it should be from 95; size 18" - I guess

It's a size 19. He's measuring c-c instead of c-t. And it's a 1 1/8 steerer (the Velocity measures 1" because it fits inside it!)

I'm not sure I'm quite as sanguine about that dent as he is - the tube is only 0.4mm thick at that point. But I'm no expert.

You've forgotten more than I have ever known about Konas

Classic Kona brake lever dent in the top tube?

Looks about the same as mine... they both look to have a crease.
I did mine in 1995 and seeing as has not failed under my stupidity I would reckon that thing is pretty safe.

Mine for comparison - not the best picture as is usual for me

Behold! An expert.

I stand corrected.

max should be fillett brazed
Seriously though, that dents pretty big, and it looks like its had a hard life and earnt its keep. . .

Went for £183, which values the frame pretty close to zero. So maybe Professor eBay agrees with elite504, but it seems quite cheap to me for a dented Explosif.

PS all tubes prefer to be fillet-brazed, but Serotta TIG-welded the T-Max didn't they? The oval shape does give a strong weld anyway, and it's a heat-treated tubeset, so I would have thought it was strong enough.

The only place where these frames tend to fail is the rear dropout, and there it is the actual dropout - solid steel - that snaps, not the tube, not the join.
