    Show your SIR 9's!

    And I have to share this picture from yesterday. THIS is why I took off work yesterday!



    My 6 year old on his first day without training wheels! And I was riding my SIR9 SS so it counts in the thread.

    I'm having issues with brake line placement. Where are the lines meant to be placed when using...

    Right Hand = front brake
    Left Hand = rear brake.

    The frame is designed for the opposite. Also, my SLX rear brake line wants to run outside the frame. See pic.

    Suggestions?

    Just picked up last week. Have three rides on it and so far I like it. Very nice ride compared to a scandium one9 I rode last year (only one ride though). Not sure if niner was wanting me to toughen up or not but they shipped a 19t cog instead of the 20. It's working so far but wow, what a crank on the hills! Would like to throw the brakes over a hill and go with some hopes' but that'll be a while.

    thanks Tim and Pro Mountain Outfitters!

    Thanks. Currently the trails I'm riding are flat, frozen, hardpacked sandy singletrack. If I plan to ride someplace with more climbing and technical, use my geared 29 with front suspension. Been running this tire combo for a few years now, this being the 2nd rigid SS I've owned. Thought about trying something different, but figured stick to what I'm used to. The Ardent 2.4 up front running 18-20psi and the carbon fork make the ride real comfortable.

    First mtb and I think I did it right. For what I want to do with it, this fits the bill perfectly. All it took was one test ride...

    Nice looking bike! How do you like it? I've been riding a SiR9 since 2009 in all kinds of set ups, SS, 3x9 and with a Rohloff IGH. Currently it's set up as a SS and its my favorite of the three. Anyway, enjoy your new bike!
    Happy trails!

    Well its only day 1 so I'd be the stereotypical internet expert if I gushed about it just yet. But.... I took it out for a spin with my wife and her brand new bike this afternoon (short ride) then rode it to Bev Mo for beer. Nothing but smiles and giggles, totally in love. Upgraded to the RS SID fork for no other reason than my own vanity; I wanted a better fork without any experience to base that on and I didn't like the look of the white one it came with. I think black would've looked just as good, if not better. Whatever. I can't complain one stinkin' bit with the deal and service I got on this. Can't wait to throw my fly rod into a pack and head miles into the back country...

    Posted the "just born" pics a few pages back, basically just how it came from the shop. It appears I'm inadvertently transforming my XC bike into an all-mountain style ride though. Not sure how to feel about it but it sure is fun!

    Added Enve bar and seatpost (huge difference).
    Replaced the saddle with a WTB Volt cuz the stocker sucked.
    Spank Oozy pedals.
    And just recently I'm trying a 2.5 DHF up front, moving the HR2 to the rear which replaces the 2.35 Ikon. The HR2/Ikon combo is awesome and I might even like it better than the DHF up front but I'm headed for some softer terrain with lots of reportedly wet forest action so I wanted something knobbier out back. That gave me the opportunity to try the DHF. Its frickin humongous. I didn't care for the chunkey monkey up front so we'll see how this goes. Certainly feels solid but this combo is noticeably slower on anything but down. Even then, it doesn't feel like it carries the same momentum. Or maybe I'm just not going fast enough...

    Nice rides, everyone. Anyone using Alfine with the SIR 9? I'm looking to build an ultra-reliable rigid training bike. I do stupid stuff like ride through grassy fields and hunting trails with lots of sticks, but too many steep hills around here to deal with a SS for four-hour rides.

    No ride is too long for a SS. Period. Sorry, the Alfine will not work, they dont make a 142x12 version of it. I think there might be a rohloff option sooner than later but its not on their webpage.

    Is anyone running a 120 on their Sir9? I know it isn't recommended, but curious as to what the experience may be like. (background: I'm coming from a Honzo with a 120 and have the opportunity to get a Sir9 frame cheap) Thanks!

