I just broke the frame of my Trek 4300. The crack is on the chainstay about 3 inches from where the seat tube and chainstay meet. The break is completely through the frame. I can't believe this..I was just riding on the bike path (paved), went over a bump where a tree root has lifted the trail up a few inches (it was less of a "jump" then going down off a road curb!!) and all of the sudden I realized my rear was wobbling. To my knowledge there was no crack prior to this incident.
Anybody ever dealt with Trek in a similar situation? I couldn't find my manual but I think the bike is only covered under warranty for a year. I've had mine about 2 years. I haven't called the bike shop yet, but I doubt if they'll be able/willing to do much.
I live in north wales (thats the little country next to england for all you yanks that didn't know) in a little village called Northop.
A Trek jack with sherman fireflys, shimano hone cranks, hope hubs, dmr rims, easton bars and crappy shimano cable discs.
i have had the exact same happen to me only a week ago! my trek bruiser 05 got a crack in the driveside chainstay 3 inches behind the bb shell. my bike is 19 months old. i think you'l find that all trek frames are warranted for life. when i sent my bruiser back i got a brand spanking new jack 3 frame!! id say return the bike back to wherever you bought it and get them to send it to trek, i reckon youl get a new frame out of it...
I don't know about the current warranty on Treks, but a few years ago a friend of mine broke his Trek mtb frame and they replaced it under warranty. At the time, his bike was several years old, but I believe it had a lifetime frame warranty. The only way to know about yours is to check with your Trek dealer. Good luck-
I'm very pleased with both the bike shop and Trek. Trek gave me new components (brakes, deraillers, shifters). I had thought that they'd just give me a new frame and then I'd put all the orginal components back on. I had just replaced the crank arms, bottom bracket, chain, and cassette so I didn't kept those. I wish now that I hadn't replaced those components last month, I coulda saved about $200.
