    New question here. X-post: Why is my Demo 7 still heavy?

    X-post from specialized forum. So I just weighted my bike yesterday and I was upset to find out that my bike was still 41.87 pounds! I know it is pretty light, but I was hoping to get it to 39, low 40.

    I started with a stock 2007 Demo 7 I and have upgraded, heres the specs.

    Fork: Boxxer Team
    Stem: Sunline direct mount
    Bars: Sunline V1
    Brakes: Juicy 7
    Seat: SDG Ti Fly
    Grips: ODI
    Headset: Cane Creek Double XC flush
    Tires: Kend Nevegal 2.5f 2.35f
    Ti coil
    Pedals: 5050XX
    Chainring: E-13
    Cassette: Sram PG-970 road 12-26
    Chain: Pg991

    I have 823 being laced up to the stock hubs now. Everything else is stock.

    What is wrong with my build? I figured it would be down to low 40 at least by now.

    get lighter pedals and running the 823's tubeless will get you down to that number you want

    You can drop a bit by swapping to some lighter pedals (magnesium) but that won't get you to 40 lbs... It's going to be pricey getting that weight any lower and then you have to think about durability with all the lighter parts. I'd just ride the hell out of it as is, after all it's not a XC ride

    2 pounds is easy....swapping to lighter rims, getting rid of innertubes by running tubeless and swapping pedals will easily drop it 2 pounds

    lighter pedals. you could convert your boxxer to a WC air spring. You could also get some Hope 2 piece rotors, they have an aluminum center hub and they are significantly lighter than steel rotors.

    what seatpost are you running? That could help with about .25 .5 lbs. Lighter pedals for sure. I run Drive Technologies Pro, they're super light, very durable and relatively inexpensive ($65). They would save you close to a pound.

    823 along with tubeless set up will save you some wieght like smt said...

    that was the main upgrade that got my V10 under 40 lbs.

    but the cheap things to upgrade will be pedals, and seatpost.

    the one that will make your bike feel way different, is the rims with tubeless.

    why do you care? ride your bike, weight reduction of 2lbs is WAY over rated unless it is in the wheels.
