as a race bike, would you choose the demo 8 or demo 9?

i have a demo eight for starters and its great for racing. the difference between the eight and nine is that the eight has a lower bottom bracket for better cornering in racing. And since the ribcage isnt as beefed up as the nine it is a little lighter. other wise the suspension works the same. and if your looking to buy an eight i got one up for sale.
Gimme your RMX and i'll tells ya
The 8 feels more agile , front feels lower (but it might be the same...) and the rear was easy to throw around,
Riding the 8 realy opened my eyes but the 9 felt like just another bike ,
I am only describing feelings and this can change with sizes and settings...
The 8 is designed to be a race bike where as the 9 is a freeride bike. Just look at the components, ect. The 8 is ~5 pounds lighter because of parts and the lighter frame. I can't see any reason to get the 9 over the 8, especially because the 9 is more money than the 8.
I went with the 9 for several reasons.
I'm a bigger guy, so the extra weight is not noticable. I'm not using it for racing, so it isn't an issue.
I like the extra travel, and feels much more secure with the bolt on axle in the rear vs the qr.
Lots of the big rig manufacturers are going with the 150mm (D9) axle and creates a better chainline from my understanding.
I rode both, and didn't like the low bb of the 8...i hit the pedals which was really annoying. Price wise, I purchased a brand new 04 for much cheaper than a D8 would have cost so it was a score for me.
I have to agree that the weight of the 8 is a plus for racing, but overall my decision to go with the 9 was much better for me. It feels very nimble to me, and having 9 stinking inches is sure nice lol...
Both are great rigs, you just have to decide what you want the bike for..if you are a big guy like me, not doubt you can go either way..both awesome bikes.
I like the 8, but I feel like the chainstays are too short. In a fast, tight, steep berm, I can't pump the 8 nearly as hard as I could pump my old M1. The short chainstays/really steep head angle allow you to set up for a fat pump, but then coming out of the corner and completing the pump just loops you out.
I don't know if the 9 has the same length chainstays or not, but that is something to consider. Also, the steep head tube angle might not be to your liking, but it is an excellent bike. Have fun!
after riding down the largest mountain in the uk, i'm glad i have the demo9.
it took the abuse and laughed, although i wasn't laughing at the 6hr uplift.
...well the 8 wasn't REALLY intended to be a DH race bike, but it was designed with that in mind. It's really more of a double-duty freeride/DH race bike.
If it really was designed for DH race application, then it wouldn't have a 46.5" wheelbase (and that's for a MEDIUM frame) and weigh so much (look at the M3, and the Orange 223/224). Also the suspension design itself is intended for use in big drops.
This isn't to say that the Demo 8 isn't at home on the course racing. I've had mine since Feb. and it's perfect for what I do (DH/FR). I like the fact that the frame is soooo burly and over-built. I can't afford to get a new frame every couple of years, so the tougher it is the better. The construction of the head-tube joint where the box sections join is VERY well reinforced. I was looking a an M3, but felt uneasy about accidentally denting the monocoque forward section of the frame, thereby weakening it.
The Demo 9 is for the big boys out there who need a big bike, or for the hucker who wants to go HUGE. It's geometry is absolutely identical to that of the Demo 8 - look here: http://www.specialized.com/bc/SBCBkModel.jsp?spid=9694 and compare the geometry between the 2. The Demo 9 is probably one of the most well thought out and designed FR bikes out there. Not really great for racing unless you are a big guy and have the muscle to throw this thing around on the course.
Either way - they're both great bikes.
They're aren't dh bikes
Some interesting info here. I was looking at the 8 as a possible race bike for next season (I actually want to get semi-serious about racing next season) so i'm just trying to find out some general info and opinions.
I'm also looking at the Giant DH team
If I do end up getting a new bike, it would be strictly for DH. I'd be keeping my Rocky Mountain RMX for FR and social DH.
I'm waiting for 'the one that goes to eleven'
Why did Specialized leave out the through-axle and 150mm spacing on the demo 8?