    That is probably a really bad idea. I would think its even worse if you are talking about the original sir9 frame. They make a steel frame that is designed for 120-140mm forks. I feel like its probably more than geometry, the sir9 is probably not designed for that kind of load or riding style

    Here is my new Sir 9 build…Arctic White with matching (sort of) RockShox Sid XX World Cup. Built it as a 1x11 (mostly XX but with X0 shifters) with Thomson stem and post, Ritchey carbon bar, Stans Arch EX rims on hope hubs and Avid Elixr CR brakes.

    This replaces my Motobecane Ti 29er…I am noticing this is (understandably) a bit heavier (~ 25 lbs) but I like it and am hoping the weight penalty will fade as I ride it more (I also replaced my carbon CX bike last year with a Reynolds 853 bike that is now my favorite bike of all time).

    What are other Sir 9's with a 1x setup and suspension fork weighing it at?

    More brains? Like trying make a deal with someone whom you already had a deal with, and then reneged only to blame your wife. Was our arrangement not a fair one? Or did the other buyer offer you more money after I had already paid? Either way honor, honesty, and integrity are apparently to much to ask for when dealing with strangers on the internet.

    Anyone considering or already have completed a 27.5+ conversion? I am thinning of building up a second wheelset to (occasionally) go id-fat with my Sir 9. Would loe to see pics of any other Sir 9's with 27.5+ wheels and would like to know what rim/tire combos work. Cheers

    "sir9+"

    Been running my 1st gen SIR.9 with 27.5+ / 29+ for a while now.
    It's simply great.

    3" Surly Knard on a Velocity Dually (45mm) up front.
    Rear is a 2.8" WTB Trailblaster on a cheap stock rim that comes up about 28-29mm (1.125"). It's a temp measure to see how it worked out). There's plenty of clearance. Both ends running ghetto tubeless, front at about 16psi, rear at about 18psi.

    Was looking at a Velocity Blunt (35mm) for rear but thinking a Dually will work too.

    Ride wise, it's so responsive through tight terrain. Really does suit the bike well. There's quite a few + sized options here in the UK now. We don't see a lot of snow to warrant a full fat for most, but + size seems to be a good compromise. Certainly for the muddy XC routes local to me anyway.

    Will try & add some pics.

    "sir.9+"

    Hope this works...

    **Excuse the odd looking rear, I've not trimmed the split tube used for the ghetto tubeless due to it being a temporary wheel.

    New SIR

    Show your SIR 9's!-imag0953.jpgShow your SIR 9's!-imag0954.jpg

    Took this bad boy on its maiden voyage over the weekend. This is my second SIR 9. I had a gold first gen model a few years back that I traded in for an A9C. I've regretted the decision lately. The A9C is nice.... but there's just something about a good steel frame. Found a good deal on a new SIR 9 frame so I decided to switch back! I moved over most the parts from the A9C to this build.

    Moondust RDO fork (the color combo is growing on me)
    RDO stem/bars
    XO cranks
    XT brakes
    Thomson post
    Selle Italia saddle
    Race Face Turbine wheels
    Rocket Ron/Racing Ralphs

    Comes in at just under 22lbs. Heavier than I thought it would be, but it rides GREAT! Truly a different feel than the A9C.

    SIR Single

    I just picked this SIR a few weekends ago at Niner warehouse sale with the idea of having flat bar bike packing bike.

    Having a blast on it so far on the rigid ss but considering adding a front shock as needed.

    Man, just maybe the best mtb I've owned in 25 years of mtb rides.

    - med Sir frame with LB/Dragon carbon rims on I9 hubs with cx-ray spokes
    -XX1 crank and AB oval ring
    -enve bar and stem
    -Thomson post, wtb saddle
    -Ardent 2.4/2.2 tires
    -ck cogs - currently 32/19
    -RS Sid with remote lockout (crummy fork)

    Came off an aluminum hardtail ss and I'm extremely pleased with the feel and ride of this steel frame.

