It can be seen in this pic just under the front mech clamp (not my frame but same unidentified hole):
Anyone know what its for?!?

Make the brake work almost as well as if it's on a bike with a proper 4 bar back end.Posted 6 months ago # -

Where did you get the frame from?
I really enjoyed the play about I had one a few years ago.

Think you will find it is a proper four bar back end.

Or more accurately the faux compensator

Ahh I think this is a common misconception, let me help you to sort it out.
Whilst I can't see properly on the white bike, the green bike above is defo a single pivot. There is on straight unpivoted bar between the frame and the back wheel, therefore the back wheel will follow a circular arc whose radius is fixed at the length of that bar. All them other pivots will just change how the shock is compressed.

it's not tho is it? It's a faux bar, no pivot on the chainstay. AKA single pivot with linkage driven shock albeit now it looks like (from dezBs pic) a floating system now ala trekedit sorry slow typist here

Excellent, all the arguing about the linkage means nobody has noticed the amount of bird poop on my drive!

Err no it is. Its the most simple version of the four bar design.
http://mtobikes.com/four-bar-linkage/
The most basic four bar linkage design is the ‘Faux Bar’
Oh look, you're wrong.

Luckily the people on here with brains don't need to visit a website to know that its actually wrong. That makes you and the author of that site wrong. Although in his defence he states that "This linkage still has the axle mounted on a chainstay which is directly mounted to the mainframe via a pivot, exactly the same as a single pivot design, and so will have the same axle path characteristics"
Which in anyone else's language makes it a single pivot. Although we will forgive you as some people like to call a faux bar a four bar, even though its not. The clue is in the title (its the faux bit in case you missed that)..
Anyway your link reminds me of this:

faux - french for false.
i.e. its a false.
its a four bar fsr wanna be ( a single pivot linkage driven bike)

Own a Kona by any chance, flow? Getting all defensive?

"people like to call a faux bar a four bar, even though its not"
Unhelpfully I think this also includes Kona, or at least their marketing/advertising department

Its not. Its effectively a single pivot with a linkage driven shock.
However its so close to a 4-bar that nobody really notices the difference.
Nice bike. Enjoy it.

Presumably the designers think that too, otherwise they'd have fittings on it for a floating...
Oh
