    Looking to shave some weight - BMC FS02 XC - any options?

    Just placed it on the scales and it tipped it at 26.20 lbs. I know it's not a super lightweight rig but I liked the ride characteristics. I'm now looking at places where I can gain some weight savings.

    Setup:
    Front Fork: Fox 32 Float Performance Series FIT4 w/ Remote
    Rear Fork: Fox Float EVOL Performance Series DPS w/ Remote
    Crank: Power2Max Rotor 3D 1x - 32 tooth
    Cassette: Shimano XT, 11-40T
    Chain: Shimano XT
    RD: Shimano XT Shadow Plus
    RD Shifter: Shimano XT
    Brakes: Shimano XT (160/160mm)
    Handlebars: BMC MFB 02 720mm
    Stem: PRO Vibe Sprinter Stem 90mm
    Saddle: Fizik Arionne
    Wheels: DT Swiss X1700 Spline Two
    Tires: Continental X-King (F) / RaceKing (R), 2.2 - Both are "protection" series that have reinforced sidewalls. Already setup for tubeless.
    Cages: 1 Elite Custom Carbon Bottle cage from PerformanceBike

    Thanks dudes!

    Wheels would be the first thing to look at. Something like DT swiss xr 1501 or Dt 240s's with ztr rims would save 160-200g.

    If you're getting new wheels then go for an XD driver and a X01 cassette. That saves another 140g. That'll increase your range of gears as well. Or go for the xtr cassette 11-40 as that'll save maybe 80g.

    Mt Zoom handlebars are light and doesn't cost a fortune.

    Do you need the protection tires? I use them on my training wheels but race on schwalbes EVO tires. My home terrain is has lots of sharp rocks, but for most races I do there's really no need for the protection tires.

    Dont have a specific budget but I don't want to throw down more than $1k. Looking for simple stuff at first?

    I would prefer to get down to 25 lbs.

    I'm getting a dropper pretty soon which will add +/- 500g depending on what the current post weight is.

    Light-Bicycle wheels - $568 - 230gr savings
    Non-protection tires of same flavor as current - ~$120 - 210gr savings
    Chinese carbon saddle - $30 - 110gr savings

    That should get into the 25s after adding the dropper for under a G.

    I own an Fourstroke FS01 that tips the scale at 22.5# or 10.20 Kg.

    Now, a main difference between mine the two bikes is that the rear triangle of the FS01 is alloy and not carbon. Everybody has mentiones here the big piggies, but also take into consideration grips, bottle cages and rotors. All of them are cheap to replace and can add up a lot of weight.

    Wheels, tires and cassette are your biggest anchors...

    If you have a budget in mind, it will be a lot easier...

    budget is about $1k

    I'm thinking about the grips for sure, definitely don't want to lose my bottle cage because I only have 1 and I use it for water(don't ride with camelback usually).

    Whats up with the rotors haha?

    I know I'm running pretty heavy tires(Conti Protection RaceKings) but I dread flats.

    670g each tire. I've already gone tubeless so that helps.

    Wheels - you can get a nice 1500g or less wheelset and still have budget for

    Rotors - Ashima Ai2, KCNC Razor or maybe Formula
    Grips - Lizard Skins DSP, KCNC foam, Ritchey WCS foam...I use Lizard Skins
    Saddle - there are some good saddles in the sub 200g range...Selle Italia SLR is my choice
    Bottle cage - Blackburn Slick weights 23g, holds the bottle firmly and costs around $15
    SRAM XG 1195 cassette - weights a lot less than the XT you have...maybe 120g...

    Here you have around 1.5#...
