If there is identically one manufacturer sourcing a replacement, I'd call that proprietary. Even though Herse used that BCD in the past, they don't make rings anymore. Back then you could only get a Herse crankset with a bike. I get your point, though.
$385 does hurt, and it's only going to come down if they are wildly popular, and lets face it, they won't be. At the end of the day, though, it's hard (impossible) to find a cheaper crankset that is lighter, lower Q and offers a wider choice of rings. White Industries are $40 cheaper, weigh ~100g more, have similar (half-proprietary) ring choices, and a wider Q factor (150mm vs 142mm), but they are MUSA and come in lengths. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
