If your only adding welds to the surface it wouldn't really need to be heat treated, it's not like the weld would actually be holding any tubes together or anything.

No but about 40% of the head tube would, to a varrying degree, be in the heat affected zone making it a lot more brittle than the heat treated alloy.    The HAZ would probably also go as far as the underside of the headtube/downtube weld which is the highest stress area on your frame. 

Press a deep cup in or buy a new frame, or as Orge suggests, get a professional reapir done if its cost effective.

Have you spoken to Specialized? They are pretty dam good with warranty stuff, so I'd imagine they'd want to help out with a replacement front end at cost or something if its crash damage/user error.

Can I just say, thanks for all the replies, but I really dont fancy a bodge job (ie fitting a deepcup headset).

I cant be arsed with having the worry of the headtubve cracking, when Im physcing myself up to do a new big drop (or whatever), would rather just get a new frame.

Plus, a mate has said he'll pay £250 for this (inc shock), so yeah, score Smiley

Think so, go for it! Maybe contact the previous owner and find out which shop he got it from, may be able to help.

Its not a deep cup headset like a chris king. The reset racing headset is bigger (like 1" and 1/7th or something) and you machine your headtube to fit. Very different from simply using a bigger contact area like the chris king...

Nope, just take it to your local engineering shop and tell them the diameter you need, i'm guessing on around £10...

Yes because everyone s privalaged to have one of those. I wouldnt bother, by the time parts are bought and fitted you still have an old damaged frame.

If his mates gonna pay £250 then thats a big helping hand to a replacement frame

just a note to any sx or enduro rider reading this, the picture with the snapped stay is common problem with early sx or enduros there is a warranty replacement for the chainstay if this happens and will be covered for a free replacement. to check if you have a good or bad stay, check where the breather hole is on the stay if you look at the pic its on the inside of the stay - near the tyre - on the replacement ones its on the outside on the flat part close to the pivot. I have replaced a few of these now and they have warrantied them all, however it is unlikely that they have the right colour stay. all the ones i've fitted were black or brown. Smiley
