95 Kona Explosif Bottle Cage Mount Repair
Hi All!
Just picked up this Explosif and it has had a cage mount ripped out. Can/should this be repaired?
Thanks for any assistance!

Yes, steel, as DorkDisk mentioned. The upper mount is tight...

When did any bike makers decide it would be a good idea to use a rivet-style boss in thin, butted cr-mo tubing?
Someone added such bosses to my Pro-Tour's downtube, adding a second cage and even an extra boss to lower the stock cage mounting a couple of inches.
It hasn't failed, yet.
My Bianchi Nuovo racing is also the victim of someone with a drill, has holes drilled in the butted seat tube and the actual bosses glued on with J-B Weld (one of which broke loose).
Lucky I guess that I'm light enough to ride these without breaking anything for a while. Of course I got the Bianchi cheap and did rescue the Pro-Tour from the trash.

If the cracks don't go too far, you might be able to save the frame by brazing on some of those star shaped bottle reinforcements. Like these:
If it were my frame, I would whip out the torch and have it sorted in no time. I don't know whether you could pay someone to do this, or if they'd all say the tube needs to be replaced.

Explosif is what it looks like happened to it! Hope you find a fix.

Nope, lots of good parts on it though, wheels, all XT parts, Marzcocci XCR shock, which needs a rebuild. I might still ride it after the shock rebuild.

I would not expect our local frame builder to charge you more than $100 max for both bosses and maybe much less but the paint damage would be a serious problem and make it unreasonable. The cracks I see are serious stress risers, if you are a risk taker I would strongly encourage you to stop drill the ends of those cracks and avoid long, fast declines.
