NotSoBigBen Posted July 27, 2007 Posted July 27, 2007 Maestro Ah the bent MTB'r arrives, oh no sorry the bent frame MTB'r I know I know it was just a small dent but then the comment wouldn't be worthwhile to make!
JLDAM Posted July 27, 2007 Posted July 27, 2007 Mmmmm ok so less pedal bob can be find on the multi-link suspensions ? Who have you been talking to MichH ' date=' Bennie again ??!!! Anyway I have always said why over complicate anything if a simple solution will work and in most instances works better , like with the single pivot designs . But something else really tickles me . I went to a stockist of your new bike the other day as I am very interested to find out how their single pivot design works . But I could not find it ? So the salesman said to me it emulates a single pivot design !!! Did I hear him right ?[/quote'] Hi Dirt-rider, You are absolutely right. Our range of dual suspension bike is based on a single pivot design with a connecting rod/rocker link system. We call it the contact system. Here is a little explanation on it. A little extract from our brochure. I hope, you guys, don't mind me posting it here. "The Contact System is a layout made up of our own-design single-pivot point and a connecting rod/rocker link system. <?:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />Precise calculation of the pivot point location and the geometry of the linkages enable us to manage the suspension rate and therefore accurately adapt its feedback according to the type of usage the bicycle is intended for. It is fairly obvious, for example, that a downhill bike must absorb bigger impacts than a dual suspension X-country or enduro bike. We have thus tuned our downhill bikes? Contact System so that the suspension is much firmer at the end of its travel than that of the X-country or enduro bikes. This calculation is essential in determining the general behaviour of the bicycle, and is the first step in the development of each of our frames. In general, the Contact System is designed for : - Maximum traction on small impacts- Comfort throughout the entire suspension travel- A progressive suspension rate so as not to bottom out on big impacts. The Contact System is found on our <?:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Meta (X-country & Enduro) and Supreme (Downhill) range.When it comes to suspension, we often talk about progressivity without really knowing what it?s all about.A suspension system with a progressive rate offers high sensitivity on small bumps (and therefore tons of grip and comfort) and it gets progressively firmer as the impacts get bigger thus avoiding bottoming out on the biggest impacts.We illustrate progressivity with a curve showing the changing of the leverage ratio (wheel travel/shock travel) throughout the travel.For each COMMENCAL frame that we create, the R&D dept?s first step is to achieve the desired suspension rate according to the use of the bike. This is probably the most complex stage of development but it?s what makes the difference between a bicycle manufacturer (who design their own frames) and a bicycle assembler (who buys off-the-shelf frames and brands them as their own). Moreover, this step will determine the performance of the bike." Cheers, Jean-Luc
dirtrider Posted July 27, 2007 Posted July 27, 2007 And the first words outta his mouth he talks kuk !
dirtrider Posted July 27, 2007 Posted July 27, 2007 Thanks for that info . So in essence the bike behaves like a single pivot (sorry the rear suspension does)but uses multi pivot design ? But seriously it is not really that important since I still need to take one of DAD's bikes out for a test ride to feel it out .

Anybody can give a sale speech, on how well their system works. As they say the proof is in the pudding, and the best way is to test the bike, to get a feel for it.
RodTi Posted July 27, 2007 Posted July 27, 2007 Merida manufactures Specialized bikes and owns a large share in the company. They also produce many many other brands. The Specialized Brain technology is actually a Merida Patent applied to a Specialized Hosrt link 4 bar suspension. Oh right - I remember that now from the article someone posted here about bike companies... Still' date=' imo - and only my opinon [] - the art designer dude, and the "oh-let's-be-different-by-going-with-the-square-tubes-so-that-everyone-will-forget-that-we-own-Spez-because-our-bikes-look-so-different" dude, should be taken out to a wall somewhere at the back of that little sweat-shop in Taiwan, and shot. Repeatedly.Until they are all warm and sticky.And then - since their kind never die - they should be sent off to go and work in some bike shop in downtown Beijing. Ha ha.Try and see the lighter side of what, I now realise, might be seen as a bit over the top.But hey - the man wrote it, and then he posted it. RodTi2007-07-27 05:56:07

RodTi Posted July 27, 2007 Posted July 27, 2007 Man that's a beaut! Riding one it might look like you had a lightning bolt strapped to your, uhm, nether-regions. Of course - the bottle cage underneath the downtube would spoil that a bit... Unless it was a lightning bottle cage...Yeah - and you drank lightning !! Yeah yeah.. Or you just used a camelbak.

Thug Posted July 27, 2007 Posted July 27, 2007 It's an AM' date=' you do not fit stuff like bottle cages or bar ends. [/quote'] hehe Reminds me of the chap who won the Orange Patriot as a raffle at the SA Downhills at Gillolleys. Instead of selling it and buying a XC bike, he spent R 6k on it and converted into a XC bike . Bar Ends on a Downhill Bike.
GoLefty!! Posted July 27, 2007 Posted July 27, 2007 Most of the time' date=' it's much of a muchness and you will need to ride a few designs to see what suits you. Some designs use a single pivot design. This means that as the rear triangle moves, it directly compresses the rear shock. The main benefit of this is simplicity. (I stand to be corrected?) Some use a single pivot with remotely activated shock. The benefits of this are less pedal bob (i.e. you want the rear triangle t move when the bike passes over a bump, not when you apply pressure downward on the pedals. The other designs are usually multi-pivot, and usually try and improve the activation of the shock. The ideal is a shock that doesn't lose power on uphills, handles small bumps smoothly, but can still soak up the huge knocks. At the end of the day, try out a couple of bikes, find one you like, learn about it's rear suspension design, and MOST IMPORTANTLY learn how to argue that your design is far superior to everything else in the market! This does become tricky when your expensive Santa Cruz shares a design with the value for money Raleigh, but you will have to find your own arguments for that [/quote'] Your learned well young paduwan...Soon you will be ready to take the test and a Jedi become
dirtrider Posted July 27, 2007 Posted July 27, 2007 Ooooh Jedi master how wise you are ! Mampara now that bike really looks awesome and it has the design I so luv as well .
MichH Posted July 27, 2007 Posted July 27, 2007 What can I say GoLefty, it was a good thing Jean-Luc bailed me out! JL, thanks for all that high tech talk! Now I can use words like progressivity with confidence when I talk about my bike!!
