Bars can snap....I'm a phobe. My last non Ritchey bars were alu 5mm wall.
I dislike bar flex, and it will weaken the metal.
Now I'm using a bolt on Alu brace, I was into the Bontrager Crowbar.
Non suspension and small jumping - I do put a lot of force pulling and pressing on the bars.
I'm running an older chromed, chromoly Ritchey stem to the original threaded solid fork. (no bolt down faceplate.)
So I'm a bolt on guy, not expensive bars, but reinforced. I don't mind the little added weight.
Is this a good idea with mid level component metals?
Bontrager was a welded brace, mine is moveable so you can adjust the amount of resistance a little.
