Not used them, but I’m struggling to see see the point. The last thing i want is stiffer bars and I’ve not had or seen loads of wider 31.8 bars fail.
I’ve had a few bars over the last year or so and some were just way to stiff – my SixC’s were the worst offender; even in skinny 31.8mm diameter, they battered the hell out of my hands.
I swapped for Spank Vibrores which were better but were an off shape despite being the same shape as my preferred Answer bars on paper.
I’m back on Answer Pro Taper’s now. The big thing that I think that makes them relatively comfy to the others is that they’re skinny. They taper down from the clamp bulge relatively quickly which means that there’s an element of flex.
