4bar Mono, SPP,VPP for Physics&Engineering buf

[Scott]

Just picked up this gem from the "Lose some weight" board at MTBR.  Not all of it is over the heads of the typical biker and they back up their conclusions with a ton of work.  Lots of myths taken out and shot too  I had to go to another computer to view as the AOL dial up here refuses to connect, yet road runner worked fine.

wow -

some rainy night i'm going to read it all -

the info on floating disc brakes and rear suspensions, in particular the vpp, was great

OP

  WOW! that is alot to take in.
Great job with tons of info.

Leaves you feeling a little "used" by the bikes companies marketing dept. doesn't it?  I especially liked reading that a so called brake induced lockout suspension design had that characteristic only while you're in a parking lot motionless, with the rear brake on-that once we're moving and the tire doesn't have a static contact patch, the suspension is free to move, in fact they claim our single pivots often outperform some of the multiple linkage bikes in this respect.....  I'm guilty of being convinced otherwise by nothing more than "suggestive marketing"

this is facinating......

i think the reality that one expereinces while riding is somewhere different though...

because....

....geometry of the frame, "mass" distribution (from the site mentioned), pedaling, the SHOCK all input to the frames suspension reaction...that's where the differnces are and have always been

what did i miss

I think you're right on the money Angus, and that's why they stress a ride on potential bikes is much more important than marketing hype, suspension design, or even other riders input-though I'd rank rider input high.

Ride-On Scott! [smiley=beer.gif]

being an engineer, and technically oriented, I have played around a bit with the linkage program.
It gives lots of info regarding the physical aspects of different bikes. I think it is a good guideline to see how different suspension designs will behave compared to what one may already have.
I ride the single pivot evo, and a 4 bar fsr, so I have lots of stuff to look at and compare.  My personal conclusion, after doing path analysis to all popular bikes: My current rides are keepers until they crack.
With the possible exception of adding a vpp type bike, and/or a long travel fsr.
My evo brakes better than my fsr, the fsr rear tire will skid and the evo does not. The fsr is better climbing and pedalling though semi rough stuff.
