I have tried a product very similar to Durafix to attempt to repair a crack in an aluminium bumper for a classic car. Even with lots of practice first the results were pretty poor. It was like kind of like soldering, but the area I was trying to fix was flat, I couldn't see your pictures but if the crack was where two tubes joined, then the Durafix might fill a bit better, but I wouldn't be convinced that it would be strong enough.
My friend fixed a carbon road frame that had a damaged seat tube, by bonding in an aluminium insert.
Great thread
I think the temperatures involved with durafix would be enough to effect the heat treatment
Have you got a quote for a proper repair, weld and heat treat if necessary. That will give you a basis for comparison
I took a demo Tracer out one day, lowered the seat post and managed to bend the clamp just tightening it! WTF if I can bend a seat post clamp.............
I know Intense bikes ride well but I have seen to many cracked frames to give them a go!
Any update on if any of this has worked?
Whoops... sorry, just saw your post 😳
Haven't actually moved on to repairing the frame, have in fact decided that I don't actually need it in all honesty, so it's now up for sale again (actually in the classifieds now if anyone's interested 🙂 )...
