaint the area with model or automotive touch up paint. For smaller problems, just use CorrosionX a few times a year. Nothing else works as well and costs so little.

I' noticed a similair thing on my Trek 1400 over a year ago. There's what looks like corrosion beneath the paintwork in a couple of patches, plus a more serious looking patch, which I initially took for a crack on the seat tube just above the bottom bracket. A Trek rep claimed it's just where the bonding has moved slightly beneath the paint, and is only superficial damage. Not sure if this is entirely true, but I've been riding the bike regardless. It's now a rain bike so i'm not too worried in any case, but its had a lot of miles put on it since noticing the problem, so I don't think it is anything to worry about just yet.

Most likely cause is that they didn't use the correct primer (if any) or apply it correctly. Technically they should be using something like alodine (sp?) underneath like they do on airplanes. Obviously there is a defect in materials and workmanship However, Trek only warranties finishes for a year and will use this to get out of taking any responsibility. They pulled a variation of this stunt on me when I had a problem with my nude OCLV and said that I should sweat on my bike. I was so mad at them I said F'em and sold the bike and relate this experience whenever the opprotunity comes up. I hate to break it to you but unless you can sweet talk them they will be bastards on this issue - they have lots of experience and practice. Seems like it would be easier in the long run if they just did things right. A salty coastal environment just makes things worse.

I had a '99 2300 from a sponsor at the time. Not to turn into a Trek-bash, because I still have a lot of respect for the affordable, quality bikes Trek builds for the racing masses, and they've done a stellar job wtih the USPS team bikes. Unfortunately I think the frame I got was one of their "seconds", because it was the shoddiest workmanship I've ever seen. My 4-year old nephew makes prettier welds on mud pies, and the seat tube was installed crooked so the clamp slot was cocked off about 3 degrees to the left. I had similar troubles with the paint chipping/corrosion (the BB shell was all blistered & disgusting looking after 6 months). I also don't understand how Trek can build an uber-stiff Al frame that rides like a friggin jackhammer yet still has limp noodles for chainstay / BB lugs.

My solution to the matter was to Ebay the Trek and buy a couple Colnagos at cost from the owner of a bike shop I used to work for.

Do you really expect Trek to repair a little patch of surface corrosion on a 3 year old bike for free???
Try to warranty itspookyload

I too live in Florida, and have built two Cannondale caad4 framesets for the same customer for corrosion problems. I don't want to guess what Trek has to say, but Cannodales fear lies in unknown fram reliability due to corrosion. They would rather warranty the frame than risk possible litigation for a crash becuase they wouldn't replace it. The sick part is this guy never cleans his bike, and it is always covered in sweat from top to bottom. So give it a shot, and you might mention the reliability/liability issue.
Take it to a dealerBen R

Trek is pretty good to their customers - I don't care whether it is due to liability concerns or from the goodness of their hearts. I got an OCLV replacement for my 1996 2300 that came unglued at the bottom bracket. That was a special case though since my frame design was no longer made and I didn't want aluminum. Anyhow, I've heard that they have promptly replaced other frames as well, all with a wide variety of problems. Take it to a dealer BEFORE you try any handiwork at home.

I'll take it to a dealer (or two) and see what they say. If that fails, then I just fix it myself. I don't see the problem affecting frame integrity yet, but if it is allowed to continue, it could eventually mean trouble. Sad to hear so many people have had similar problems with Trek frames.
