    Winter Project - Niner Air 9 RDO

    Brown Santa dropped off the first parts of my winter project yesterday! I'll be building this up over the next few months, and hope to have it on the trail by the first weekend in March!

    The (medium) frame, as most of you already know, is a work of art! I threw it on my (Park Tool) scale last night, and it weighed in a 2.5 pounds. Wow! I knew it was light, but I was honestly expecting it to be little heavier!

    I'll post updates and pics (and probably stupid questions) as I get it built up!

    How can you wait until March? I built my licorice RDO up on Halloween & I've got nearly 400 miles on it now. THE most grin inducing bike I've ever owned. You will love it!

    I'm looking at an Air9 RDO build myself, so I'll have to follow your build and see if I can learn anything Do you already know exact specs you'll go with, or still researching parts?

    Nice looking bike! I'm just taking my time with it...and trying to stay in the green with the boss. I still have two other mountain bikes to ride in the meantime! I can't wait to get it built up though! I demo'd one a few months ago, and couldn't believe how great the ride was. And the acceleration felt like my road bike.

    Yep! Here's how I will be building it up. I've already received the frame, bar, stem, and saddle. The post, fork, and grips are currently on the way. I'll slowly acquire the rest of the parts over the next couple of months.

    FORK: Rock Shox SID XX
    RIMS: Stan's No Tubes ZTR Crest 29er

    Very Nice! What do you expect the weight to come in at ... 20'ish lbs?

    I'm hoping to build a h/t at 22lbs or less (including everything). Still researching bikes and parts, but if I do go with the Air9 RDO frame I've got a few things picked out already:


    FRAME: Niner Air 9 RDO (licorice)
    FORK: Rock Shox SID XX, 15mm maxle (remote lockout)???
    RIMS: Crest, Arch EX, maybe carbon???
    HUBS: Hope Pro II Evo
    TIRE - FRONT: Conti Race King 2.2 ???
    TIRE - REAR: Conti Race King 2.2
    SHIFTERS: SRAM XO/X9 (probably trigger)
    FRONT DERAILLUER: E13 chain guide ???
    REAR DERAILLUER: SRAM XO/X9
    CRANKS: SRAM XO/X9 (1x10 w/ bashguard)
    BOTTOM BRACKET:
    CASSETTE: SRAM XO/X9
    CHAIN: SRAM PC 1091R
    DERAILLUER CABLE: ???
    PEDALS: Shimano XT
    BRAKES: SRAM XO/X9
    HANDLEBAR: Niner RDO
    STEM: Niner RDO
    HEADSET: ???
    GRIPS: ESI Chunky
    SADDLE: WTB Rocket V
    SEAT POST: Niner RDO



    XO or X9 parts will come down to budget vs weight advantage. I currently have a full X9 1x10 setup on my Jet9 and it works great, but I'd really like to go lighter with an Air9 if I can afford it. Still undecided on wheels, and while I'd like to go light here, I don't want to give up too much durability as I do some longer races too. Keep hearing about these "Chinese" carbon wheels and wonder how they compare? For tires I'll probably go with Race Kings but I've also had great luck with Specialized XC tires (FastTrak, Renegade) ... which are especially easy to set up tubeless!

    This build will match most of the kit that I used on my R.I.P. 9, which has been solid, lightweight, and very reliable!

    I don't (personally) know anyone running the Chinese rims, but from what I've read here and there on MTBR, some people seem to like them. Me personally, I MIGHT pick up a set of Roval's once the dust settles on me making it rain for this build. I'll have to see how the Crest's do first before I spend the money though.

    I'm also a big fan of Specialized tires! I run The Captain (F) and Fast Trak (R) on both my RIP 9 and SIR 9. That combo has worked really well for me all along the Front Range here in Colorado! I will likely run that same setup on the Air 9 RDO for everyday use...and swap to the IKON's (or second set of wheels with IKON's mounted) for racing...which has also worked really well for me.

