Shimano Patent Filing Raises Electric Questions
@deadmeat25: They're outselling downhill, enduro, freeride and slopestyle bikes combined by a large margin.

Shimano Patent Filing Raises Electric Questions
The picture is for a flat bar road bike... or did the caliper brakes on the rim NOT clearly give it away to you ?

Wyn Masters' Prototype GT Downhill Bike - First Look
"Routing the chain up and around the main pivot allows the suspension action to be largely isolated from pedaling forces." Except... that's not actually the point the wheel is pivoting around. This is a 4-bar horst link... has a virtual pivot point at the point in space that the lower and upper link pivot paths... come together.

Now THAT Was a Bike: 1995 GT LTS
"The suspension layout is a modified version of a Horst Link design (GT paid Specialized a licensing fee)," CORRECTION..... Specialized didn't buy the patent until Amp Research decided to get out of manufacturing bicycles around 1998, and part of the reason they sold it to them was because companies like GT refused to pay after they'd been using the horst-link on their bikes for years. Amp didn't have the money for lawyers to enforce the patent properly but well... guess who did... this is also why GT developed the I-drive linkage at about this time period.

The Short, Turbulent Life of URT Suspension
A case could be that John actually ripped off the idea from others before him. Roo Trimble had produced the whiz-bag suspension design and publicly shown it in magazines two years earlier. Also the Catamount MFS URT was developed independently of the sweet spot at about the same time, had its pivot in the center also, and had its own patent.

The Short, Turbulent Life of URT Suspension
For shame Richard... 990 would have been a hardtail, the beam bikes were the 9### series model numbers such 9000 or 9500.
