Can't believe I didn't realise this before...
I shall enter my Santa Cruz Tazmon
[I'll up load a pic here later]
The first Santa Cruz Bicycles design, which after a couple of years lead to the simpler design of the Heckler, got them on the MTB map, but was expensive to make and could only be fitted with a Risse rear shock.
The fantastic dead end feature is the rigidly mounted rear shock, which then relies on an eccentric bush to allow for the arc of the shock pivot centre as it moves through its travel. To my knowledge, no other bike does this.
Compared to other rear suspension designs of the time, I found it noticeably stiffer laterally when cornering hard over bumps or giving it lots of welly out of the saddle. Mine has had about 10 years use on the current set of bearings and bushes without developing any play, which seems a novelty compared to other designs.
Disadvantages though are the limited choice of shocks (a modern platform shock would suit the single pivot design better), and whilst the bearings developed no play, my first set got quite notchy when trying to turn them by hand, so I replaced them after about 5 years.
( and its an e-stay too of course