    When I built up my Jet9 in 2010, my first choice for tires were Ikons, but none were available (local or online). Went with the Conti Race Kings and I was pleasantly surprised! Fast rolling and MUCH better traction then I expected with the low-profile treads (especially as a rear tire). Not completely sold on the RK's as front tire though? Captain front with Fast Trak rear is a nice combo, but probably too heavy for racing? I've heard nothing but good about the Renegades too and this year they added 2.3's to the mix, so might try them as a light race tire? So tell me about the Ikons ... how do they compare to a tire like the Fast Trak (front and/or rear)?

    I'm also looking hard at the Crest wheels but I see a lot of posts about them being too flexy? Arch EX would be an easy choice for me, albeit heavier then I prefer for xc racing? I assume the Rovals would be VERY pricey to purchase individually ... not sure I can justify the cost?

    The first piece of the drive train has arrived, a SRAM XX 11-36 cassette. This thing is a work of art.

    Could you please check if the frame has a drain hole at the bottom of the BB.

    The Captain/Fast Trak combo is a little heavy, when compared to the IKON's. I definitely notice the weight difference up front. Maybe a tad heavy for my taste for racing, but a ton of fun for regular riding! I run the Fast Trak backwards, and found that it grips pretty well here on the Front Range. However, the IKON's hook up well too...but do suffer a little in the front, as compared to The Captain. For racing though...IKON's!

    As for wheels, it'll be a little trial and error. I run Arch's on my other bikes, and this will be my first experience with the Crest. I have a buddy (who is slightly heavier) who runs the Crest in the same type events that I race, and he loves them! I guess we'll see how it goes!

    The Rovals are actually reasonably priced ($1700) when compared to other wheels, such as ENVE ($2500), and have a pretty good reputation. I'm definitely gonna give the Stan's a shot first!

    Roval Carbon SL or basic Roval Carbon? Out of curiosity, what do they weigh ... while I'm sure they're much stiffer, wondering how much lighter they are compared to Crest?

    SL'S. They are fast. The weight is published on their site, but i think they are 1400? BTW i also weigh 185 and ride some rough singletrack. New ikon's where i ride lasted one ride. The rivals are strong.

    Good to know about the Rovals. Light, stiff, and durable ... sounds like a real nice upgrade!!

    Still making up a build list and looking at SRAM site to get an idea of price/weight options. Regarding components like shifters and brakes ... is the listed price and weight for a set, or only one of each??

    For example SRAM lists XO brakes at $245 and 315g ... I assume double that for front and rear brakes?

    XO 10 spd shifter lists price for a "pair", but not sure if weight (232g) is for pair or each??

    Chris,
    About the drive train: Can you tell me what Q-factor and crank length you chose?

    I've bought me also an air 9 rdo frame and I want also a sram xx1 drive train, but I'm not sure which q-factor would be the best (regarding clearance whith chainstay).

    Thx for the info!
    Grtz

    When my dealer aksed Niner which q-factor crank they recommended the wider one, 166 I think it is. Don't know if that means the 156 won't work, but that's what they recommended. Could be their safe answer for right now, without a lot of experience with that crank yet.

    I emailed Niner a while back about Air 9 RDO/XX1 compatibility, and here is the response that got:

    "We have been testing the XX1 drive train from SRAM and are finding that we will likely need to put a limitation on the front chainring size of 32 teeth to avoid frame interference. 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.

    Why would you run the 30T after that email?
    The wider Q-factor crank doesn't move the chain line further out, just a larger bend in the crankarm

    I had asked them about which Q factor they recommended, and if the RDO could accommodate the full range of XX1 rings. It looks like either Q factor would work, I prefer the wider...and that there's a chance that the maximum size ring I can run is 32T. I'm going to try the 32T first, but I also have 30T.

    I'm building up a Air9 RDO for my wife & am thinking of going with the XX1 so will have to see what works,

    Depending on your timeline, I can definitely let you know how it comes out. I probably won't be done for a month or so though. Need to wait on the drivetrain to come in. I couldn't bring the one in the pic home. Our team order has to be separate from shop inventory to get the special pricing. Oh well...I can wait!