    I've been wanting to build a sir 9 for years. Finally pulled the trigger a few weeks ago.... Man i Love the way this bike rides.Show your SIR 9's!-2015-12-26-16.31.06-1.jpgShow your SIR 9's!-2015-12-26-16.38.06.jpg

    So a couple months back I helped my brother in law purchase a moondust grey sir 9. Completely corrupted me. The stand over. The rider compartment. Good ol' 853. Ended up selling my touring rig, a moots ybb 29er and picking up a white sir9. Reminded me a lot of the Gunnar Rockhound 29er I parted with when I purchased the moots.

    So far- way more tire clearance and the 142 makes it ultra stiff in the rear, which is nice when you elect to run BB7s. Those were my two beefs with the Mootsie (and Gunnar).

    Haven't ridden it excessively to say whether it feels as supple as the Moots, nor would I expect it to- but the feeling of owning blue collar steel again...

    So I built a soma wolverine with the xt 9 and then used the wheels, fork, stem bars and pretty much just scrounged the rest from the parts bin or friends to get the sir9 up and running.

    The compatibility and interchangeability of the 240s hubs is truly remarkable.

    Sir9 frame- medium
    Fox rlc 100mm fork
    Stans arch hoops w/ 240s hubs
    Moots post
    BB7 brake set
    Thomson 90mm stem

    The rest is Johnny Stock and fill in wabi sabi. Will purchase an m8000 grouppo before the touring begins this season.

    Pink grips were my daughter's and are just awesome.

    Stripped, sandblasted and clear coated frame and fork for that utilitarian, toned-down look.

    Originally an arctic white frame, size small with a salsa Cro-moto tapered and Thru-axle fork

    Easton Arc rims, Hope Pro 2 Evo 40T hubs, DT swiss comp spokes, Maxxis Ardent 2.4 tires

    XT M780 groupset modified to a 1x10 setup, raceface 32T narrow-wide chainring, Wolftooth 42T giant cog, Wolftooth 16T cog, Wolftooth GoatLink direct mount replacement for improved shifting and chain wrap

    Niner RDO cockpit, ESI grips, WTB Silverado Team saddle

    Shakedown ride this afternoon and noticed the rear rotor rubbing with the calipers while the frame is flexing during hard climbs. Anyone experience this? Shouldn't the maxle stiffen the rear and avoid such flex?

    Anyone know the weight of the Sir 9, small? I'm on a One 9 Hydroformed right now and thinking about changing to a Sir 9 or a One 9 RDO. I know the Sir 9 is the heaviest of the bunch but just curious about how heavy.

    I know this isn't an exact answer to your question but I have both the current SIR 9 and current One 9 RDO and they are built up identically (same forks, wheels, tyres, bars, brakes drivetrain, saddles, seat post) and there is 1kg difference between the two bikes. Both medium frames.

    Wow. a 2.2 lbs. difference just from the frame? Makes sense...I hear estimates that the SIR is 5 lbs. and the RDO is 2.7 lbs. The hydroformed One 9 is right in the middle at 3.5. Not sure if the extra weight is worth the improved ride quality over the hydroformed.

    Pull the Maxle and check that the axle in the hub isn't broken. Check for play in the freehub. I've broken 2 Hope SS hub axle in the last year. Both have been replaced under warranty and the last has been replaced with a steel axle

    Yeah, its a difference but hey, I ride both the One 9 RDO and the SIR 9 equally. I don't notice the weight persee (only if I am carrying them) its the difference in the steel and the carbon I notice. One 9 is sharper, accelerates quicker but the SIR 9 takes less concentration and can sometimes be more comfortable (and faster as a result) when I'm not completely in the "racer" mindset.

    Thanks, went ahead and checked, and my problem was the maxle wasn't tight enough! There wasn't any play with the hub or the wheel, but when I tried unthreading the maxle the tension of the QR lever wasn't as tight as it should, it came off easily. Re-threaded and re-tightened and made sure the QR was tight enough to leave an imprint on my palm. A quick run through our local trails and no more rubbing.

