That's where Josh Hon keeps going wrong...he lacks the upper class accent
The problem with adding extra bracing struts or any kind of internal or external abutments is they require welding in position. When you take into account the fact that alloy welds unlike steel can be significantly weaker than the metals they're fusing together thus you're compromised, more could well mean less so to speak.
I have to say the sight of a weld running along the bottom of an alloy bike holding something in place designed to strengthen the integrity of the frame does nothing for me. Instead of a Band-Aid why not just build a stronger frame in the first place. I think I'll stick with the improved latch as the key to it.
I'm sure every bike builder out there is not suddenly welding more material to their frames in panic they could be next, however I am seeing improved hinge and latching systems cropping up on many brands.
