Would like to see how it holds up. I've a Silverback Alpine with a cracked frame (due to an idiot who drove me off the road). Maybe somewhere along the line you could have a look at mine? Cracked where the top tube and seat post meet.

Wouldn't a laser welder be a better option here? There's plenty of small companies around now days with them and they can weld just about anything (if the operator is experienced).

Hi wiledog , being a long term experiment I cannot tell you if it will hold up as of yet.

Although the stresses in the frame are much less at that particular spot than in mine it should theoretically hold up longer than the weld on the bike I did. 

A few things that count in your favor would be the fact that the initial crack was not due to fatigue but rather a brittle fracture and that it is easier to weld in that spot.

I will ride my frame until January and If everything seems fine I will contact you regarding repairing your frame.

I rode the frame for the first time tonight for about 10minutes with the accelerator on. I did a few bunny-hops peaking at 2.5g's. Tyres and shock were at operating pressures.

everything held up good for now.

I will post photo's of the build so far tomorrow.

Here is a photo of the bike so far.

As mentioned previously it will be a commuter bike and I've rebuilt it with some used components. 

Including a cracked fox fork and gummed up Slx brakes.

I will attempt to repair both of them as well.

I am going to redo the drive-train with a Rapide single-speed kit.

The picture posted here is as the bike was tested.
