    Osteo, thanks.
    I emailed Niner, I read something about the air 9 carbon not being compatible with the ebb, and they said the bb shell isn't strong enough for it. Guess I'm going with the tensioner.
    Small ring in front makes it easier. Small ring in back makes it harder. That blows my mind.

    oh really? Wow.. I wonder if that is the case with the RDO as well? Looks like I'm sending them a message as well... Thanks for the post, I'm sure this will be helpful info for someone else at some point.

    Did some research on this last month. If your frame doesn't have aluminum in the bb shell, you most likely can't use an ebb.

    Well, I heard from Ralph (Niner Tech support) and he confirms with the RDO as well - the One 9 is the only one that will work correctly with the Biocentric II, may PM some of the guys that have the Air Carbons and see what they are using that are in this thread.

    I asked Ralph his thought so n the Wheels Mfg unit, will see what he says but I'm doubtful. I checked the torque specs to compare and the Wheels unit is 8-10NM, the Biocentric II is 106inch/lbs. Not sure if those are the same... Will see if I can find a conversion online.

    This will suck as I got a smokin deal on a rear wheel if I can't use it...

    Google is your friend... 10NM = 88inch/lbs! Quite a bit less considering... Hmm...

    Ok - Ralph replied with regards to the Wheels Mfg... He said 'no' still clamping forces that the BB is not designed to take...

    One of the problems is that Niner made 2 different bikes and called both of them Air9 Carbon. I have two of the original models and run one SS and one geared. The hole in the frame is large enough for the Biocentric BB and there is an adapter to run geared. I think the new bike with the same name has a smaller hole that is made for a press fit BB. Niner has insisted that the new frame is not capable of being run SS with any kind of adjustable BB. The only way I know to do it would be to get one of those rear hubs that has an eccentric or to use an idler pulley. I think the ROS and the SIR are the only bikes Niner has left that are made for SS.

    Bliss.

    Official Niner Single Speed Thread-img_1464.jpg

    First go around with SS. I love it. Simplicity brings happiness. It's light, fun, and makes old trails new again. My build started with the premise that $$ spent on a great set of carbon wheels will pay larger dividends than the same $$ spend on a super expensive frame. So I found an alum. frame on clearance and went to work. After many hours fretting on pieces and parts here is my build. As you will see, in my opinion the XT level of brakes is the "happy spot" as an additional $200 for Xtr seemed frivolous, and after riding the XTs they performed better than expected. Most importantly I am a "very satisfied" customer of Dave at SpeedDream wheels. The reviews are spot on, he communicates thoroughly prior to building, and then he delivers!

    Weight: 20lbs with xt pedals.
    Niner One Nine frame.
    Niner Carbon Fork
    Nox farlow front- Teocalli rear. (Combined weight with tape: 1595 gms.)
    Industry Nine hubs (must they be "that" noisy - but I love the ability to "ratchet" through the nasty stuff)
    Kent Erikson Ti seat post (with an alum. frame the Ti post seemed like a perfect combo.- and it rides with plenty compliance)
    Niner carbon RDO bar
    Oozy 50 mm stem (did the math- originally concerned 50 mm would be too short - but with the 780 mm bar it feels just right, and climbing is no problem)
    Shimano xt-8000 brakes ( 180 rotor front- 160 rear)
    Sram GX 1400 cranks 170 mm (fits perfect 5-11 tall -minimizes rock strikes- and is very affordable, yet comparable in weight & performance to the other "blingy" cranks )
    Niner EBB 2 paired with sram gxp bottom bracket ( super easy to install - no creaks or slippage- just follow instructions - especially torque measurements!)
    Fizik saddle
    Esi grips
    8 speed Sram master link chain (wide & large - strong - lots of heavy pulling on SS - no problems)
    Chris King 19 tooth rear cog - surly spacer kit
    Ikon 2.35 front - Ikon 2.2 rear.

    Notes: I started with the Ardent 2.4 front // Ikon 2.35 rear. This tire combo. felt Ok, but not great, as I am accustomed the light and responsive 2.2 Ikon on the rear. So I changed to the Ikon 2.35 front//Ikon 2.2 rear. The Farlow's 29 mm id makes the 2.35 plenty cushy and the Teocalli's 26 mm id is a perfect fit for the light and grippy Ikon 2.2. Gearing 32-19. This combo is great for everything but the "steep switch back" type stuff. I will probably get a 21 for the rear to put in my quiver when verticality necessitates. I originally wanted an Absolute Black Oval chainring, but after placing cranks I'm doubtful the 34mm portion of the oval will fit. Boo Hoo , I have plenty to work with for now. Just thought this might assist others in the SS building mode. Happy Trails.