    Picking it up tonight. Got a great deal on a NOS small SIR 9 in moondust. It was originally going to be a single speed, but decided to sell the JET 9 and go back to a hardtail for the first time in over 13 years.

    The build:
    Small moondust frame
    X-Fusion Slide with 15mm thru
    Chris King Headset
    XT cranks with Absolute Black 34t oval ring
    SRAM GX gripshift and rear derailleur
    Niner aluminum post and bar (710 width)
    Notubes Crests with Kenda Karma 2.2 SCT (holding air for a month with no sealant in them yet)
    Ashima 160R and 180F rotors w/pink highlights
    Older Deore brakes (will eventually upgrade those)
    Sunrace 11spd MX8 11-42 cassette
    Photo has an old, beat up San Marco ERA but will have an old, beat up San Marco Aspide on it when I pick it up while I search for what I want for my next saddle.

    I am looking forward to riding a hardtail again and seeing if I am faster, slower, or no difference on my local trails.

    Reborn/rebuilt after scoring some wheels. Good to have her rolling again after a couple years hanging in the garage.

    Would like to score a suspension for for it though.

    Got mine out on it's maiden trail ride on Saturday. After almost 14 years on full suspension it was definitely different being back on a hardtail.

    I have always wanted a Niner 853 bike, used to be the MCR, but since that was discontinued the SIR has been the only option. Currently looking at a few used MCR's as well as a few SIR's, and started thinking about possibly trying singlespeed. Anyone with an SIR ever convert back and forth? I am curious how much time that takes, not that I plan on doing it daily or anything.

    These things are gorgeous, post more photos!

    Had a SIR9, 80% of the time SS, changed it every two months for a weekend only, fairly easy, took me around 20 minutes (when I had to mess around with the rear derailleur), if not 10 minutes top.

    get it, you wont regret it

    Haven't run mine geared but I ran an Inbred that I used to swap regularly.
    Left the shifter bracket on the bars. Was 1x9, (eventually 1x10), with a front chain guide left on all the time. Easier these days with thick/thin rings obviously. One of the cable guides needed splitting.
    Swap wheel, mount the shifter & mech, slot cable into guides, swap chains.
    Took 10 mins tops.

    But, why on earth would you want to run gears... 😉

    Nice to see some action on this thread...😀

    Honestly, never tried an SS, so I can't yet say whether I like gears more or less than SS. One reason I like the SIR, is if I don't like SS, its just a couple parts shy of a 1x11 (which I want to try as well).

    When you are swapping from geared to SS, you can reuse the shifter cable, correct?

    I'm using a full length outer gear cable attached with zip ties, so it's even easier and faster to change from SS to geared. You never need to adjust it, just put it on or take it off.

    I was using the same shifter-cable-derailleur combo in my previous One9 which was specced for full length outer.

    Well, that is pretty brilliant. Do you have to switch the derailleur hanger? I don't see any reason that the SS wheel would have an issue, but just curious.

    Hoping it all works and I don't NEED to switch, we will have to see how well the setup agrees with the foothills here in Boise.

    I switch the hanger together with the derailleur, so I just need to open the two tiny screws to remove it...

    Well, I ordered a white medium, and received a white large... and they don't have another one, but they do have a yellow, which I don't really like. So, the shop is going to order the new grey/white for me it looks like. Anyone have any photos of one in the wild?

    New Silver/White SIR

    Apologies for the steerer, had it cut today but am sick and haven't had time nor motivation for a proper photo. I can assure you I will take a better photo, and that it does in fact look WAY better without the periscope.