What would be interesting to find out is if the Rear triangle of the Demo 9 will fit on the Demo 8.
Anybody have any warranty issues???
lighter weight thats why
man if your getting another bike get a pure race bike not the demo the geo on the demo is **** and your rmx would prolly be just as good for racing.
i would say look into something more like a turner dhr or a cannondale gemini maby even a orange 223 or something exotic like yeti 303 or foes mono if you got the cash. there are endless possibilitys out there besides the demo line which really dosn't shine much when put next to those full bore dh bikes
My buddy just cracked the seat tube on his 9. I'll post pics when I get 'em.
Yeah, All those are nice, I'm just toying with the idea for now, I'm not actually gonna get the bike for months, so i'm just looking around
opinions vary but a friend of mine has a Demo 8 set up for racing and I think it's pretty good ride....the Demo series can hang right in there with all the other brands....D
They can be made to be extremely light, too. The one I'm going to get is going to be around 38 when it's done.
I've figured out the future weight for mine by running some calculations, and even with tubeless (I have a 888RC though...) I'm projecting a target weight between 41.42 and 42.42lbs depending on whether or not I go with a DH40 for next year...
What the hell are you putting on your Demo 8 to make it so light???
...and yeah the Demo 8 can be set up to be an awesome DH race rig, just ask Kyle Strait...
With me, I was going from my old 02' Big Hit w/Big Link to the Demo 8 and the geometry feels second nature to me at this point... The wheelbase is an inch longer than most DH race bikes so it rides super stable at speed... plus, with the shock in the lower mounting hole, the HT angle is a comfy 66deg...
Yeah, sad thing about going lighter...the lighter the more costly. One of the MTBR guys claims to have it down below 40. I think with tubeless, Fox 40 and the new DHX air shock it could easily be close to 38...sweet build built for speed.

Its all about the hydrogen filled frame tubing
demo 8, lighter,lower,faster.
hmm..now I'm thinking I should just keep the one I have for sale....D
It's an awesome bike...
That is some sneaky marketing right thurr
I can't wait to place my frame order this month
seriously...I'm thinking about it....I like my Gemini but it does have swingarm flex that really irratates me at times...D
You won't have ANY flex with a Demo, that's for sure!
haha...guess what I just finished building
well if the demo 8 and demo 9 got into a nasty fight then i'm sure the demo 9 would win by a tiny margin. but this is racing...and bikes don't fight.... so the 8 would probably be a faster bike for an average size person since it will be easier to maneuver. I have an 8 and i love it
Sweet! I've had mine for a few weeks now. It's so fast!
man..the speculation on the Demo 8 is funny. It all came down to 2 goals from what Brandon and Herndon explained to me.
Goal one - get rid of rear end flex. Hence the shock location and redesign
Goal two - One bike for every purpose.
The QR is a bonus of the stiffer rear end and it works. For people wanting 1 bike for everything trail oriented, the Demo 8's seatpost goes way up or way down, you can change a flat trailside without an 8mm (granted yourfront fork will need tools) and it can adjust BB height and even accomadate a 24" wheel without screwing geometry for the big huck wheel crushers out there.
It will work with triple ring, double ring or big ring DH...pretty versatile if it's your only bike...
somebody has been doing some research I see...
that's exactly why I looked into it...for all the reasons you listed...D
I really dislike my Demo. I have a 15" BB (in the low setting! :mumble: ) and run my DH40 at 7". I dont understand why my bb is so high, maybe custom geo? (straits old bike)
Hmm, id love a racier bike, possibly a demo 8... :
...if you have Strait's old Demo 9 (we're talking about the Red one here I'm assuming) ask Kyle if you can talk to his bike mechanic Reg.
The only custom work I know of on that bike is the use of a different colored seatstay (silver), shockstay(black) and S-Link (silver)...that plus the fact that they had to custom fab some shock mounting hardware since this was before DHX's became OEM on the Demo series (2006).
In the lowest setting the BB is 371mm or 14.6"... that isn't too bad.
It's all rider preference I guess.