    Nice build you have there... I have the same philosophy about a heavier frame combined with lightweight wheels... (L-B 30mm hookless with DT240s.) AbsoluteBlack 32t oval fits my SIS 9 just barely. I even had to file some teeth a little bit from the inner surface of the ring to make it spin without touching the chainstay slightly. I was worried how it would work under maximum power, but so far I have not noticed any scratch marks.

    I'm running 32 x 18 with 180mm cranks which is perfect for my long legs. The oval chainring helps a lot in the steepest climbs.

    If I were looking for a Niner SS with a tapered head tube and 142x12mm rear, this is what I think the available options are:

    Niner One 9 ($$$$) Lightweight, designed as a race SS, with BioCentric BB.
    Niner Air 9 RDO/ Carbon ($$$) Lightweight, only viable with tensioner or eccentric hub.
    Niner Air 9 Alloy ($) Mid-Weight, Biocentric BB optional.
    Niner SIR 9 ($$) A bit beefy, comes with Biocentric, "Steel is Real".
    Niner ROUS 9 ($) Porcine, with Biocentric EBB, "Downhill Hardtail"

    Am I missing any options here? Anything from prior years? I'm kind of stuck on the idea of supporting the through axel and the tapered head tube after riding the JET 9 for a little while so I'm not too interested in older frames right now.

    I'd love a One 9, but the price just isn't there yet so leaning towards a SIR 9 or Alloy Air right now. The 2 pound gap between the SIR and the One is a pretty big gap though. :|

    Have you seen prices on the One 9 RDO frames lately? Around $1200

    Where? I'd jump on that. The best prices I've seen was around $1800 on "Clearance".

    Seek out a nice 1st gen SIR.9.
    They are supposed to be a bit lighter than the 2nd gen.
    You'd have to prise mine from my cold, dead hands. It's a keeper.
    Nothing I've ridden feels as good.

    You pretty much summed it up there, mate. Very succinct.
    The only thing is I have both a One 9 RDO and a Sir 9 and swap between the two bikes regularly. The 1kg difference between bikes doesn't bother me. Its noticeable but not a big deal. I also have an Air 9 and I'd ride the Sir over that any day of the week as it is more compliant.

    Do you think the SIR is more compliant than the One 9? I've always thought carbon was more compliant than steel. I've never really been able to compare the two personally, just assumption on my part.

    My last single speed lasted me 9 years so the durability and longevity of steel is a big draw.

    Definitely.
    Don't get me wrong, the One 9 RDO is very comfortable and has some incredible controlled flex built into it. The SIR 9 has more flex more compliance.
    How I would describe the difference is the One 9 is a sharp, light, rocketship but surprisingly comfortable, even on long rides.
    The SIR 9 is a comfy, smooth ride which is surprisingly light and sharp.
    Two bikes coming at a similar goal but from opposite sides of the argument.

    Compared to buying an Air 9 alloy @ retail (even with a Jenson coupon) and a Beer EBB, it would have been a tough call to not go with the One 9 RDO at that price, had it been available when I bought mine (Official Niner Single Speed Thread)

    Yeah, it's definitely a great deal. I need to wait until I sell another bike so hopefully it'll last a little longer.

    Finally finished, my cobbled together SS! and I can't believe I waited this long! for a time I debated on SS or a Fat Bike no debate this is awesome!

    No rear brake as yet, the set of brakes came off the wife's bike and the rear is too short as I haven't been on the trails with it yet (still too wet here) it is fine as is.

    I made my own pulley tension device seems to be working fine not that I scored the contact surfaces a bit.

    Before I built it I thought I might sell it as well, easier to sell a complete bike than a frame... nope, she's a keeper for sure!!

    Guess I'll join. Loved my SIR so much I got the ROS. Love the ROS so much I just sold the SIR. Been running everywhere I run my 5" travel bike and love the torture. I have been riding SS for 3 years on and off. Friends got back into it so Figured SET THIS THING UP SS TO JOIN THE FUN! Its a blast even as beef as it is but I like bashing jumping and playing when I can. Only downside is I can't go as fast as I want on the downs, otherwise love it. Never ran 32/20 but figured help me climb (32/19 or 34/19). Its a little to spinny but love it once ya break 15 miles. Summer maybe i'll go 34/20. Running Pike fork 140mm with 4 tokens. 50MM stem Renthal, 10MM Rise carbon lites, Reverb stealth dropper, 175mm cranks. Swapped to Specialized newer seat and under seat bolt in tube SWAT holder which is awesome. Along with all other SWAT tools so no pack needed. Just got my Roval Fattie Traverse SL wheels on and some nobby nics which im loving!

    ^^^ That is a friggin gorgeous ROS! Love that color! A buddy has one that he is building up in the same color, mad jealous!

