    Air 9 RDO "True" build weights.

    I've built an RDO at 21.15# with pedals and cage, But am seeing builds under 20# and am wondering how. If your RDO weighs under 22#, please post your build. My only heavier part would be my Fox Talas with CTD remote and my 180 front rotor. Here's my build, and I know there's parts that are barely lighter, but where are you losing 2#?

    *Niner carbon cockpit
    *Roval carbon wheels w/ RR tubeless
    *Full XTR
    *FSA Gravity Light carbon crank.
    *Fox CTD Talas w/ remote
    *Crank Cros Titanium pedals
    *WTB Titanium seat.
    *Jaguar cables.
    *Blackburn carbon cage

    21.15 pounds "real" weight on my Park scale.

    Thats about what mine weighed in at. I had a similar build but with a 1x10 setup running xtr. I wouldn't worry that much about the weight.

    It's all of the little stuff that adds up. Cranks, XTR brakes are nice (but heavy), saddle, bolts, etc. 1x10 setups weigh a lot less than 2x10. Your fork probably weighs a pound more than a SID WC.

    18.7lbs with pedals and a bottle cage:

    Rock Shox Sid WC fork, It's a Specialized 2012 brain fork with some red highlights in the paint.

    Specialized Roval SL carbon wheels
    Maxxis Ikon 2.2 EXC front tire / Specialized S-works Fast Trak 2.0 rear
    KCNC Ti QRs

    Formula Rx brakes with carbon levers
    160mm rotors F/R
    Ti rotor bolts

    Sram XX right shifter
    Sram XX rear der (medium cage)
    Sram XX 11x36 casstte
    Shimano Da7900 chain
    E13 chain guide

    Specialized S-works carbon crank
    34T Gamut ring
    XTR pedals

    Syntace F109 stem 100mm
    Syntace Hiflex seat post
    Niner RDO carbon flat bar (red)
    ESI chunky grips

    Specialized Toupe Pro saddle (white/team colors, with plastic bits on the rear removed)

    Wow! That's light. Your bike is 3 1/2 # lighter. We have the same wheels and my pedals are lighter. I can see an extra pound on the fork and 1/2 pound on the 1X, but where is the other 2#? Nice bike bud.

    Thanks! I love this bike for sure.

    You'd be surprised how a little weight here and there adds up quickly.

    XX cassette is very light, like 100g lighter than your XTR. The cranks are most likely at least 200 grams lighter. Saddle only weighs 135grams. ESI grips are quite light, the KCNC skewers are about 45 grams for the pair. The brakes and rotors are considerably lighter than XTR brakes, probably ~75grams per side (maybe a bit more on the front since you have a 180mm rotor). But, I REALLY like the XTR brakes as well.



    Also, my fork came in at 1500grams with the steerer tube cut. Pretty freaking light.

    Still need to finish a few things like cut the bars and the steerer tube, and add some stans, but right at 21, maybe a bit under.

    - SID XX Maxle Fork (not the WC)
    - SRAM XX Crank, Shifters, Derailleurs (2 years old)
    - KMC X10 Chain
    - SRAM X0 Cassette
    - XTR Pedals
    - XTR Trail Brakes
    - SRAM XX Rotors
    - AC Hubs with Crest rims built by my LBS
    - Ergo GX1 Grips
    - Niner RDO Seatpost and Bars
    - Niner Alloy Stem (going to need to save 15g and get the RDO Stem because it looks better)
    - Fizik Gobi XM Saddle
    - No cages yet

    Thinking the WC Fork, lighter grips, different pedals, Race brakes, XX cassette and lighter saddle could get me close to 20 even but what I have is more bike than I deserve.

    It sure is a good looking bike. I know it will handle well and can't wait to see how the RDO post and new frame feel.

    I was thinking you had to use 4mm housing on the A9RDO and Gore Ride-On was 5mm housing. Mine shifts pretty darn good without but would have liked to put in the Gore if I could have.

    I bought the limited edition and changed the following from stock

    XX crank plus 30 grams
    bb-30 bb saved 80 grams
    XX cassette saved 92 grams
    xx 160mm rotors saved 52 grams
    kmc chain saved 40 grams
    bontrager xxx flat bar saved 46 grams
    bontrager xxx grips saved 60 grams
    bontrager 29-0 tires saved 240 grams
    tubeless with stans saved 180 grams
    fizik carbon railed seat 50 grams


    Mine now weighs 19lbs 7ounces on a park scale with pedals and cages. Like others have said small changes all add up to taking over 2 pounds off from stock.

    How about some weights posted for an XL frame? You little fellers with your itty bitty little bicycles have an unfair advantage when it comes to talking pure weight.

    e13 and MRP both make a XC oriented single ring chain guide with a high seat tube mount that attaches where the front derailuer would go.