    I will be running the wide Q factor with a 30T chainring.
    I would think a 30t ring would leave you short of gears for any faster/open sections ... assuming you do some racing?

    I currently run 1x10 w/ 32 ring and 11-36 cassette, and I have never felt the need for more granny, but there are a few occasions I could have used more top end. With the XX1 having a 42 granny cog I would have thought most would go with an even taller ring up front vs smaller ... 34 or bigger? If the XX1 doesn't allow a bigger ring due to frame clearance then I would find 1x10 a better and more versatile setup.

    I do race (endurance events...poorly, mind you), and my rationale is that late in those type events, I'm pretty much in my 26T up front the whole time with my 2x10. I plan to try out the 32T on some of our longer climbs here in COS before jumping to the 30T. If it works out well, I'll probably leave it as-is. However, if I happen to get into the Leadville 100, I can't promise I won't be running that 30T.

    I think you'll find the 32 ring gives you more than enough granny ... especially with a 42 cog out back! If 32x42 doesn't get you up a climb, I'd venture to say it would be faster (and less fatiguing) to get off and walk. During 24 hour races I've found that later in a race I actually look forward to one or two dismounts on steep or longer climbs .... gives a nice mental and physical break from pedaling, and I find helps me stay fresh/faster for the remainder of the lap.

    Due to cost, I'll likely be going with another 1x10 for my Air9 build, but I look forward to hearing how that works out for you!

    Hi having a 30 on the front of the XX1 group gives you about the same top end as having a 35 tooth ring up front on a 36-11 cassette.

    On my Jet9 RDO with XX1 I ran last week with the 32 up front & this week with the 30 & next week I will run it with the 28 & then the following week I will go back to 32, Just to see how they feel.

    At this stage I'm liking the 30 & feel that my be what I use for my main chain ring but we will see.

    That is what is so great about the XX1 you can just choose on the day how you feel.

    I forgot the XX1 went all the way down to a 10 cog vs 11 on most 1x10 setups.

    With that said, it looks to me like the 30t ring w/ 10-42 cassette (XX1) would have the same top end as 33t ring w/ 11-36 cassette (typical 1x10) ...

    30:10 = 3.00
    33:11 = 3.00

    It was early & I was half asleep, I ment to say that with the 32 front ring was like 35 on 36-11

    I figured that was probably a typo or honest mistake on your part. Over the past couple years I've found your feedback to be spot-on for the most part!

    I'm running the SIR single speed, and wanted a super lightweight, geared bike for endurance races. I raced my RIP in the Silver Rush 50 last year, and was really wanting a carbon HT by the end of the race!

    All three of the bikes will get plenty of time in the dirt! All depends on my mood and where I'm riding!

    Very nice! Better watch out though, she might take it from you!

    I am curious to see how it does SS. What does it weigh like this, 19-19.5 lbs?

    Wow it rides really sweet set up with the "Paul Melvin" Feels no different than any other SS. I thought about getting the Air9 Carbon to run the EBB, but it is honestly a totally different bike, and I loved this one so much geared i will just run the melvin and be happy and comfy.

    I have it set up with a 34/20 right now, but will probabaly run a 19 for most AZ Races. Weighed just a hair under 20lbs before I put my Bellini Bell on!

    Chris, You know Jon Pettit (raced on your 4 man at pueblo a couple year ago) he is running XX1 and it is cool. You should dig it.

    Did any of you guys put one of these frames on a scale before you built them up??? I'd be very interested to hear what the real-world weights are coming out as....

    My medium Air 9 RDO frame weighs 2.5 pounds. I was surprised by how light it is.

    Here's the current state of my build. Right now, it's kind of in limbo waiting on the rest of the parts. The bike, as it's built up right now, weighs in at 7 pounds on the dot.

    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.

    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.

    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.

    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 know I've posted these pics before, but wanted to add them here too)

    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

    So if I bought the GXP version of the XX1 crankset could I use a regualr PF30 BB?

    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?