    Here is my new SIR, just put on the AB 32 and Surly 21 (only option available locally) and I have a 19 and 20 on the way way when the galactic backorder ends. A guy at the shop I picked up the 21 from said that 32x21 is what he runs in the area, so I am stoked to try it tomorrow. Ergon grips are also new, $14.50 or something at Pricepoint couldn't pass that up! The Ritchey Streem saddle has been comfy as well, very surprising.

    My Niner Sir 9 single speed. This is currently my most fun bike and the one I like to ride when solo trail riding. It is really a great ride.

    Nice. Which one do you like best? One of these will probably be my next bike but I just can't decide which.

    Sort of a horses for course thing, but if I had to go with one I think it would easily be the plus version for overall simplicity and fun factor. The only time it's not more fun is when terrain is fast and rocky/brake-check bumpy, the big tire in front doesn't make up for suspension entirely. For probably 90+% of the riding I do it's great though. Unmatched traction in sketchy/loose steep downhill-braking very confidence inspiring. The rigid steering is always tighter than a susser fork as well and the Dirt Wizards hook up amazingly well in the corners. The plus also opens up possible bikepacking opportunities as well.

    Here are my two. The wheels on the ROS will go back to the SIR when my new set for the ROS shows up, and I have a carbon bar and new set of grips for the ROS on the way as well.

    Just finished my ROS 9 build. At 26 pounds, it's a lot heavier than my One 9 RDO rigid SS, but it's a far more capable bike when the trail gets rough

    Little bit lighter than mine! Nice looking build, I updated mine a bit since the photo above, not planning on changing much for a while. New wheels, new bars, new grips. Only thing that I have considered is a dropper, but I am still not sure my riding style would notice a difference.

    Thanks!

    I just almost ordered those same grips yesterday. Looks like a fairly close match in color.

    Only have 1 ride on the ROS 9, and am undecided on the dropper. At times during the ride, it seemed like it was taking away the fun of the simplicity of the singlespeed, rather than adding fun like I've experienced with droppers on geared fs bikes.

    Next ride I plan on using the dropper a little more and also throwing on a set of flat pedals. May also try to find a stem that will allow me to get the bars lower.

    Red Monkey lock ons in green/purple. I dig em!

    I would suggest giving flats a shot. While the old set of crank bros on there now isn't the best, it does add some confidence in really techy rocky stuff. I plan to throw a set of Spank Oozy's on there eventually.

    My First SS

    Originally built my SIR 9 geared with a squishy fork, but soon fell in love with the simplicity of SS. So three months in and love it. Heading to SS World Champs here in Aus later in the year.
    Build is X01 Cranks with Direct Mount Sram 32 ring, running Niner 20t rear. Rigid Niner Carbon Fork, Niner Bars, stem and post. Project 321 SS specific hub on Stans Arch EX rims and Maxxis tan wall Ardent 2.4's, Guide Brakes.

    The frame color I wanted for my SIR... although the silver is great as well. But man, something about a clean, white frame.

    I am trying to track down a single speed insert at the rear drop out for my Air 9 (2012 carbon). Having real trouble here in Australia locating one. LBB sourced one through the distributor here, but it must be for a newer model (apparently this one is very hard to get your hands on too according to the distributor). Perhaps I could butcher a derailleur hanger but that would be a last resort and I don't have a spare. Anyone out there know of a AIR 9 single speed insert collecting dust?

    How did Niner change the 2017 Air 9 RDO BB to make it Biocentric 30 compatible?

    I believe Niner has said "NO" to using an EBB in the most recent Air 9 Carbon /Air 9 Carbon RDO frames that use a BB shell which takes a PF30 press fit bottom bracket.

    However, the new 2017 "Completely Redesigned AIR 9 RDO" description includes the following:
    "...The PF30 can be run standard for the lightest race day power plant option available, but if single speeding is your gig, then no worries. Easily install the patented Niner BioCentric 30 bottom bracket cups to give you chain tension and geometry adjustability for your single speed setup....
    The only metal in the AIR 9 RDO is found in the brake caliper mount on the chainstay. "

    Just wondering if anyone can explain how Niner changed the 2017 Air 9 RDO BB to make it Biocentric 30 compatible? Any photos inside the BB shell of a 2017 vs a 2016? For what it's worth, here's a pic of my early version Air9 carbon bb shell lined in aluminum that works with Biocentric II or CYA inserts. Cool that latest RDO seems to again allow either geared or singlespeed on the same frame and wondering how.

    Thanks!

    Niner has eliminated the One 9 RDO SS/geared carbon rocket in favor one carbon HT that can do it all. The 2017 Air 9 RDO can be run geared or SS. The SS option requires the use of Niner's PF30 EBB. I am assuming that the BB shell is beefy carbon to handle the clamping force created by Niner's PF30 EBB.

    Sad to see the One 9 RDO option go away. I run my One 9 RDO SS with a dropper. The new Air 9 RDO runs a 27.2 seatpost, which really limits the dropper options.

