Does it matter how shock is mounted

I'm looking at a couple of full suspension bikes. Most of the models have the rear shock mounted in the vertical position along the seat tube. Some had that shock in what looked like the upside down position compared with the other models that had the lockout lever on the top vs the bottom. Does that make a difference.
Also while I'm at it. What's the difference with a rear shock mounted under the top tube vs in the vertical position along the seat tube.

I always prefer the front shock to mount below the headset. But I'm picky. I'm also a believer in hardtails, more power to the chain.

Unless your racing downhills you probably wont notice a huge difference. Try a few, hang out where bike owners hang and talk to them personally. They may let you take theirs for a spin.

Be patient, many good riders will be more helpful than me.

It doesn't really matter whether the shock is upside down or not. As for the difference in suspension designs, there are hundreds of arguments as to which style is better. To me, the swingarm mounted to a vertical shock is one of the oldest designs, and the one that a lot of manufacturers keep going back to. Trek, Kona and (up until last year) Specialized have all used it. However, many great bikes use design that mount the shock horizontally on the top tube, like Cannondale, Jamis and (this year) Specialized. I don't think it makes a huge difference, but try a few different types and see for yourself.

Also, FS bikes are not only for downhill, please take Daspydyr's advice with a grain of salt. FS bikes have now spread to every part of mountain biking. They have their advantages and disadvantages, just like hardtails, so one bike design isn't inherently better than the other.

I don't really know the reason why, but I more often see the shock mounted under the top tube on bikes that are more racing oriented. Fisher's Hifi 29er is an example. Specialized's Epic is another.

Interesting question. Hopefully someone with more knowledge that I have will jump in here.

BTW, what models have you been looking at?

if you look at the two sette models (ACE and Flite) from price point,
the XC one (ace)is horizontal, while the Flite, a more AM suited frame is verticle.

IDK why.
I ride a kona dawg, and the verticle seems to work fine..

There is a fairly decent intro article in Mountain Bike magazine this month about shock positioning, leverage, etc, etc. I'm no expert on physics and stuff, and the article gave me enough information to be dangerous .

This thread reminds me of one I saw a few months ago on another mountain biking site, where a guy measured the piston on his shock, found that it was not 5" long, and asked why he had paid for 5" of travel when his shock was only something like 2.75"
