I feel that the overlap of people who will be running a bash ring and a power meter is very small. But true, now they won’t have to make a separate quarq compatible crankset like they currently do.
Looks like SRAM switched from the dub direct mount (3 bolt) to the road direct mount standard for the new cranksets. Probably to prevent people from using the current, flat-top chain incompatible, chainrings.
Just placed a preorder at my local shop, they told me it entered their ordering system on Tuesday and they have quite a few frames ordered and coming in. They’re not sure when they will be in stock, but I’d imagine the alloy Stumpy Evo will be announced this weekend at SeaOtter.
