    The XX1 kit that I posted before couldn't come home with me. My LBS sponsors our race team, and couldn't sell shop inventory for grassroots pricing. Those items have to come from our team order. So...I'll just have to wait 3-4 weeks for my XX1 stuff. I'm in no hurry though.
    Looks like a nice start! I see you went with the SID XX ... out of curiosity did you look at the SID RCT3 at all? RCT doesn't have the remote lockout, but is a bit lighter with the 3 compression mode set up. I'd love to try the RCT before buying one, but sounds like a nice set up, similar to the Fox CTD suspensions?

    Will do! I'm usually a big fan of the Specialized Henge, but was finally able to get my hands on the Ergon. I'm really looking forward to trying it out. Their grips, gloves, and packs are awesome...so my hopes are high for the saddle.

    Nice build plan. Congrats of the purchase.

    Just ordered same RDO gear from OO. Are there different versions on this frame?

    I was going to use Nokon cables and a Rotor 4630 PF30 BB.

    Anyone here with experience on installing the Rotor 4630 BB correctly (prep, grease, carbon paste, loctite, etc). I have read a lot and spoke to everyone in the industry. There seems to be no real concensus and the LBS's just do what they think seems right.

    I think there might be two versions of the Air 9 RDO frame; one with a drain hole in the BB, and one without. I didn't realize this until I got my frame and someone on here asked about the hole. Mine has one.

    I don't have any experience with the Rotor BB. I used the Truvativ PF30 ceramic with this build, and if your BB is like that one, you wouldn't used anything since it's pressed in.

    Hi guys,
    I'm about to pull the trigger on getting a size large Air 9 RDO.
    Does anyone have an accurate weight for the large frame set?
    I've also got another question is the SID WC dual air 29er fork (non XX) a RCT3 model?

    Thx
    Dave

    Thanks for the reply. That's what I was hoping for in the 1200gr range.
    Know just wondering about the fork, maybe I,ll check out the fork area to see if that info is available.
    Thx

    Showed up at my LBS for our weekly ride yesterday...and they had my XX1 kit waiting on me! I pulled out my spare XX cassette for a side-by-side comparison with the XX1 cassette. Just a little bit of a difference...😳

    Not the best shot, but it's starting to look like a bike. Still need to order brakes and wheels.

    Currently weighs in at 10.2 lbs on my Park Scale.Winter Project - Niner Air 9 RDO-imageuploadedbytapatalk1358113857.402196.jpg

    What brakes you going with? I've been doing a LOT of reading on different brakes and based on everything I've seen and read, Shimano is heads and shoulders above the others ... and that includes XTR, XT, and even SLX level!

    Yep! They're SRAM XX1 cranks. I'm going with Magura MT-8's for brakes. I've been running them on my RIP 9 for the past year and really like them! Pricey, but well worth it.

    Oh, nice. How do the Mt-8 compare to XT/XTR?

    I have a set of XT's on my SIR 9. They're nice, but honestly, I prefer my MT-8's. The XT's have good power and modulation, but I feel like I have more control with the Magura's. The feel/shape of the levers with the MT-8's seem to work better for me as well.

    Don't get me wrong...the XT's are great brakes, and I would recommend them in a heart beat! I'm just a big fan of Magura!

    Chris,
    You pretty happy with your set up for hanging bikes vertically on the garage wall? I have to organize my garage first, but I intend to hang my bikes (5-6) vertically with rear tire off the ground. I was thinking of mounting a 2x6 horizontally (top and bottom) for tires to rest on (and save drywall), then simply using heavy duty rubber-covered hooks. I also have a fat bike to hang and not sure that would work with hooks like you have? Your set up looks nice and simple to mount though.

    The setup works great! However, I'm out of room. I'm gonna sell my son's old Trek here soon since he's outgrown it and moved on. That'll give me space for one more (the Air 9 RDO)...until this summer when I pick up a second CX bike.

