Interesting bike - can't have got many out of the showrooms - did AS get sued for using the Horst (Sinyard) rear linkage then...? ;-)

looks a lot like the Univega Ram design that CRC was selling off cheap a while back – perhaps it's a bit of badge engineering?

Doubt there's much wrong with the design if it's a horst-link though

 

[gump]

looks like a single pivot linkage shock, or Faux bar as known in scary modern terminology :?
But does look v similar to speccy

Definately a four bar with a Horst.

£550 seems a bit optimistic though, let alone £750.

definately not - needs the pivot on the chainstay to give a change in rear axle path with sus movement

quote from the patent..
1. Horst-Link McPherson Strut

Pioneered by AMP Research, and Used by Lightspeed, Rocky Mountain, Intense,
Turner, Specialized and others.

The basic operating principle of these devices is illustrated in U.S. Pat. No.
5,509,679 to Leitner. As shown there, the lower pivoting arm or chainstay's pivot
axis is located at or below the horizon point of the tensioning run of the drive
chain of the smallest chainring, and a rear swingarm pivot or lower link is located
in front of the vertical axis of the rear axle and below the horizontal axis of
the rear axles. This location provides a binding action, mentioned above, that
resists chain-induced "jacking" up and down movement of the suspension. Among other
things, the resistance to the chain-induced "jacking" is established by creating
additional torques to counteract other torques and thus results in the aforementioned "binding".

IIRC Horst links are on the chain stays - not seat - soo 'faux bar'

Oh yeah. Being dumb tonight.

To the back of the class.

 

[gump]

made me think!

Yuk

Don't think it of very high quality, RST shock, pressed steel rear links, heavy as lead like my cro-mega :c

Just a question..

When did the last Alpinestars bike roll out?
