What is the best materials that is out there to use for bicyle rims!? |
question; is there any material that is very strong, very light, and the wight for an bicycle rims, i ahve four question thta i need help for the bicylce rims, i ned a lot of people to answer these questions. 1: what is the best materials to use for bicycle rims, that is very lights and speed, but safe out there 2: what si the differents between,Magnesium-alloy, AL-loy, ALumiun and plactis what do you think is the best for the bicycle rims. 3: what are all the size the bicycle rism comes in and what is the weights of the rims too! on all type of bicycle that is out there! 4: what is the best hub that is out there and why, and what do you perfure HUB or bearings ? please help out! 1) There has been some research going on with magnesium alloy now that may prove successful for rims. The material is magnesium AZ80-8. Currently, I think the best material for a rim is aluminum regarding weight versus strength. 2) Magnesium alloy is usually between 94% and 98% magnesium with other metals mixed in to enhance strength and stiffness. Since this material is so new to the bicycle industry most of these mixtures are industry secrets. Aluminum alloy, again, is a mix of metals consisting of mostly aluminum. AL-loy and ALumin are both aluminum alloys. There are some rims made of nylon but these tend to be heavier and less reliable than their metal counterparts. 3) 12", 16", 18", 20", 22", 24", 26", 700c, 27", 29". 700C rims are actually quite a bit smaller than 27" (contrary to an answer above) but the OUTSIDE diameter of the TIRE is pretty close to 27" while the OUTSIDE diameter of a 27" TIRE is close to 28"... 27" and 700C tires are NOT interchangable but the innertubes are. Rim weights are completely dependent on the way that they are made and would take up a hundred pages or more to lay out every conceivable rim size and weight. 4) There are many excellent hubs out there, but if I had to choose a single hub my choice would be the hubs made by either Hi-E, Phil Wood, or Weyless. They are all hard to find and usually very expensive but put most every other modern hub to shame when it comes to performance. Hubs hold the bearings, you can't have a hub without bearings. Source(s): 27 years in the industry 1) Aluminum is a very popular material, it is used on my ksyrium ES's. Carbon fiber is lighter, stiffer, and can be molded into more extreme wind-cheating shapes. However, it is less strong in the event of a crash. (TDF this year-dog). Titanium is a light, stiff, and strong material. More reliable, too. Both carbon and titanium are very expensive. 2) Carbon fiber is the best material for racing, then magnesium, then titanium, then the other materials you mentioned. The materials you mentioned don't necessarily make a better rim than the other, it depends on how well the rim is made. 3) Modern racing bicycles....700c Most mountain bikes.........26 inches Kid mountain bikes .........20 inch BMX.............................. inch weights.........http://weightweenies.starbike.com/listin... 4) The hub contains the bearings inside.......My favorite is the Roval wheel with the STAR hub. Or the rear hub of the Powertap 2.4 SL (it measures power output). bicycle wheels make good bicycle wheels tried and tested MAVIC has it 1. carbon is good, but not as strong. racers use it, but can replace wheels anytime they want... i stick to aluminum as it's strong, pliable (ti tends to be brittle) and light enough to be fast. 2. magnesium is too soft, which is why 'mag wheels' for cars are made from aluminum now days. 3. older road bikes have 27 or 28 inch tires. now most have 700 c (so close to a 27 that either tire will or tube will fit the rim) , but some bikes for smaller people and nearly all time trial bikes use a 600 c tire. mountain bikes use 26 inch tires, except for bikes for small people which may use a 24, or a couple of Gary Fisher bikes which use a 29. extra weight, but smoother ride over rough stuff. all other tire sizes (in the US and Canada) are for kids so you don't really need to worry about them. 4. i like sealed hubs, BUT if something goes wrong you have to replace the entire hub instead of just bearings. as for brands of either wheels or hubs, picking one vs the other is just personal preferences. it's like having to choose between a Trek, Giant, Cannondale or Orbea. there is no wrong choice, just personal preference. (in non carbon frames, Cannondales are the only ones made in the US just for the record) lead....with steel spokes! |