    Those hooks will not fit a fat bike. However what you don't see behind me in this picture, is my fat bike hanging from the ceiling over (and in front of) my workbench. I used two more (rubber-coated) hooks and hang my Pug by the stem and nose of the saddle. It adds a nice touch to my "shop" and keeps the bike out of the way.

    Winter project is complete!

    Here is what the final build looks like:

    FRAME: Niner Air 9 RDO
    FORK: Rock Shox SiD XX
    RIMS: Stan's No Tubes ZTR Crest 29er
    HUBS: DT Swiss 240s
    TIRES: Continental X-King 2.2
    SHIFTERS: SRAM XX1
    FRONT DERAILLEUR: N/A
    REAR DERAILLEUR: SRAM XX1
    CRANKS: SRAM XX1
    BOTTOM BRACKET: Truvativ PF30 Ceramic
    CASSETTE: SRAM XX1
    CHAIN: SRAM XX1
    DERAILLUER CABLE: Jagwire Ripcord
    PEDALS: Shimano XT
    BRAKES: Magura MT-8
    BRAKE ROTORS: Magura Storm SL
    HANDLEBAR: Niner Flat Top 9 RDO
    STEM: Niner RDO
    GRIPS: Ergon GA1 EVO
    SADDLE: Ergon SM3 Carbon Pro
    SEAT POST: Niner RDO
    BOTTLE CAGES: Bontrager RL

    The final weight came out to 20 lbs, 9 oz.

    I took it out for a 25 mile spin yesterday, to break it in a little. Holy crap, this thing is fast! Scary fast, when compared to
    my RIP 9! The XX1 drivetrain is smooth and precise, and completely silent! I'm running my XX1 in a 32Tx10-42 configuration,
    and didn't miss my 26/39x11-36 2x10 at all. Let me get a few more rides in though, before I completely write-off my 2x10.

    Here are a couple of pics. I'll post more, with a little more review, once I get some more rides in.

    Any chance you could post a photo of clearance between the chainstay an chainring. I want to build a Air 9 with the xx1 but I think the 32T chainring will be too small. Any Better options for 1x cranksets with better clearance?

    Here you go! Kinda hard to tell in the photo, but there's about 1.5-2mm of clearance.

    As for other cranks, I don't believe there are any other options for cranks for XX1 at this time. However, at the NAHBS this weekend, I saw one or two bikes using different cranks with XX1 rings.

Either of the Q factors will work I just warn folks on narrow Q factors and mountain bikes that heel strike can be an issue if they have any abnormality in their pedal stroke."

    I will be running the wide Q factor with a 30T chainring.
    Now that you've got a few rides in, any updates on the wide vs narrow Q-factor? I plan to go with the 168Q on my Air9 RDO, but thought I'd check in and see how you feel with the wider Q ...

    I actually ended up going with the narrow Q factor, and it seems to be working just fine. I've only gotten two rides (~40 miles) in on it though. As soon as I got the bike finished up, our weather went to crap. I'm hoping to get it back out this weekend!

    What made you switch to the 156Q?

    Feel free to make fun of me, but I didn't notice that they were the 156Q until I was checking the bike over after my second ride. I just never noticed, even with it written right there on the crank arms. I had requested the 168Q version, but my LBS must've made a mistake when they placed the order. To be honest though, they feel great, with no heel strikes, etc...so I'm gonna roll with it!

    Just checked my alloy Jet9 with X9 cranks, and it's ~142.875mm from inside of l/h crank arm to inside of r/h crank arm. According to SRAM specs, the XX1 is:

    168Q = 141mm

    156Q = 129mm

    I've always felt comfortable on my Jet9, but I like the idea of more pedal strike clearance with a narrower Q ... decisions, decisions!?

    Great thread. I picked up a Med Air 9 RDO frame and I should have it in the next day or so.

    I'd love to go with the xx1 but due to $$ I'm getting roval wheels for my ride and using 2x10 I already have. Stoked!!

    I'm wondering about seatpost length, niner specs 400mm but I already have a thomson setback, and was thinking about that or an exotic carbon or easton.

