    Take a look at my setup and make recommendations

    My current set-up is as follows:

    2012 15.5" Specialized Stumpjumper EVO 29 HT
    Fork: Fox Float RL Evolution 80mm 1.125" non-tapered
    Brakes/levers: Avid Elixir 7 SLs
    Rotors: 180 f/160 r Alligator Serration rotors
    Pads: Kool-Stop steel-backed organic
    Shifter: Sram X7
    F. der: E.thirteen XCX chainguide
    R. der: Sram X0 short cage
    Tubes: Tubeless w/Roval tape, Roval valves, 2 oz BAMFS/tire
    F. tire: Specialized S-Works Purgatory 29x2.2
    R. tire: Specialized Ground Control 29x2.1
    Seatpost: Niner RDO carbon 27.2x400mm
    Seatpost collar: Specialized
    Seat: Specialized BG Phenom Comp
    BB: SRAM PF30
    Crank: SRAM S1250 33t 170mm
    Pedals: Shimano M520
    Chain: KMC X-10
    Handleba:r Specialized XC Mini-Riser 31.8x720mm
    Grips :Specialized Grappler
    Stem:Specialized XC 75mm 31.8
    Headset: FSA integrated w/carbon spacers
    Cassette: SRAM PG-1030 (X5) 11-36 10-spd
    Wheels: Roval Control 29
    Bottle cage: Specialized Rib Cage
    Computer: Garmin Edge

    Bike weight is 23.9 with winter tires (including a bottle cage, Garmin mount, and Shimano 520s) and 23.3 with summer tires. It’s respectable and durable. I am thinking of trying to get it down into the 22 range. Some items I am considering:

    • Trimming down the excess seatpost – it’s a 400mm and I don’t need it that long (should be able to loose 50mm of it and maintain the min. 100mm insertion length)
    • S-Works Prowess carbon bar (already ordered)
    • Syntace 75mm F109 stem (not sure how much this weighs less than the stock one – will weigh when I replace the bar)
    • SRAM XG-1080 cassette
    • KMC X10SL chain
    • Shimano XTR (980) pedals
    • S-Works carbon crank

    Things I am not ditching for weight savings:
    • Grips – not doing the foam grip thing
    • Narrower bar – I love my 720
    • Eggbeaters – tried them and just don’t love them (even though I want to for the weight savings!)
    • I know I can replace the seat, but I’m not.
    Change cassette gear ratios - I have a 1x10 so a 11-36 is 100% necessary to get some range.

    At some point, I may go to a carbon frame like the S-Works or Niner Air 9 RDO. I may also consider going full-suspension like an Epic. This would be in a few years.

    Thoughts?

    Alternates:
    Ward TI spindles - rated up to 220lb
    - cheaper to put in M540 pedals and resulting weight similar to M980 w/same ti spindle for less cost.

    the 1070 cassette is way more bang for your buck, paid only $52 for mine shipped

    E-13 XCX+ crank at 575g. I find no reason to be concerned on this one - love mine, still overbuilt.

    ^^^ is that the actual weight of my SRAM crank w/single chainring?
    On the cassette - the 1070 looks to weigh nearly what my 1030 does??

    right, from the 1030 to the 1070 there isn't a huge weight loss,
    The 1080 at $140 more trims about 100g and is still a fairly cost effective way to remove rotational mass.

    I figured your crank was in the 900g range (but I may be wrong), and an ideal weight loss candidate.
