Trek 1400 with Cracked Frame
 

Not sure the year on this one. 18 speed. Shimano 105 Brakes, derailleurs, Shimano Ultegra shifter/brake levers. Front wheel Mavic Open 4, front tire Maxxis RC-Fuse 23mm, rear wheel Giant S-R2, rear tire Continental 25mm.
There is a crack in the frame at the top of the seat tube, see photo. Anyone know how this affects value?
Was thinking $180

Located in Denver CO

Humongous crack across the side of the seat tube. Some here will say it can be welded, others will say don't bother, frame is toast. I'm in the latter category. Worth only whatever parts are on there.

Probably cost as much to fix as to buy one in good condition. IMHO, that's a parts donor bike only.

Cheers

Thanks!

1991 I have one; ouch!

On his one no the frame is toast To bad since these frames are about the toughest production frames ever made make me think how the hell did the upper seat lug get broke.

The frame is worthless, the value of the components depends on how patient you might be selling them. Could be a lengthy project

You can't sell it but you can give the frame away to a cyclist that has access to aluminum welding equipment and the skill to weld that crack close. Which would keep the otherwise good bike on the road,..........instead of being turned into soda pop cans.......

I had a cracked Trek Aluminum frame like this years ago, I inquired around and consensus was that it couldn't be welded reliably since the frame was heat treated.

Best guess would be a seat post inserted to little. I have seen lots of stretched lugs and a couple of broken ones, over the years.

If the owner is the original owner, Trek might replace it on warranty.

Thanks everyone. I purchased it for $130. Since the crack doesn't affect functionality, I'll ride it around for a while until I find time to sell the components or look more into welding.

Dunno where you get that idea. This looks like a, uhhmm.... potentially parenthood-threatening incident waiting to happen, IMHO.

Looks like the crack extends all the way to the non-drive-side seatstay. The seat tube could collapse with added stress, i.e., riding. I'll second what madpogue said. Riding in this condition is not recommended, but hey, do whatever you want, and let us know what happens.

:foo:

UH. :eek:

This very possible that at some point a previous owner put the seat up to high then just a little too much tightening on the seat stay bolt is a good way to break a hardened alloy frame.