    Any thoughts?
    Thanks

    I'd get a carbon post with setback if you need it and for the added flex. A couple nice ones -

    Syntace Hiflex. It's designed to flex a little.

    Niner has their own RDO which would match your frame.

    Thanks, I'll look into the Syntace

    I meant to ask if a 350mm post would be too short, I don't need the setback I just happen to have it.

    Hmmm, you'll have to try it and see. Sometimes there's a minimum insertion mark recommendation.

    I've been meaning to get a "review" of my build up here for quite a while, but I got sidetracked.

    Here is what the final build came out to:

    FRAME: Niner Air 9 RDO
    FORK: Rock Shox SID XX
    RIMS: Stan's No Tubes ZTR Crest 29er
    HUBS: DT Swiss 240s
    TIRES: Continental X-King
    SHIFTERS: SRAM XX1
    REAR DERAILLEUR: SRAM XX1
    CRANKS: SRAM XX1
    BOTTOM BRACKET: Truvativ PF30 Ceramic
    CASSETTE: SRAM XX1
    CHAIN: SRAM XX1
    PEDALS: Shimano XT
    BRAKES: Magura MT-8
    BRAKE ROTORS: Magura Storm SL
    HANDLEBAR: Niner Flat Top 9 RDO
    STEM: Niner RDO
    HEADSET: KSA (came with the frame)
    GRIPS: Ergon GA1 EVO
    SADDLE: Ergon SM3 Carbon Pro
    SEAT POST: Niner RDO

    Weight (with pedals, cages, and seat bag): 20.4 lbs

    First off, wow...WOW! This thing is fast! I've been riding a R.I.P. 9 for the past year, and the (obvious) differences are noticeable right away...mainly the lack of effort required to build up speed. I almost died on my first ride, because I was on a section of trail where I usually hammer it on the R.I.P., but with the same effort, I had built up an insane amount of speed. More than I was used too on that section!

    Frame: The Air 9 RDO frame is awesome, and I can't really think of anything to complain about. If I were forced to find something to whine about, it'd be the rear brake mount. While it works just fine, there's not a lot of space to adjust the rearmost caliper bolt. My medium frame weighed in at 2.5 lbs.

    Fork: The Rock Shox SiD XX is sweet, it's lightweight and simple, and does its job. I wasn't sure how I'd like the new graphics, but once I saw them in person, I really like them. One thing to note, is the remote lockout. I have three XX forks with the X-Loc remote, and while it works great, it MUST be bled before use. All three of my forks required it in order to get the full travel. Maybe this is because I live at 7100 feet. Not sure. Read the instructions on this, because while the process is simple, there are a lot of steps. Something to also keep in mind, is that when the lockout system fails, the fork will be locked out.

    Wheels: I went with Stan's NoTubes ZTR Crest rims and had them laced to DT Swiss 240s hubs. I've used these hubs on my R.I.P. for the past year without one issue. They, along with the Stan's rims, are great products! This is my first crack at the Crest rims (I run Arch's on my other two Niner's), and the seem fine so far. I was a little concerned how they would hold up on the rocks, but so far, so good.

    Tires (sponsor disclaimer): I've been eyeballing the Continental X-King for quite a while, but for some reason, never tried them out. Our team picked Continental up as a sponsor, so since we got a great price on them, I decided to give the 2.2, tubeless-ready offering a shot! I will say that these were probably the easiest tubeless tires I've ever set up. They took a little work to get onto the rim, but the bead set with less than 35 psi and has held ever since. As for grip, they seem to do just fine on hard-pack, stone/rocks, and slightly loose tread. However, while not a show-stopper, they do require a little extra attention in the really loose stuff.

    Drivetrain: What can I say about SRAM XX1 that hasn't already been said? One word; awesome! I am running the stock setup, 32x10-42, and honestly, I don't feel like I miss my 2x10 at all (I run XO 39/26x11-36 on my R.I.P.). The shifting is smooth and precise, and like I'm sure you've read in other reviews, it's dead silent. Setup was easy and straightforward. Two words of advice though; follow the instructions for setting the chain length, especially if you are running it on a full suspension and get your derailleur hanger straightened. Do that, and you'll be golden!

