man, i'm shocked 
(i don't know if there is already a thread about this, but i did a quick check and i found none)
i was going over some mountain biking websites when i stumbled upon this:
bikechecker.com/
there's a VERY GOOD software called linkage. here's a quote from their website
Linkage is a powerful and easy-to-use while still well-featured 2D suspension analysis software for Windows systems, focusing on mountain bikes, but also capable of simulating other linkages.
Linkage also provides a user-extensible web library of bike models to help bike-enthusiasts compare different designs or publish their own ones. Linkage comes with data files for many bike designs already on the market (or past models).
Main features:
* simulation of all popular full-suspension bike frame systems from single-pivot swingarm to four-bar linkages with additional shock driving linkage ("6-bar linkage")
* calculation of linkage forces by a kinematic model, allowing different shock-setups
* front fork movement simulation for examining different scenarios
* comparisons allowed on diagrams to easily recognize differences between different designs
* multi-window working environment with numeric or mouse input
* creating new designs quickly using photos
* export all results in high-resolution graphical or text formats
* calculation of chain related changes, as well as "pedal-kickback"
* more than 60 existing designs included
i'm actually very impressed with the software. it's very technical. i'm trying out the demo version but i'm seriously thinking about purchasing
but this is not what shocked me most. after reading the application notes, i stumbled upon an essay called path analysis by ken sasaki.
read it here www.mtbcomprador.com/pa/english
it's a difficult read (very technical, and, as claimed by the author, "The level of difficulty is referenced to a typical person with about a year of good solid college physics") but it's worth it
IT CONTAINS A SECTION ABOUT Flawed Theories and Bogus Marketing (chapter 5). it stirred up conflict on bike manufacturers especially on ellsworth regarding their ICT, GT with their i-drive and Kona with their, er, marketing

PEACE ;D
and I doubt it ends there hehehe