    Niner SIR, medium, Stan's Rapid wheels, Maxxis Icon 2.35's, XT 8000 crank, XT8000 brakes, Thomson Masterpiece seatpost (stolen from another bike to get enough post), Ritchey WCS Stream saddle (jury is still out, only 10 miles on it so far), Ritchey alloy bar and stem. I plan to try some sort of alt bar like the Answer 20/20 or Origin 8 UL8, not sure which, but I know I want carbon since its a rigid.

    After I test the waters on gearing, I plan to get an absolute black oval ring, but I want to determine what size and what cog I will want to go with it, I am thinking 32/19, but we will see.

    What dropper are you running in your SIR? I am almost convinced to go the dropper route and have been looking at the PNW Rainier and X-Fusion Hilo.

    Its a 27.2 KS LEV, but I can't say that I'd recommend it. It has a very slow return rate and sometimes gets stuck down requiring a 'butt bump' to get it to return. This was after KS rebuilt it under warranty. I'm now rocking a Niner RDO post on the SIR 9.

    I have a 30.9 Thomson dropper on my bigger bike which I love, and I think they also make a 27.2 version, but its $$$$.

    I don't have any pictures unfortunately and I've since removed the post, but basically I ran the cable down the downtube just as you would for a front derailleur, and then up the NDS side of the seattube. I used a zip tie to anchor it right at the base of the seattube above the bottom bracket. Worked pretty good.

    Decided to put the dropper back on and give it another try. Applied some Slick Honey and operation is a bit smoother, but still slower than I like return. Gotta say a dropper on a fully rigid single speed is a lot of fun, feels like a giant BMX bike

    Cable clamps

    Do you still have the 3 Downtube cable clamps and the cable clamps that bolts to the bottom of the bottom bracket for the SIR9? I am also looking for the chainstay protector.
    Thank you
    tuned

    Honestly, not much to tell right now. We've had a bit of snow and cold, and then warm and rain... meaning our trails are muddy and unrideable right now. Clearance is good with the tires, you can see some pictures here:

    For instance, the rear clearance is still fine with the "2.8" TrailBlazer on a Blunt 35 rim:

    I am contemplating getting a SIR 9 to be used for bikepacking. I wanted to get some opinions of actual owners before pulling the trigger. Do you guys think this would be a good choice? I am planning on riding the Great Divide Route, not racing it just touring it. I found a good deal on a really clean bike but want to make sure it will fit the bill.

    There have been a few do the Tour Divide on SIR.9's.
    Imagine doing it single speed... :-)

    Haven't had a chance to take it out on the trails so I rode it into work this morning. Felt pretty good over the potholes. LOL.

    I told my wife a few weeks ago this this is probably my favorite bike I've ever owned. After working out seat post issues (replaced carbon with a thomson post and clamp) I have had zero issues. Upgrades since last pics include some carbon cranks, xtr brakes and egg beater 3 pedals. I went to a RS reba fork and I am really happy with it. I had a sid on it for a minute but that went on the other sir I bought for my wife (the white on white looks better any way). Any how....

    I've been riding my BNiner a bit more, and I'm really enjoying this wheel size:



    The clearance is generous with a WTB TrailBlazer on the rear:





    No tire rub at all, I could probably go a bit bigger, even.

    I have a Jones Plus (29+), as well a Karate Monkey with a 29+ front/2.4" rear. I think this smaller wheel size has the grip and confidence of the bigger wheels, but turns noticeably better due to the lower inertia of the smaller, lighter wheel. Maybe a sweet spot, for me.

    You did a good job of hiding seatpost cable on that one!

    The snow has melted quickly in Central NH over the past 2 weeks. I took my SIR 9 out on my local trails for the first time this Spring. Put on a new saddle, my "training" wheelset, and new SLX 11-42 cassette. While skiing was good this winter, I really missed riding this thing.

    My SIR 9

    Scored a great deal on a NOS Sir 9 frame. Transferred all the parts from my SJ HT with the sliding dropouts. Such a great bike. I also have a ROS 9. And the difference between them is crazy. ROS great at smashing through stuff, SIR great at threading the needle.
