    what sort of riding will you mostly doing?

    for more technical stuff, where you will spend time balancing your weight fore-aft of the seat and doing tight turns, a smaller frame will probably be of advantage, and the M/17.5" could be the way to go.

    for more firetrail/road/flat riding, a larger frame will be more stable, like the L/19", which will stretch you out a bit more (ala roadbike).

    probably the M/17.5", but obviously try in the shop first if you can.

    I would say that there is now way you would want a large, that would be too big for you. I am 5'-10.5" tall and would ride a medium for any techical singeltrack use. My GF is 5'-3" tall and rides a size small, it fits her perfect.

    I would say go with the size medium.
    There is no added value to my participation - in fact, just more confusion.

    I'm 5-10, 33 inseam, have the O5 SJ medium. It fits me fine. I ride technical, rocky, rooty, muddy, loggy and slowly.

    Thats interesting iam 5'10" and 31 inseam.i own both a med and Large sj120. The Medium is for sale frame only on Ebay as i found it to cramped.
    I ride alot of technical rooty stufff the odd drop to 3 feet and some small maybe 2 foot trail jumps.

    I found the stumpy sizing to be on the small side and where i have always riden Medium in say giant i ride a large in specialised.

    The answer has to be try to ride one of each size, or like me you may end up regreting the first one when you get to try a freinds.

    I am also a similar height at 175cm (I think that's 5'10"ish) and have always ridden a large. My inner leg is 75cm and I feel comfortable on the large. I have tried medium frames and have a medium hardtail and it just feels too cramped. There's nothing worse than feeling squashed in - it's easier to shorten a long bike than extend a short bike I reckon.

    The Stumpjumper is quite compact feeling anyway, because of the trail-oriented geometry. Don't discount a large frame - it's not really that big.

    Edit: Ok I didn't read that you were 5' 6. Take my thoughts and drop it down a size! I would think a medium would be better than a small for your height.

    I'm 5'10" with an inside leg of 33" and am ok on either a medium or large Stumpy. I do prefer the medium though, as I feel that I have more control over it on technical stuff. If I was to race cross-country then I'd be on a large. As for yourself at 5'6", there is no way you'd be a large frame, so you should rule that out straight away. I reckon your safest bet would be a medium, but you should try to get a shot on a small just to convince yourself.

    This reflects my experience as well. I'm 5'10, 32" inseam, longer than average arms. I bought a medium 2004 SJ 100, based on my riding preferences of technical singletrack at generally slower speeds and what I thought was the conventional wisdom to size down in cases of borderline size choices.

    That bike was OK, but after several trips over the bars and also after reading that several people my size were happier with a Large, I sold that bike and bought a Large 2005 SJ 120. I am MUCH happier with it and actually feel in better control, even in tight situations, despite the slightly longer wheelbase.

    I agree that there is no way you want a large. Probably a medium, but also try a small if you can. As the above posts illustrate, even people the same height reach different conclusions about what feels best to them.

    I'm 5'9, but have a longer torso/arms than most females. I have a Large 05 Stumpy. I like it.

    Either way

    I am 5'10" and have a 30" inseam. I went with the medium because I found the specifications very similar to the 18" stumpjumper comp hardtail that I had previously owned. I tried the large but felt to stretched out, so I went with the medium. Consequently I could have gotten the large and thrown a shorter stem on and been fine.

    Yeah, I do have the Enduro stem (90mm) on my large stumpy.

    Just to continue the stem thing, in case you hadn't already noticed the small comes with a 75mm stem, the medium a 90mm and the large a 105mm.

    So say if you threw a 110mm stem on a medium you have a large correct?

    I'd say that by playing around with stem lengths and the adjustment of the seat on the rail there is a fair amount you can do to adjust the feeling of the bike. But I wouldn't say that a medium frame with an appropriately longer stem would be the same as a large frame.

    The length of your stem does considerably affect the feel of the steering, so there is more to it than just matching the combined "top-tube plus stem length" of the frames. Of course the wheel-base is also different too, but I dunno how much you'd be able to feel that in reality.

    Another thing to be aware of (but maybe not as important) is that the small has a crank length of 170mm whereas on the medium and large it is 175mm. But I wouldn't let that concern you too much, unless you feel that you have really short legs for your height.

    Get your ass on a medium and a small if you can - it's the only way to be sure.

    I bought an '06 Stumpy FSR here locally. When I was testing and finally getting sized, they replaced the stock seatpost with a Thompson on a large frame for me to get the seat adjusted forward a bit more. I'm 5'11" - 6', but my legs weren't hitting the right angle when they had me on the trainer.

    Go someplace that can get you sized up correctly from the start before you take shots in the dark on replacement pieces.

    I'm about 5' 7", but with a smaller inside leg. I ride the 120 in Small as I found the Medium just too much of a stretch up. There are times I'd like a more stretched out position (seat to bar), but that's mainly on longer, easy sections. I tried a longer stem but that made the steering too twitchy. For tight twisty stuff, I reckon the Small is about right.

    In any case, check out your LBS. If it's like mine, all the demos are Mediums - so try one and work it out from there.
