Singlespeed & Fixed Gear - weight of disk wheel

how much does a disk like a zipp or others weigh. and whats the difference between that and a regular spoke one?

heavier then a comparably priced carbon rimmed /about the same as a lightweight training wheel/lighter then what most people ride around on

so less than a basic wheel.

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

thanks that kinda helped i wanna try to build a disk n wanna see if its gunna be too heavy

build a disk? you work with carbon fiber? you like disaster?

pssssst. It's not rocket science.

zipps are arround 900 grams

big wind and sail

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.

glad someone gets it.

you should probably learn how to stfu before you say something

haha

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

yeah it only needs to be perfectly round

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.

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?

haha yes! i like you guys.

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 ****?

sounds easy!

when did they start making surfboards out of CF? maybe i missed something but aren't they basically wood, styrofoam and fiberglass? with occasional plastic and metal bits to attach fins and leashes and whatnot?

they do. they make skimboards out of cf too.

Just make a disk cover. Any first attempt is going to be a peice of **** one way or another. If you must pust some cf on it for bling when it's spinning noone will know the difference and it will be easier to fix when you realize what a monumentally stupid idea riding around on a disk is.

Disk wheels are useful only in non-wind conditions: the track or short, flat time trial courses. And only if you plan on riding flat out. In city traffic, they would be worse than useless, a heavy anchor to drag from one intersection to the next.

In a time trial in the Coor's Classic back in the 80's, they used disk wheels on the FRONT, too. Dangerous. I've never seen that done since.

i ride a disc wheel on my roadbike on the street even on windy days. if ur that light that the wind is knocking u over because of ur disc u shouldnt be riding. wind+disc+cityriding is not dangerous. that is a myth get a disc and ride it in the street thats the only way you'll know

too expensive to ride on the streets, with no possibility of locking them up.

have locking axle skewers got an old cheap one still true

can you say resin swirls?! then make me a 5'5" fish. thanx.

That is the idiocy of the week! Congratulations!
Why on earth shouldn't light people be riding? All the best hill climbers are light... Pantani shouldn't have been riding or what?

I'm struggling in crosswinds w/ a normal mid rim... with a disk, I'd be flying, not riding.

i kinda want to make one just for the purpose of making one. n for the large surface to paint on. and ken, my friends dad is the man when it comes to making fishes. hanel surfboards. n yeah you can get a crazy swirl in the glass if you want.

They still do for indoor kilo events.

Whatever man. Chicks love disc wheels.