    Does anybody still have the 3 Downtube cable clamps and the cable clamps that bolt to the bottom of the bottom bracket for the SIR9? I am also looking for the Niner chainstay protector for this frame. Please let me know
    Thank you

    Hi guys,
    I'm slowing getting together the parts to build my recently purchased SIR9 frame, and I seem to have hit my first hurdle.
    I've installed the EBB in accordance with the Niner video, but when I go to screw in the BB (a shimano XT MT800) the non-drive side doesn't seem to want to go. It goes in a couple of turns but then gets really difficult (I need to use my BB tool). The drive side goes in all the way without difficulty, but before I put some weight behind the BB tool I just wanted to ask your opinion. I have inspected the threads on both the BB and the EBB and they look fine.
    Any ideas? Or do I just need to put my back into it?!
    (This is only the second bike I've built, so it could be a simple rookie error!)

    Thanks for the help.
    And I will post pics once it starts looking like a bike!

    So, long story short, the BB is in! Now I just need to wait for my wheels to turn up...

    (I contacted Niner, and was told that new BBs can be a little hard to screw-in the first time around. They told me to ensure the threads weren't taking any damage and that the use of a BB tool is not uncommon (though I shouldn't need to lean on it).)

    Air 9 RDO

    Here's mine:

    I have a Wheel's Mfg. EBB. Fits very snug, I had to use a BB press at first use, now it's more loose. Problem Solvers also makes this EBB and of course Niner has their own version as well. I found mine to be the least expensive...

    I got some spacers from Endless Biking at NC, and the wheels are I9, the bike feels totally awesome!

    I used to have an earlier Carbon Air 9 when they had skewers... the rear wheel tended to become disaligned, not with the new setup though

    Dude. Sweet bike and all that for sure. However you have 10 cent tensioner on a million dollar build. Rennen tensioner. No substitute.

    Bummer. Have you tried reaching out to Niner to see if they'll cover this?

    My problem isnt that niner wont give me a new frame. My problem is the frames they want to give me. Poop. Not SS race bikes. They cut all but the air rdo and that means all new parts. Nothing on my one9 transfers to an air 9 rdo except stem,bars,seat,brakes. The pf30bb cant take cinch, the seatpost is 27.2 i have an expensive rdo post, the rear is boost, and its not designed as a ss race bike. Its a bike that can take ss and even that is questionable because for all these years niner said no ebb in frames without the metal insert, and then suddenly its okay on the new one. Well with niners history of making defective carbon bb layups and stories already coming in of cracked rdos in ss mode i would rather buy used one 9 rdo and have the same bike ive been racing. We fit like wine and cheese. The new rdo is also slacker geo and i want to run the old rdo fork rigid at 470a/c. So ya, theyll give me a frame, if i can get a used one 9 rdo or air 9 rdo cheap enough i can get an rkt or bsb, rlt or something as my replacement im hoping. My intention was never to imply niner wouldnt get me a frame. Some took it that way and started talking gibberish. Not you. It was in the other thread. Its now been 3 weeks and Niner hasnt emailed me back in regards can the regular new air 9 take the ebb. They are messing around with a loyal customer who starts race season on the 18th. With no race bike as we speak. I guarantee if it was a special or a trek or giant and i was putting those brands on the podium and representing the brand for the lbs and in the community and at races my email asking a simple question would be answered. My dealer handles the getting me a new frame part, i was trying to do my due diligence about what i would want when presented with my options.

    Yeah it's an expensive process trying to get parts swapped. I went through a similar process with another bike - might as well buy it all over again. Just picked up a RKT. I'm tinkering with trying to get the RKT setup as a SS but no luck yet.

    What about a yess tensioner?

    I actually just picked up a super cheap procaliber 9.9 so now ill try and get a rkt or jet 9 outta my rdo. If you are familiar with mountain bike radio the show just riding along the guy Kenny on there has his jet9 a ss and has an rkt. Might be worth asking him for advice dialing in your rkt ss.

    Haven't tried a Yess tensioner but it seems to be discontinued. Didn't know about the radio show but thanks for the tip, I've reached out to Kenny!

    I just ordered 2017 air 9 rdo and biocentric 30 . Niner says you can use bio 30 on the (new air 9 rdo boost frame only ) I hope it's going to work out with no issues.

    Just dont ask niner what bolts to use. They told me the wrong ones on their own product. Idiots. Ill find my receipt and edit this post. Pretty sure they are 12mm and Niner told me 16. Which is just unacceptable.

    Not sure, but don't ti bolts stretch more? THis could cause creaking. I was thinking Nitrided; they should stretch less than plain steel and are really hard to rust or corrode.

    ok for some reason i thought these bolts were bigger(longer) than what they were. These are the same size-almost as what mounts my brake caliper. no need to upgrade to titanium for this but ace hardware should have stainless steel i can grab.
