FSR is technically dual pivot, as there is two pivots separating the axle from the frame.

Single pivot isn't necessarily a bad thing, It just has to be done properly.

The trek split pivot design is still basically a single pivot, the split pivot just acts as a floating brake.

Konas are a linkage actuated single pivot design, meaning that the rear wheel has only one pivot between it and the frame. Linkage actuated single pivots (kona, transition, banshee etc.) usually have a main pivot that isn't high enough to allow for an axle path that has good bump absorbing qualities.

The Yeti 303 DH defies all of the know categories for suspension designs, as the axle path is decided by rails instead of pivots, giving a truly unique axle path compared to most standard suspension designs.

I have a blindiside and it absorbs bumbs quite well... as good if not better than my friends vp free.

so what kind is the yeti 303? i just got to wondering that.
hate to say it, but no idea, its got a wheelpath similar to a single pivot, however the whole rear floats on rails, there is on pivots the chrome part rides up into the front triangle

i think it has a multi pivot design since it has many pivots on the whole linkage design

its a floating single pivot so its pretty much like vpp so the pivot point will actually move up and down

the yeti 303 has a unique pivot system called the three-zero three

What it stands for, i have ono idea, their site should say somewhere though.

if you using a non single pivot system it is way better because the bike manufacture can set the wheel path so it can go in towars the bike then up or up then intowards the bike with a single pivot it just makes an arc

who told you that having the wheel moving towards the bike is a good thing? think about for a minute. you really need the wheel to get out of the way of the bump / rock / obstacle. if you have the wheel moving forward you are creating more pressure against the obstacle, and if it is a square edge you will really feel as if someone just grabbed your wheel. you really need the wheel moving upwards, ideally you would want the wheel to move up and back. (most well designed bikes are design that way)

actually its an advantage even the yeti uses it it goes up the comes in so its absorbs the root then comes back over using the power of the suspension so you dont lose any speed

i don't understand what yopu are trying to say. upward and rearward axle path is good for roots and square edges....it just makes sense. just like a fork. it moves upward and rearward.

In my 3 years of riding, I have owned 5 Full suspension bikes, all of which were Horst link bikes and I have never thoroughly tested any of the "virtual pivot" bikes or any other fancy suspension system so my opinion is a little biased, but I don't really buy into the axle path, leverage ratio thing. I'm sure it makes a difference but I sure as hell don't notice which way my wheel moves when I'm bombing down a rock garden or steep technical section, as for pedal feed back, if I'm climbing, my shock is locked out so I don't really care how much pedal bob the bike has.

For my next bike I would like to get something that has a more complex linkage design and see if its really up to all the hype but right now i'm not convinced that they are superior.

looks sick! I don't know where I would get the $$ for that one though.

the canfield jedi is just a vpp, and a verrrrrrry efficient one at that. the pivot point is like a few feet out infront of the bike im pretty sure.

It's not vpp, it's their own parallel linkage which is why it has so much rearward travel.

oh yea your right, i heard somewhere that its the same type of suspension design used in F1 cars, if im not mistaken.
