Yeah, but the "extra" linkage isnt really doing anything is it?
Essentially just allows for the shock to be put in a different position?

correctly tuned suspension will make an incredible amount of difference as long as you have also set the rest of the bike to work all together.

for example tyre pressures make a fair difference to how the shocks will actuate under load and impacts also the lever ratios ie the ironhorse sunday has a 3:1 ratio but the end stroke is a 2:5 ratio therefore forcing through the last part of the stroke by retuning the shim stack and spring rate to match rider preference you can have a progressive shock yet keep you small bump sensitivity ie trail traction and large impact absortion.

for example some of the riders that i work with run a Vivid on an ironhorse sunday and found that the standard tunes did not offer what they wanted they either had the begining stroke to stiff and then the end stroke would blow through or the shock would wollow through the mid stroke, and they would have to run a softer spring with large amount of low speed compression to compensate. we have now re worked the internals and running the softer spring he is not blowing through the end stroke and he also has a good progressive feel with around 37% sag with no low speed compression added.

but for the average rider you won't notice the difference until you have some experience on a bike, but always get the best suspension possible then you can have a good shop/mechanic set it up for you to perform as best possible until you are ready to invest in tuning.

The other thing about full sussers and being overbiked: is being the fastest your only priority?

Depends what you want out of riding. I'd rather be over biked and maybe slightly slower on a track but have those extra inches to allow you to ride out of a big cased landing etc, or when you hit a boulder or something. A big bike helps get you out of all sorts of trouble.

Being able to ride the next day 'cos you're legs aren't shagged from riding your HT yesterday is good too.

Full sussers: helping the over 30s get up in the monring.

In regards to being fast.............Hell no. If it is yor only priority then i think your riding for the wrong reasons.

Me? First and foremost i ride for fun. Being quick and pinned comes with practise. If i didnt ride for fun i wouldnt ride at all. If you have fun,look pinned feel rapid, then thats just an added bonus to smile about after a rather quick run.

the giant dh team is a single pivot?
Wink never said it wasn't,

but the way the shock was controlled through the linkages made the bike ride very different to the typically linear single pivot non-linkaged bike. much better to be honest, but didnt make me any faster, if anything slower

I would say a little bit, theres alot of marketing hype for certain designs and what not but theye are made for a reason, weather they make you faster is a totally different kettle of fish IMO. Like i disagree with some statements about riding a HT will make you faster, it does make you appreciate the smoother lines and pick your lines more carefully but then your learning yourself how to ride a hardtail on a downhill. You get back on a Full bounce and you seem to be taking these uber smooth lines that you have practiced on a HT yet who said the smoothest line on a HT was the fastest maybe that gnarler line that was too rough to hit on your HT is actually alot faster on a bounce? In which case you would have to re-learn yourself to let go of that chicken s**t HT stuff and let the bike do the work and not worry about whats smooth to hit yes/no? And thats my opinion on why 1. buying a full sus to start DH on is totally fine and 2. why the bike you buy has a tried and tested good trusty design.

There is a difference between a linkage activated single pivot and a straight single pivot, as the linkage can manipulate the leverage ratios on the shock. it's essentially there to do the same as VPP but doesn't do anything to the axle path, only alters the progressive curve on the shock.

I think it's fair to say that suspension designs are better than they used to be, e.g. looking over a ten year period or whatever. So, it stands to reason that since part of this progression has been evolving designs then they must, on average, improve on previous iterations - even if year on year advances could be construed as marketing BS.

I also think the fact that there isn't a single best proven design is partially down to marketing and companies trying to differentiate themselves. But I also think that if the core stuff is present in the design (e.g a wheel that can move up and down, with damping to control the rebound and consideration of chain growth etc) then the human body just adapts to it.

Our legs are basically infinitely adjustable shock absorbers, I'm sure they automatically compensate for vagaries in suspension design. Like, for me, I've got used to riding my demo which feels like riding a stable platform that just runs parallel to the ground. Riding my mates single pivot Orange I can feel the difference immediately. But the feedback through the pedals means although it feels less stable, I kind of feel like the kickback through the pedals is helping drive me on. Could I learn to ride this faster than the demo? I dunno, maybe, maybe not.

I reckon pro/decent riders just automatically learn how to make the most out of whatever design they're riding to get the most out of it. No track/line/rider is the same, hence no clear winner as to the best system.

So the long and the short of it is I reckon *all* decent proven designs are essentially equal. And which is the best/fastest comes down to your preference as a rider, how you learn to use it and probably the track your riding too.
