Giant NRS 3 XTC 2003, Tail suspension
I currently have the 2003 Giant NRS 3 XTC, and am slowly converting it to more of an all mountain bike that i can take bigger hits with. I currenty putting new rims and tires as well as a new five inch front shock. The only problem is I weigh 190 and when i put enought air in the rear shock to take some bigger drops and jumps it turns really stiff on the trail, I was wondering if there was any tail shock that i could replace it with to give me more travel????
You are starting with a wrong frame for AM.
You are a large fella and you want to do drops and jumps after you jack the front end up of a XC race bike? Yikes!
Welcome to mtbr !~!

I'm no NRS expert... I think the NRS is designed to have no sag so there are chain forces counteracting the suspension. So this means it's designed to use travel when the shock is at a pressure for no sag. Lowering pressure and it will really go through travel and increasing pressure would make it really stiff.
I think the older NRS's were somewhat progressive in leverage curve ?~?
So you want to increase the travel, which means you need to fit a shock with a longer stroke. This means the back tyre/or linkage pivot would most likely end up hitting the back of the seat tube. You can let the air out of the shock and bottom it out to see how much travel it has left if any. Assuming you can get a shock with a longer stroke with the same eye to eye length. If you have to increase eye to eye shock length you will change geometry, which may be good or really bad thing (often bad).
Maybe post in the Giant Forum... there should be NRS experts there.
I have a NRS 03 dual suspension too, and I weigh 200lbs. I have a 100mm skareb on the front. I just moved to CO from WI and began riding more single track as opposed to XC.
It is a XC race bike, it climbs great, but when I start descending I slow down because my friend has a XTC hard tail (similar frame) and he rides single track and his frame got a crack in it near the BB, so I'm a bit hesitant. I've had mine for 3 years now its okay, but if you do more than 3ft drops regularly you're going to brake you're frame.
Also, because its a very thin frame, it doesn't take to dents very well. I have a few dime size dents that are about 0.125" deep. I know eventually its going to brake, then I'm going to buy a more all mountain bike that can climb decent, but handle more free ride type descents.
