for full suspension bikes? I'm familiar with the motorcycle world where guys are always complaining that suspension has been set up for lighter people.

I'm not huge at about 205, but the thought just occurred to me as I am about to buy a Fuel EX8. I'm no doubt heavier than your average rider.

Thanks!

So they do then? I'm totally new to this.

I suppose the question i should be asking is how is an EX8 set up from the factory? Any good for someone of my weight if I'm not going to be jumping it to any great extent (at least not right away).

well..it will matter..since you will have to setup the air pressure or get the correct spring...

but at 205, it shouldn't be a big problem in most brands models...

Yes, I learned the hard way.

When I bought my first full suspension bike I mistakenly trusted the LBS and tried to get used to a fork sprung for a 175 rider (I'm 220) the size fit but the suspension was way to soft, I'd practically have to drag my bum on the rear tire to use the front brakes so as to not dive the front and go over the bars :)

It wasn't just the Large Cannondale I bought either the XL Fisher felt soft as did the XL Giant.

Its tuff to find a bike that fits I have yet to find a LBS that will set up the bike for a test ride, we just went through it again (the opposite actually) for my 100 pound wife she rides a medium and could not get the rear shocks on any of the bikes she tried to sage at all.

regards
Ray

Yeah, weight matters a lot on a mountain bike. The fuel should have air suspension fr and rr, so it will be tuneable for rider weight. You will need a little more than average, but still well within the normal tuning range. Ask your shop about a shock pump. It is like a tire pump, but is designed for tuning air shocks. Very low volume/high pressure pump.

Warning-if you don't know what you are doing, you should ask the shop to help you with an initial "ballpark" set-up. The problem is, many shop employees don't really know much about how to set things up the right way. You might luck out and have a good one, but too many are just salesmen. If in doubt, ask if the shop's mechanic is around-that may be your best bet. (Sorry, but I have two buds who recently bought bikes from two different shops and neither bike had spring rate even close, I have also test ridden bikes at other shops where salesmen had no idea how to set up for my weight)

From your initial set-up, use the shock pump to play with settings 5-10 psi up or down and try to find your ideal settings. Just sitting on the bike should give somewhere around 25% sag.

As you figure out what pressures you like fr and rr, write them down someplace safe so that after sitting for a long period (winter) you can quickly get things back to where they should be if you have lost a little pressure.

I run the Rock shox Pike coil and the firm spring , I'm 90kg in my gear
standard spring is 70-80kg, and extra firm is upto 100kg after that I was told it was best to change to an Air Fork. and they do softer springs also.
My rear shock is coil Fox DHX-5 and again changed the spring for my weight and make of bike, different travel and pivot types determine spring rates also.
I spoke to TFT in the UK specialists in suspension, it was a great help.

weight absolutely matters. I'd guess it matters more with mtbs than with motorcycles because the rider is so much higher percentage of the total weight.

at 205# you can easily get most suspension set up for you, but if your bike uses coil springs, I'd bet the stock springs aren't right for your weight.
Unfortunately springs are expensive (for what they are) and there is some trial and error involved in finding the right rate. I've had some luck with ebay - there are a lot of riders who accumulated a spring collection while looking for the right one.

I'm 220 and have an ex8. Like others said, it has air front and rear. The bike comes with a shock pump.
Hvae the shop set it up, but on the trek ex site, it has the suggested air settings for different weights. You will have to fine tune, but it will get you close.
Btw, I bike will be fine for 205.

I have that exact bike and weigh 210. Suggest per the fox website is 90-105psi front and about 170 rear. I can tell you that with that much in the front there is now way your gonna get 25%sag on your fork. The rear is pretty close. I guess weight bias is more to the rear on this bike. Im running 65psi front 160psi rear. I don't do huge drops or jumps but like fast trails where I can catch a little air. I haven't bottomed out yet, using about 85% of the travel on both ends at this setting. Just enough left for one of those jumps that shoots you up farther than you planned:D .

Like Joules confirmed the coil sprung forks and shocks are a bit more difficult to set up as you have to get the right spring weight ... but for air sprung forks and shocks, PP, has provided you the heads-up, it is just a matter of changing the amount of pressure in them to get the right setting ... higher pressure for heavier riders and vice versa ... but there is a limitation to that as well, but you should be fine ...
