    pretty much every manufacturer will have weights listed on their websites. check http://weightweenies.starbike.com/ to figure out how much your spoke/rim/hub wheels are

    you should probably learn how to spell it before you try and build it.

    Yeah, because if you can't spell you obviously can't build stuff.

    Uh, it's a disk wheel...should be one of the easiest bike parts to make out of CF.

    which if you have the proper tools and technical knowledge is completely possible. the circle is easy to creat e in a shop environment. the elipse? thats close to rocket science. up until the late 80's 3point cnc routers, mills couldnt do elipses, and they could it would take ******** forever.
    im a ****ing idiot. well, im happy to admit it.

    the harder part would be centering the hub with the "blank" so that it spins without any hop or wobble.

    the blank would prolly be styrofoam right?

    iv got friends in the surfboard shaping industry n im pretty sure i could do this with some basic tools. making it light is another thing.

    Hmm the way I was thinking it would be constructed would start as a normal wheel with a deep section, drill holes onto the side of the rim on both side (16 on each side if it's a 32 spoke wheel), and then make the CFRP sheets. Drill holes in the CFRP accordingly, remove spokes, and then rivet on the cfrp.

    i was thinking of

    1. acurately mark out on both sides, the center of the styrofoam square.
    2. using a circle cutting jig on the bangsaw, cut the foam down to 1/2 less dia than 700c(it would have to be an outfeed jig even the largest bandsaws dont have enough space to cut down something thats 700c)
    3. using a bullnose router bit on the routertable cut a half round profile along the outer edge of the foam disc.
    4. using appropriate jigs, tacking methods, glue, etc attach clincher/tubular rim to the outer profile of the disc
    5. carve out hole on disc surface with forstener bit. the hole should be towards the outer diameter for the valve
    6. bore second hole using the center points marked out earlier. this is where the hub will go.
    7. mark a line directly across from the valvestem and hole. mount the hub and disc on truing stand. this is where you might have to possibly add some weight/balast to keep the wheel balanced. (this may or may not be a step)
    9. using a sureform rasp, shape styrofoam disc. the idea is to creat a gradual and natural line from the outerflange of the hub down to the endge of your mounted rim. a hot wire could be used, but some modification to the device might have to occur so as not to create inaccurate or awkward cuts because of the hub body and its relation to the rest of the rim. there is the possiblity of creating your own jig where the known dimensions of the hub body are used to create a device/set up where a truing stand and hot wire are used together to create the desired profile.
    10. finish with 80? grit paper
    11. lay up carbon/kevlar in layers. be sure to minimize overlapping layers so as not to throw the wheel out of balance. be sure to bleed the layers properly

    yadda yadda.
    the hardest part is acuracy. you COULD just lay up some carbon but will it be safe? will it ride like ****?
    im a ****ing idiot. well, im happy to admit it.
