i think theres a simple solution to yur problem. Go see your local engineering place and get them to weld it back together and heat treat. Or even better get them to weld on a new regular size headtube.
Problem solved
that would ruin it lol
MGP is heat treated, the reason it breaks is cause of too much heat when welded.
From what Billie has told me they come with a one year warranty, shaun has already got a new deck free of charge.
The new mgp nitro will have a fully forged headtube, meaning no welding and it will be mega strong