    Brakes: I've been running Magura MT8's on my R.I.P. 9 for the past year, so they were the obvious choice for my Air 9 RDO. These have got to be the best (BEST) brakes I have ever used, and Magura's customer service is second-to-none in the industry. I've used other systems from Shimano and Avid, and have never felt the modulation and control that I get from my Magura's. After I got about 25 miles on the bike, I found out that the MT8's on both my Air 9 RDO and R.I.P. 9 were affected by the recall. I immediately sent the brakes off, and in just under 3 weeks, I was up and riding again! Magura even included four sets of fresh pads! Again...customer service!

    Niner Bits: While they make great 29er's, Niner also does a kicka$$ job with their components! I went with their RDO bar, stem, and seat post, and there's not a lot to say other than they do their job. They're lightweight and match the frame perfectly. I do get a slight flex from the seat post, as well as the frame and wheels, which does provide a little bit of relief on rough trails.

    Ergon Bits (sponsor disclaimer): I picked up Ergon as an individual sponsor this year, so going with the SM3 Pro Carbon was a no-brainer in my opinion. I've used Specialized saddles on my other two MTB's and CX bike for the past couple of years, and love them! However, Ergon has definitely changed my perspective! The SM3 Pro Carbon (while slightly pricey) is a great product. The longest ride I've gotten in on it so far, is about 45 miles, and I haven't had any issues; no numbness, no chafing, no sore butt. I also use their GA1 Evo grips and HX2 gloves, which are a great combo! The gloves fit perfect and hold up really well to abuse, and the grips, while slightly tacky, work like a champ...for well...grips! I also switch to GX1 grips from time to time. I'm trying to figure out which ones I want to use for endurance racing. I'm also looking forward to trying the new SR3 road saddle when it comes out this summer!

    Well...that's it! I've only got a ~250 miles on the bike right now, but so far, I'm really happy with it! So much, that I'm pretty sure Chris Sugai thought that I was going to hug him when I met him at the NAHBS in February and babbled on about how much I loved Niner bikes!

    Let me know if you have any questions!

    I couldn't wait any longer so I threw some old tires with tubes on, but it's pretty much finished. At least it's rideable. I'm hoping to loose a few pounds going tubeless and cutting down the hydraulic lines and bars but its a rocket ship as is!!

    Looks fantastic. About the chainstay/-ring issue and XX1: Have anyone tried a 34T/36T on a Air Carbon? Im too afraid 32T will be to small, even with a 10 back. I run XTR 40/28 on my Air Carbon today with no issues.

    I can't speak to the Air 9 Carbon, but on the Air 9 RDO, there is no chance of running anything larger than a 32T with XX1. There is just over a mm of clearance between the ring and stay.

    According to the Niner Encyclopedia, the max you can run on the Air 9 Carbon is a 32T as well. I would assume that Niner has checked it out, and that this is accurate.

    The Air 9 Carbon looks to have the same clearance as the RDO, I was thinking S-work cranks might have a different chain-line but it seem they are the same. I think the only way to go single chainring with the bigger rings will be to run the 104 bdc spider with a 34 or 36 tooth ring and a guide. Or maybe one of these, 104 BCD Chainrings | wolftoothcycling.com I've been meaning to call and talk to them about it.

    Nice write-up and beautiful bike. If I ever decide to upgrade my frame, the A9C RDO is my frame of choice over an S-Works frame.

    Was hoping you could explain the crankset options.

    Do they make a GXP BB compatible with our Air 9 RDO's or are we forced to go with the BB30/PF30 option or does a GXP fit a PF30 BB? All this BB crap confuses me

    No, you can use the GXP crank but you will need to run an adaptor.

    My wife Air9 RDO is running a GXP crank with This adaptor

    Wiggle | SRAM PressFit 30 to BSA Adapter | Bottom Brackets

    & a standard GXP bottom bracket.

    A standard GXP BB wont fit the Air 9 RDO frame right?
