Alchemy Bicycles, a Colorado based frame manufacturer, had on display their new Arktos 150mm All-Mountain machine, which retails for $3,750 USD (frame and shock only). Handbuilt in the USA, the frame features Alchemy's Sine Suspension, which was designed by David Earle, one of the minds behind Yeti's Switch suspension platform.
Sine Suspension, named such because the leverage curve resembles the shape of a sine wave, is progressive during the first 85% of travel then transitions to a falling rate for the last 15%, This is done in an effort to utilize all of the bike's available travel, despite the progressive nature of an air shock.

Keen looking suspension design, like an SB66 with micro link instead of the Switch perhaps. Makes me wonder... whats in the box? Head-angle (do you hate tall people?), Seat-tube length (droppers be gettin' longer and if they are slammed, u got prollems) and reach (what do you have against tall people?) could be brought up to date, BB is a little high, I like the chainstay length but shorter riders will find it a bit long. Long live 'Merican manufacturing doe.

Also curious what's in that box above the BB.
Looks like it might be ripping off Speedgoat's design.

the frame design is designed by the same guy who designed SB66... Have no clue why Alchemy still use it...

According to an article on bikerumor.com, this bike uses a threaded bb.
