    Analyse any bikeís suspension kinematics ONLINE

    Thatís pretty cool!

    If anyone is willing to pay and share the Yeti SB130 analyses, thatíd be great

    It'd be interesting to compare the analyses from both.
    Do the math.

    Yup.

    For the comparison, not the 40Ä

    Why not just do your own for $25 of any/all the bikes you want? The library listing suggests that it can do the Yeti switch infinity slider/pivot and the R3ACT telescoping link as well as ordinary pivots.

    Iím not even bothered to be honest! But thatís a cool option for someone whoís leaning toward 2/3 different bikes and wants to know the real difference between them before buying.

    Curves and numbers are only curves and numbers. The real difference is the one felt by the rider out on the trail, and if you can't tell then... go with the one that's got the colors you like!

    wants to go beyond the traditional bike geometry if you prefer

    The ęreal differenceĽ was a bit misleading.

    If a bike has 70% AS, it's going to pedal like a wet mattress. It's useful enough info to just skip some bikes and not waste the test ride.

    Those numbers are extremely valuable! I'd say that they're the real, true difference. Everyone gets excited about their bike and often thinks it's the best thing ever. Hard numbers show of something is actually fesible.

    The leverage curve shows how it'll feel off the top, at bottom out, and gives you a decent idea of what shocks it can use.

    Of course they are! How many people buy a shock with a random tune and hope it will work fine? Do they know their leverage curve so they can match it with a tune? Probably not, and I donít blame them because 99% of the time the tuning code is not even advertised when you buy it online. But if you understand all that OR can get some help from that kinematic/suspension analysis website, then you will make an informed decision/purchase. Not based on color this time

    It's no longer 1998, we now have a pretty good understanding of suspension kinematics and why things work or don't. Not every manufacturer knows what they are doing, some are still flinging **** on the wall to see what sticks, but that is much more of a minority now than the overall rule and we can accurately predict behavior based on these numbers.

    The expiry of a lot of patents in the last 20 years have opened up the suspension market considerably.

    Plus 1x drivetrains so chain-line is less of a factor.

    I wouldn't really agree on the first part, you seem to be inferring the FSR. Although FSR expired, it doesn't really offer anything over a decent linkage single pivot and arguably is inferior in stiffness and braking, lots of euro companies were already making them though before the specialized patent expired, obviously a few companies have jumped on board now, but these vary widely in how good they are, some with steep AS profiles that still pedal like mush, some with flat profiles that pedal decent. I'd say a much bigger factor is understanding and designing for the latter goal, which can be had with a FSR or single pivot.

    I'd put it much more on understanding kinematics and designing with this in mind. SC, Intense and Yeti all have managed to get around other patents at relatively stable AS figures until mid travel or more, devinci, evil single pivots, etc...Doesn't take parallel linkages, but that is one way to do it. Single pivot, parallel linkages, FSRs, none of them guarantee good suspension.
