Saw this at a time trial this winter...

looks more complicated that necessary too..
From the same guy that makes the Marin bikes. That is an old model.
The new ones are like the new Marins - short link 4-bar bikes with VPP setup. Not sure how they work versus SC/Intense VPP or DW - haven't looked closely at them in a while. I test rode one of them when the first gen came out at Interbike and it wasn't that impressive but they've refined the design a lot. Ugly as hell still though...
Just buy a Marin if you want one:
Watch the Marin video with Shaums (the Interbike I rode the first gen 4-bar Marin was when Shaums was on Chumba). I test rode the F4 with Shaums that year. Lisa Sher let me borrow her's and he rode along with me. See 3:10 in the video to see how the current 4bar system works:
They had an older model a few years ago that looked even worse.
whats the point of a linkage i doubt there is any brake jack
Q: How many names can 1 person drop in 4 sentences.
Please come back once you can make a post that is
b. Contains information that is somehow grounded in reality, rather than being entirely random speculation.
i know this has nothing to do with the thread but its funny!
Who gives a crap about the bike, I want one of those badass beards!
That is ugly and complicated enough to have been engineered in Great Britain. Does it leak oil?
I think that those come in a spray can...
that seems to be the thing here now.. bearded MTB riders.
Finally have more women riders down there now, thats great
No but it has electrical problems.
They had a german consultant too
So their new models don't have the linkage fork thingy? That was pretty much the only interesting thing about their bikes.
Easier to sell if its not horribly ugly on both ends
The old version [non-four bar] was just a single pivot in the rear so really it was only the front end that was interesting other than the over use (well for that time since almost everyone is doing it now) of hydroforming.
The front suspension is similar to the BMW motorcycle front suspension. The main advantage on a motorcycle is that under hard braking the entire motorcycle squats, instead of nose diving, it also has less flex. The main disadvantage is weight and most non-BMW mechanics scratching their heads when they see it.
I'm not sure it the weight and complexity would be worth it on a mountain bike.
I'm pretty sure the real advantage to having a linkage system like this up front is to minimize wheel base shortening while going through the travel.
Hard to tell from this picture angle, but it seems like the front wheel path would be perpendicular to the ground (90degrees), rather than on a 68whatever degree angle
edit: disadvantage for DH
I saw one in the UK when I was riding. looked hard to steer in tight downhill corners.
FOXROX actually beat me to it, but BMW (I believe) was actually the first company to use that, but only it was on their motorcycles
And their suck-ass mountainbikes.
Our shop used to sell them to Asians with more money than sense, and they would always shear/fail at the lower front balljoint connection, just from hitting speedbumps.
That guys glasses look upside down....
Well, the nosepiece is right, so they are right side up, but they do look upside down.
I wonder if he has to shave under his eyes.
Ah we think so much alike. I saw it, didn't even look at the [slur deleted - jbp] bike. I said, "I want one"
Blimey, lots of nearly right info in this thread.
That bike was designed by Jon Whyte who was a designer for Marin before designing that bike, which was nicknamed Preston (after a character in Wallace & Gromit, British animated film characters) during the design stages due to its ugliness. Prior to working for Marin Jon Whyte had worked at the Benetton (now Renault) F1 team.
The front end of the bike is lighter than equivalent (of the time) telescopic forks, and got decent reviews. The type of linkage was originally designed by a British engineer called Norman Hossack for use in motorcyles, it is know as a Hossack or Girder fork. Hossack had worked as an engineer for the McLaren F1 team. BMW picked up the idea for free once his patent had expired.
Chuck Norris is gonna be pissed when he finds out someone is usurping his beardness. I wouldnt wanna be Mr Upside down glasses guy...
FWIW that is a 'telelever' front end, which is very different to the linkage on the Whyte bike.
