not the trail version, just to specify but the shorter travel SX

I have a couple of friends who are having a blast trail riding their Transition Doubles. I have been looking at the new Specialized SX in that regard. I would like to take it to jump parks and stuff but also want to trail ride it. My thoughts are to use my lyrik solo air and since the frame is tapered, run a flush mount bottom cup to keep the front end low. If that does not ride well, i can always use travel spacers to drop the travel to where desired.
What are these frames building up at weight wise. Looks like there is plenty of seat post adjustability and the new type of front deraileur mounts. Any downsides people can think of to this idea? I want a 67'ish degree head angle and like the idea of low and short when I describe my ideal trail bike.
Specialized advertises bike with 68 slackest setting and low 12 bb height for lowest setting. They don't say other settings and they don't say what fork travel that is with. Any more info? I am looking at the 09/10 model styling for this project. Realize its early for the '10 stuff and that is why there is so little info out there.

I ride a 09 white SX. The bb height stated in their web must be with a 120 fork or 100 fork with huge tires, cause mine with a fox F100 and 2.1 tires bb height is only 305mm which is really a bit too low for general riding.

Apart from the low BB it's an awesome bike, for trail riding seatpost height should be fine if u are not taller for 5'10". I am 5'8" and the size S fit me perfectly. Frame w/ shock is about 8.5lbs, whole bike came in at 30.5lbs, not light but you don't feel it when riding.

I recomand keeping the bike low with a 100 or 120 fork, as it make the bike rail corners and at the same time stable in the steep high speed stuff. Superb fun and super confident. With this frame u don't feel the need of 6" inch travel. I say go for it!!

Great responses, thank you. I will have the winter to ponder the decision but am really liking that frame. I am wanting a bike with less travel but solid for parks and such, that frame is the most appealing to me right now. Seat tube angle looks good for pedaling but wonder how the short chainstays will affect it. Horst link is always pedals well. Do you trail ride yours? Do you feel it is much of a compromise if any doing that? I am 6'2" but would be transferring my KS adjustable seat post so know I could get the extension I need. For reference, I am coming off a 6 inch bike weighing at 33 lbs, and before that, another 6 inch bike weighing 41. I was mostly wanting to keep getting lighter if possible, under 33 is fantastic.

i dont think putting lyriks on SX is an good idea, long travel makes the bb too high + meaning you cant hit jump or drops at decent speed unless theres a long enough run up
you want something shorter like fox F120 or similar 120mm travel forks
you can also run step down headset to use stright 1 1/8 steerer forks

its possible to build it abt 33lbs, just dont use stupid heavy steel parts on it and it would be fine

the 09 and 10 are basically same frame but different colour
my mate have reveived his SX frameset like last week and building it up by nxt week so yh i will get him 2 post some pics here:)))

Yeah, I figured the lyrik would be too tall even with a flush mount lower cup headset and a 1 1/8 steer. But the nice thing about the solo air is I can use travel spacers and lower its travel. I was thinking flush mount with 140 would give me a 67'ish degree head angle and still in the 12's bb height. This is all speculation though so would love to hear from as many people who have this frame as possible. Pics would be great also, the frame is hot looking and very few people seem to have them.

The SX do pedal ok and I do trail ride mine. Apart from the low bb, there isn't much of a compromise for general riding. It is heavier than a normal 4" bike, but nothing too serious. I think 110-120mm is the optimal front travel, any more you may find the hori. TT too short for any uphill work. Here is mine (cell phone pic):

Built of this '05 frame a few months ago and I could not be happier! It is snappy, fun to ride, plush for bigger hits, but still pedals well and has fairly adjustable geometry to suit most riding styles and applications. I have a 7.875x2.25" RP23 on there and the chip that gives a higher BB and steeper HA. The larger shock gives it almost 5" of rear travel and make the bike handle superbly. This bike rips. With the kit on it now, it can handle a bit of everything and still pedals very well. I know its not the newest version, but if this is any indication of how Specialized does the SX, then I would not hesitate getting a recent frame.
Old pics, but you get the idea. Since added a 36 Talas RC2, XTR M970 kit all around and Schwalbe Big Betty's.

What is with the color? Is that a SX trail with the shorter shock? I didn't know they came out in silver.

It's an SX slalom, 4". The frame is a paint sample I got from the Specialized B2B blem site. So far as I know it's the only one out there. It was a pain in the arse trying to get a shock for the thing. Fox doesn't make a 1.5" stroke air shock. Had to have PUSH reduce the stroke of a shock I had.

Just bought a 06 from ebay

The frame is black to white lightning bolts. Just got done building it up and it feels like a ripper!.. I also got a 09 Marzocchi 55 ATA Micro which is a SICK fork with adjustable travel from 120mm to 165..
My SX is sitting at 32.2lbs with downhill cranks. If i put my Hone cranks on there it will be under 32 lbs.
I'll post pics as soon as I find my camera.

Last two dudes, what do you plan to use these bikes for? If you use it for trail riding as well as jumping/slalom stuff, I would love to know how it handles trails. A couple of people have chimed on on that aspect but that is what I would do 75% of the time so more input is appreciated.

I'm going to use it for my everyday trail bike. I like the fact that the stays are so short for the twisty turns. I do jump but there isn't many jumps in my area. I will prob. limit my drops to about 5-6 ft. I have a feeling this bike will feel like my Azonic Steelhead hardtail bike except with 4.2 in of travel in the rear.
I'm not a spinning climber in fact I hate to climb these days. With the family getting bigger and having less time my fitness just sucks so climbing effeciency isn't a concern. When the hills turn steep and fast or technical is where I wake up and shine.
I'll let you know when I get my first ride in how it feels all around. So far the street test felt great. Snappy turning, manuels easy and the front fork feels great even at 165mm. I'll prob drop the fork travel for the climbs though.
I am putting on the Envy Double E2 ring system on the front instead of a front derailler. Basically being able to run a granny and a middle chainring without a derailler. You manually shift it over when you need it. I want to try this or maybe the Hammerschmidt system. We'll see.

Here is mine 2010 SX Trail I. Not the greatest bike to climb up hill with. Down hill its just point and go. A confidence booster for sure.

I just took mine (the silver SX slalom) on a 12 mile XC loop last night. I put on my Gravity Dropper and a 11-34t cassette and it did fairly well all things considered. BB is a bit low for sure so you really have to time the pedal strokes in the rocks. It makes it all up on the downhills. The bike just rips. Loves to come off the ground and corners like nothing else. Pumped.
