    Help me trim down this bike..

    Is 12Kg doable with this bike?

    Frame: Titus El Guapo 2009 - small (3.3Kg)
    Fork: Fox F36 FIT 2010 (2.1Kg)
    Wheelset: Hope Pro 2 w/ Mavic 819 Disc UST (20mm front/ QR rear) (1.85 Kg including Titanium skewer for rear)
    Crankset: 2009 XTR triple ring (770g)
    Rear dee: 2009 XTR long cage - non shadow, rapid rise (198g)
    Front dee: XT M771 dual pull (158g)
    Brakes/Shifter:2009 XTR dual control w/ Goodridge hose (approx. 1.1Kg)
    Rotor: RT76 180mm-front, RT76 160mm-rear (158g+138g ->299g)
    Pedal: Exustar PB525 (330g)
    Chain: XTR/Duraace CN117 (295g)
    Headset: FSA Gravity 1 (150g)
    Stem: Thomson X4 70mm (157g)
    Seatpost: Thomson Elite 27.2 + X-Lite shim 27.2->30.9 (220g+10g->230g)
    Handlebar: Crank Brother Cobalt Carbon 15mm risex680mm length (160g)
    Grips: Crank Brothers Cobalt foam grips (65g)
    Tires: Continental Mountain King 2.4 UST (700g/each->1.4Kg)
    Saddle: WTB Devo SLT carbon (205g)
    Cassette: 2009 XTR 9-speed,11-32(221g)
    Total about: 12.988Kg

    Thinking of a cheap solution by doing a Ghetto tubeless (putting a non tubeless tires+sealant), could shave about 200g. Any other solutions without breaking the bank?

    I want to concentrate on the rotational weight because that is where its most noticeable.
    A friend suggest going ZTR Flows instead of the 819 UST. Also plan on changing the rotors to a lighter one, like the Formula Rotors.

    Maybe you might get more response in the WW forum?

    Im using the flows now and i dont really like them. Its been about 4 months since i had that rim and there are multiple dents on them.
    I dont ride very hard. The 38psi max limit is the thing i hate the most.
    The mechanic in my LBS said its okay to go over the limit but over time it will not be good for the rims as they will crack.
    Im light at 50kilos but i do pinch even at 40psi so 38psi is not a good pressure for me. I tried tubeless but the dent in the rim does let air leak out.

    Sorry to hijack.
    I remember from somewhere that the ztr flow will start to show fatigue after 1 year or so of riding. Can someone enlighten me please?

    dont think you can do ghetto tubless. you would need regular rims not ust. seems like a pretty light build already, you could save some weight going to 1x9 but you have dual control so... maybe save a tiny bit going 2x9 with a light bash.

    With my math 12.988 KG = 28.6 Lbs and looking at your current build on a 6" (El Guapo) frame it's really good. To knock off some weight I would look at the tire choice, your wheels are a solid build. Knock your tires down to a 2,25 up front and a 2.1 in the rear and you could shave some grams off. Just an idea

    I'd dip it in a tank of titanium as that metal (or element #22 if you're my High School science teacher) is a bit lighter than aluminum (element #Lucky 13).

    Covering up all that heavy aluminum (13) with titanium (22) should shed about a pound off a standard frame. Dip the entire bike in Ti (22) and you could shave 3-4 lbs.

    It's a semi-pro technique. Try and keep it under your e-hat.
