I met with these guys over a year ago. They were 'almost ready' to introduce their product to the marketplace then. Seems they are still 'almost ready'. I also spoke to them about branding their own crankset (ala Ergomo and SRM). They weren't interested.
My feeling is that there are some technical issues or financial issue (or maybe even patent issues) that are holding this product back. I mean why get people excited about stuff when you don't have product or even a release date. Sram can do it because they are Sram. Quark is no-one. They have set them selves up so that the first generation (if there ever is one) better be flawless or they will be in big trouble.
I say danger Will Robinson. Danger.
