How many SRAM shares are you holding?I feel for sram. I really do. They did come up with something special with the chain retaining rings, get copied and really did lose some revenue.
I give SRAM a lot of credit too. XX-1 was revolutionary IMO. But they had to know it's not a particularly protectable concept. And as for lost revenue, let's not forget how much a lot of us paid for XX-1 cassettes before any alternatives were available, at which point SRAM suddenly figured out a way to somehow make it more affordable. They squeezed (and continue to squeeze) a huge amount out of it, particularly when you consider market share, OE spec, etc.
