Exactly this!!!
It cannot pivot around the BB, it pivots on the linkages, not the BB, and for those that say it does, please describe how on earth it does so with no shock or indeed any pivots around the BB?!
Even so, it's still a URT design.
a virtual pivot is exactly that, virtual. It is not an actual pivot as some others here would have us believe...0 -
Ok i've watched and watched the video cliP, theres no Pivoting around the BB at all?oodboo wrote:According to the write up it does work while standing.

er...
huh? The virtual pivot point is the point which the rear wheel orbits as it travels. "effective pivot" is another name for it if you're struggling with the "virtual" aspect of it.
Any bike that is not a single pivot design, has a virtual pivot. On most of these, the pivot changes position during the suspension action.
The reason people design bikes with virtual pivots is because you can either
a) stick a pivot where you physically couldn't otherwise
b) have the pivot move during suspension travel, resulting in differing behaviour through the stroke.
c) Marketing
d) all of the above.
Edit: Actually, d) should be "any combination of the above"0 -

I guess you mean me? Maybe wiki will explain this better than I can

Good diagram here too of Giant's Maestro:
Though is worth noting the the IC or ICR is not always the same place as the virtual pivot.0 -
Forgive me if I'm wrong, but my understanding of this design is, that while the IC or virtual pivot maybe somewhere around the bb area, that bike does not physically rotate around the bb, there is no solid, servicable, bearing laden pivot around the bb as seen on the Ns soda... correct?0

kinda looks like DW-link & VPP, don't it?
