is there any hope for this little peg?

[jr59]

I would bet that Frank the Welder could fix it. But to each their own

I am curious as to how this would cause a catastrophic failure?

[huck*this]

Fork not properly pre-loaded?

I'm digging the idea of a designated trainer bike.

Looks like AC did a farewell in almost the same scheme.

I would certainly ask him if I had a desire to keep it on the road.

-17 here. I think he was pretty old school in regard to geometry, so it's no surprise to me that it matches and rides best when it matches what a quill stem rides. I ride in the drops about 50% of the time though.

I don't see it either. At least not an imminent failure. I do like the idea of turning it into a trainer bike though.

Stop drilling a crack is a pointless exercise unless you can really pinpoint the end of the crack. Most people miss the end of the crack and they have removed material that actually slows crack growth. There are only a very few applications where it does anything useful. Aircraft sheet metal mechanics do it sometimes, but certainly not in an application like this. And after it is stop drilled, the likelihood is that it will be patched or otherwise repaired.
Not sure why this always comes up in bike forums by people who have no expertise. I guess it's because it's not their teeth.

Could you turn a steel ring that would be a press fit around the top of the headtube? If you matched the paint to the headtube, it would be almost invisible under the top cup of the headset. Even painting it black would be OK.

It seems that a repair of that type would prevent any further expansion of the crack, since it would be held in compression.

It would be a shame to retire this frame, or to relegate it to trainer duty.

I have a metal lathe, want to sell the bike?

Not a farewell - that bike is a decade old.

i'd ride it.

If the crack extends into the weld of the top tube(inside), and the top tube separates from the head tube..which might lead to the front end coming off..maybe some 'pal' would do a hose clamp but screaming down the hill, into that tight right hander...I wouldn't do it. Not the same but you get the idea..'ingenuity'...funny, hopefully the dentist is ingenious as well..

[soulspinner]

Ya...…... no.

[Big Dan]

I wouldn't mess with it.

[chiasticon]

didn't see it mentioned but this is on eBay right now. so I don't think Angry is looking to have one of his bikes repaired so much as either considering buying this, or just curious what people think of the idea of repairing it. mentioning because this would factor into the decision, for me. if it's a well-loved bike I've spent years on, I'd be equally likely to repair it versus hang it up as art/memorabilia. would I buy it to repair it? no. if it were given to me, would I repair it? yes.

I have a lemond 853 steel frame that cracked right there at the same spot as well as down by the bottom bracket... a non bike friend of mine who knows how to weld (but who knows welding very well and is a real master at it...it cost me a case of beer) got it fine...been riding it for about 8 years since and it is more than solid...guess it is your call...personally, I would go there. Not sure I would if I lived in the mountains and going down 90 kph descents but I live in the flatlands...steel can be welded I think or that is my experience and I think alot of folks over react as to its properties and safety... but I am sure others will pitch in and prolly know better.

Updated eBay post says "my friend at the shop found a second crack in the head tube"…just sayin'
