I can not be the only one. Hell, I have three with broken.

This was less a chance to show off, and more on how/who to fix

If not too close to the chainstay, file a "V" into the crack to clean out any corrosion, then TIG across the crack and file to suite, cosmetically.

That's exactly how Bernie Mikkelsen repaired one (a shorty Campy DO cracked in this same spot). He told me this was a common point of failure for those DOs and as a result he did a lot of these repairs.
His wasn't "pretty" when done but he said: if you want better looks then have at it with files for as long as you like, but this weld is going to work.

One and only frame I have had a breakage (touch wood ) on .
Bought it to ride while visiting relatives in Australia .
Went bang five days later .
Stripped it , kept the components and binned the frame in disgust !

I think I saw in another thread that you are in Santa Cruz. If so, you may want to take it to Dale Saso in San Jose to look at/repair. A few of us in the South Bay/Peninsula have used him for various repairs. https://sasobike.com

Rear hangar cracked—first had it all welded and then fitted Surly horizontal dropouts

Marked the shape of the inset and calculated depth required

All trimmed

Locked in—drilled mounting hole and bolted in (no pics of that, I guess)

Works well!

This one came and went to the Atelier recently. Riv and Dale Rambouillet. Happens to the best of 'em. Customer called Riv, Dale sent out a new dropout they had.

When you don't have a TIG setup, but do have a torch, all repairs look like a brazing solution.

So I traded a six-pack of New Glarus Oktoberfest for the frameset in post # 9. Having neither means nor skill for such a repair, I contacted Andy @ Yellow Jersey, who would replace the dropout rather than repair it. Fair price, but more than I'm interested in spending. So I've stripped it of the stem, Suntour 7-speed Accushift shifters and cartridge BB, and for anyone looking to hone their skills on such a repair, it's yours for the cost of the ride.

I have a couple, both bought as frames with the damage disclosed:

Motobécane Team Champion 1984 (the last year, I think -- more photos here)

Previous owner got it new as a teen, had ridden it enthusiastically for 30-some years, and then the drive-side dropout cracked. Sold to me (via CraigsList) for $30.
I had my trusted bike shop fix it with a TIG repair




The other is a 1950s F.W. Evans (English) frame (more photos here) bought as a bargain mark-down from Hilary Stone, because of the damaged dropout I suppose. Dropout seatstay tab broken through just below the stay end, and repaired by brazing before Mr Stone came by it.


Personally, I'd never trust that one as-is. The stay is pencil-thin (which I really like). I looked for years for a NOS matching dropout -- have a Jeunet frame in not-great cosmetic shape with the same ones, but otherwise in fine condition, that I got cheap, but can't bring myself to sacrifice it, even to fix up a more "valuable" small-volume builder frame. Eventually, I found an eBay auction for another Jeunet frame in 'beater' condition that nobody had bid on in a few cycles, so I wrote the seller and offered to buy just the rear dropouts and a few other bits for a reasonable price -- advantage to him was a sale, with no frame shipping cost. So now I have the raw materials, and just need to screw up my courage to ask gugie whether he'd take this on, plus a little fork crown seat work (means cross-continent shipping 2x), or get in touch with my local trusted bike shop, which closed their Manhattan shop pre-pandemic because they had to vacate after the building next door was condemned for structural instability reasons. They have another shop across the Hudson in Union City, NJ, but easily accessible by bus from Port Authority.

I put this off for quite awhile, and then more because for the last year I'd been facing open-heart surgery; if I didn't survive or survived with debilitating morbidity, what was the point? Now the surgery's done, I'm still here and haven't had a stroke yet. Still gonna wait out the recovery period before committing to anything even as trivial as a broken dropout.

Why no forks in here yet, you ask? Here you go, dropouts sheared clean off. Not caused by impact as far as I can tell, as the fork is straight, more like dropout spreading/straightening, who knows.

I will get it repaired at some point because this type of fork rake is becoming very hard to find nowadays. In the stash it goes.

I suspect the majority of real job healthcare broken from people using the wrong size axle and either spreading or squeezing the space. I also suspect the drive side is the one that always takes the brunt from the added torque

I suspect it’s probably 10 to 1 rear versus fork..

And going through the photos in this thread, it's almost 100% breakage ahead of the dropout slot right before the chainstay, sometimes through the whole chainstay tab, sometimes on the lower web below an opening in the dropout (connected to the upper flange of the dropout opening). Of course, many of these bikes have the chainstay flattened ahead of the droput for additional cogset clearance.

Can't figure out what healthcare has to do with it, though my doctor brothers might agree about healthcare being broken (not me; I think doctoring is broken).

It reminds me of that line from the movie, fast Times at Ridgemont high.

After he wrecks a car, spicolli says, “ my uncle is a TV repair man. He can fix anything“

I didn’t do anything to the frame other than cut it up for the recycle bin. Keeping the branded tubes to maybe make a wind chime

Sir, a question if you will. Was the crack at all related to the position that the two pieces wanted to be in, post break? Such as, internal stress wanting to pull apart against the connection, thereby leading to the break? Just looks sort of unnatural (to my untrained eyes), where each piece wanted to settle. Curious!

This is the way they were when I acquired these frames.


Norco Monterey 1985. Someone tried to repair, not me.


Miyata built in the 1970s.

I had a frame maker replace the broken dropouts.

Could have been repaired with a new seatstay, chaincstay, and dropout - question is whether anyone would be willing to bother. Many seem to be enamored with EM frames, so you never know...
