really cool, but holy cow the proprietary parts on the front end.
if you bought that patent, you'd better have some chops to bring the whole design up to modern standards - or know someone interested in licensing it and doing the work to modernize it. That's assuming the patent isn't already expired, or isn't about to.
It is an interesting design with the linked brake. I could be really an amazing performing XC fork, especially with the anti dive but I suspect, much like the trust fork, it would be so expensive, even if you updated it to current brake standards, that it wouldn't be worth pursuing. I feel like standards for suspension are firmly ensconced in the dual slider fork world that breaking into any other paradigm will require cubic dollars and a planned loss per unit MSRP.
Maybe if early linkage forks had been better, AMP, Girvin, and leader, and had provided substantially better performance vs. the simpler slider forks then we would occupy a future in which sliders and linkages were both options but even looking at how few upside down forks are available indicates that it is hard to beat the standard fork. With the Red Bull Rampage being won by a dude on a single crown standard leg fork, it is hard to imagine how far they have come since the RS-1.
