Broken Steel Jump Frame

[Nuffy]

Hi there

 

I have broken my DMR Trailstar frame where the downtube meets the headtube, just back from the weld. There is a crack almost the whole way around the tube. It is a 4130 cro-moly frame. Any ideas if it could be fixed? I don't know that I'll be able to afford a new one, but any ideas where I might find something similar?

 

Any help would be appreciated.

Take it to an expert welder. Its a DMR...its worth saving. I've seen one of those that have been welded almost 10 times!

I've habe three steel frames welded and they all were still strong afterwards. best is probably to ask your LBS if they know someone able around. surely possible to fix!

Thanks for the advice. I'll see what I can do. It would be great to be able to save it.

I've taken a visit to Cross Town Cycles and the guy there said that there was no way to fix the frame. The break is in an awkward place - starting on the weld and going round the tube away from the weld. This seems to be the problem. Welding the crack will weaken that section of the tube, and it's a vital area. While it may be possible to do the weld, it's unlikely to be strong enough to take more of the same riding.

 

So, next question: any idea where I may be able to get another steel jump frame?

 

Action Cycling has an Azonic Steelhead for R2000. This looks pretty good, but I was hoping for another DMR or similar. From Chain Reaction Cycles (mail order) I could get one for about R3000, but I think that's pushing the budget a bit far. I've phoned around, and none of the shops seem to be able to help me.

Why not ask CRC about the Brand X jump frames....? They only have the XC frames currently listed but perhaps they can get more of the jump frames?

 

They were below a grand and from the reviews it seems there are many happy owners

if you like the geometry and ride of the frame, get it welded and get them to weld gussets in place.
