SO on the advice of my . . who cares bought a mountain bike a Dawes 29'er full suspension because it was within my budget. Got it from Bikes Direct
I noticed on the page that Dawes called the suspension a 4 bar . . O I thought from the description in the 6th ed of Bicycling magazines repair manual that was good deal
So here is what transpired
i get the bike and it actually has a "Low pivot"
So i started sending emails This is to inform all who are new to mountain biking or those who want to laugh at the great length bike salesmen will go to hype there product
Great Job on Delivery
In your advertisement for the bike you said it was a four bar linkage "Dawes USA says "the 4Bar Link is the best suspension solution with supple ride response and control.""
In the Bicycle Maintenance & Repair book 6th ed on page 39 it describes the different types of suspension
Four bar linkage " Known as Horst . .or FSR linkage that minimizes bob and brake jack
Low Pivot A single pivot point , located behind the bottom bracket shell, allows the suspension to remain very active at all times. As a result, this design is most susceptible to bob and biopacing . Some low-pivot bikes bear a striking resemblance to the four-bar design described above . Here is how to tell the difference : The key to the four-bar or FSR linkage is the location of the rear pivots on the chainstay, just ahead of the rear dropout. If the rear pivots are on the seatstays above the dropouts It's a low-pivot, not a four-bar
I believe the Draws Roundhouse i bought meets the description of a low-pivot rather than a four bar Bikesdirect has advertised ("uses an Advanced aluminum frame that features 4Bar Link Technology) on the order page
If I am correct please correct your advertisement if i am correct. So that other buyers wont be disappointed with the handling characteristics of there bikes and blame it on the four-bar suspension. When it is, in fact, the Low -pivot known to cause problems http://www.bikeforums.net/images/smilies/frown.gif
There is no government agency that has an official definition of this linkage that controls commerce.
Thus, all manufacturers can apply their own definition.
We have our "4Bar Link". It has four bars that are linked with multiple pivots and provides great suspension action.
It is not a single pivot.
Thousands of happy riders are using these designs-http://www.bikeforums.net/images/smilies/mad.gif
Me to Dawes
Spoken like a lawyer/salesman
I would like the technical performance data on your "4Bar Link" please.
