My LBS discovered a nice little surprise when tuning up my 2008 GT Marathon Team this morning: the rear brake cable literally rubbed straight through the carbon (see pictures). That was a catastrophic failure waiting to happen -- good thing they caught it. Bike is a little over a year old. :madman: Looks like I'll be riding my '96 Avalanche until this gets resolved.

Let me know how it gets resolved. Shortly after I picked up my bike (March 08) I realized that the rear swing arm was not centered over the seat stay. I took it back to the shop and asked them to contact GT and help resolve the issue before it got to the point where the carbon wears through and they blew me off (a bunch of "we aren't aware of the problem" "we don't see this being an issue") So I did the best to protect the frame where the cable is routed but it still isn't correct (the swing arm should be centered over the seat stay and the cable shoudn't be pinched on left side) Can't wait to here how your shop resolves it, hopefully it's not Performance or you may get the same BS.

Do you also have a marathon? I'm willing to bet my bike suffered the same problem. How else would a cable eat through 1/8" of carbon?

I picked mine up in March 2008 too... and... of course through Performance :rolleyes: . I've been a long time GT rider and they had the bike I wanted. I'm having my local bike shop give GT a call tomorrow, but if it has to go through Performance, well, then we'll have one big company dealing with another big company (Pacific/Dorel). I don't think either really has the end customer in mind, especially when such a big ticket item is at stake (these frames retail for $2000).

I'll let you know what I hear back.

Please do.

I should hear back from GT tomorrow.

Also worth noting is that the bottom pivot shell (part of the frame) has become "ovalized". It's no longer circular. That shouldn't happen either.

Ok, The bottom shot shows the rear swing arm and how offset it is to the one side, you can see the pinching brake cable on the left side (lots of room on the right)
The top shot I pulled the brake cable out of the way to show the damge to the frame, not as severe as yours but definately through the paint and several layers of carbon.
Keep me updated.
The bike has been great otherwise.

That certainly explains it -- there is no other way that the cable could've eaten through the frame so quickly. Did your bike ship this way? Has it ever been disassembled? I'll be hearing back in just a couple days and will let you know.

Just picked up my bike from the shop.

GT warrantied the frame. I was surprised at how quick and hassle free the whole process was. The etching quality isn't as nice and the matte carbon has a different feel, but I'm glad it's fixed. Probably just a different production run.

jmsracer -- you're going to have the same issue in time. My shop decided not to route the cables between the main and rear triangles (see the second picture). Even rebuilt, the seat tube is NOT centered and the left side would still pinch the rear brake cable.
