I almost pulled the trigger but then I noticed the part about the cracks on the seat tube. Although I believe that bidders who don't read before they bid deserve usually deserve whatever they get, it seems to me that part of the description should be more conspicuous (bolded, larger, set apart etc.).

Still, would be a nice pickup for somebody who can weld or get the repairs done cheaply.

You won't cause a crack like that by using a correct-size shim, so I don't know what he's talking about. It looks too dodgy to ask money for it - he should give it away to an RM collector.

oh, by the way, it's unrideable

He goes on and on about his experience with the bike, and sticks one sentence in his wall of words, mentioning the crack.

I saw another RM e-stay cracked in this same way...believe it was a frame on ebay less than a year ago.

Seller should keep it since he's been through so much with it.
I would.

How did he buy and ride a 1991 bike in 1989 :roll:


Red stickers, pearlised colour that this frame is 1991
white stickers and more importantly 'raw polished' alu is 1990

The reason I called it dodgy rather than unusable is that the crack isn't the result of riding forces.

A crack caused by riding forces is clearly going to be made worse by further riding, and if that was the case here the frame would soon break. But if this crack is caused by over-clamping and that cause is removed, I don't see why it should necessarily deteriorate/break.

Based on what I've read, you could drill a hole in the end of the crack and that would deter it from elongating. If you then removed all of the welded-on clamp, cut out the crack into a clean slot, fitted a very tight post well into the frame and used a double external clamp to secure it, might that not last for a while?

And it wouldn't cost you much, so if you got the frame for nothing it could be a reasonable gamble, better than throwing it away. That was my logic anyway, but I'd be grateful to be put right by someone who knows better.

The frame is 7000 series like my Stratos so it should take re-welding without any trouble – might need to get the seat tube reamed if the weld penetrates all the way through, but I'd have thought it's worth a few quid to try.

Not a UK repair though as the cost of shipping on this one would make it a pricy frame even if it was repaired successfully. One for our states-side friends I think.
