The first bicycle wheels of a chariot drawn by horses, wood with a metal rim strip bicycle, very hard and very bad comfortable to ride. Then a man called Dunlop (Scottish) invented the pneumatic tire, this with Macadam (another Scot) inventing the tar road surface much more comfortable cycle.
The rim bicycle, like the bicycle frame has not changed much in the design of its tower still and always will be. From the first wooden rims, alloy steel Others then and now, if you can afford it, carbon. Of all bicycle parts the bicycle rim can make a big difference in how your bike handles. First, the edge weight affects the sprint and climbing, the weight is low, an effort long, flat, weight is not as important as when you get the wheels of weight can help keep moving. The shape of the rim can be important as well, a flat edge is the best for climbing as aerodynamics are not as important on a hill, a section depth, Aero, RIM will help cut the air, but in a cross wind could cause handling problems.
Materials Bicycle Wheels
The different materials used for rims are very important too, steel is heavy and if damaged can be difficult to bend into shape, but because its so strong that it is very difficult to meet the first place and steel is cheaper than all other subjects. Alloy is probably the most popular rim can be done in any shape and profile, flat or Aero, but not too deep, because then weighed too much, the deeper section rims are of a alloy braking section nearest the tire which is mounted on a carbon deep section for lightness and aerodynamics and a very beautiful bike basket. Like most of things if money is not a problem, you can go for the best, would be an all carbon rim, strong and very light, but there are some problems with these tires, first place that did not stop so well in humid conditions and must use special brake blocks for carbon and can be costly, so the rim is perfectly round and free of bulges in the wall of the rim as this will make braking quite erratic, carbon is a difficult material to work and should stay that way.
Type edge to consider
There are two types of tire to consider and this depends on what type of tire you want to use first are hoses are stuck in the rim of the bicycle, cost more and are difficult to repair after a puncture, but for racing they feel and wonderful ride. pneumatic tires have made great progress recently and are about as good as the guts of performance and are easily repairable and more reasonably priced. Most manufacturers make all styles in both systems.
So should I buy? It is no easy answer, because there are so many choices, has spent years in local bike shop, choose the centers, radios and rims you wanted and he would build the wheels, but now most rim makers also manufacture own sets of wheels, Mavic, Shimano and Campagnolo are probably the most popular websites to see that everything good again, there are other brands and if you go to your local store search magazines cycle or bicycle, you'll find. There are many to choose form, but they are all year round.
