Aero Bicycle Wheels

The first bicycle wheels from a cart pulled by horses, wooden with a metal strip bicycle rim, very hard and very uncomfortable to ride. Then a man called Dunlop (Scottish) invented the pneumatic tire, this with Macadam (another Scot) inventing the surface of the tar road bike is much more comfortable.

The bicycle rim, like the bicycle frame has not changed much in design, it still round and always will be. From the first wooden rims, the other made of steel, then alloy 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 weight of your rim affects your sprinting and climbing, the weight will slow you down for a long, flat effort the weight is not as important as when you get the wheels rolling the weight can help keep them going. The shape of the rim can be important also, a flat rim is best for climbing as aerodynamics are not so important on a hill, a deep section, Aero, RIM help you cut through the air, but in a cross wind could cause you handling problems.

Wheels Bicycle Materials

The different materials used for rims are very important too, steel is heavy and if damaged can be difficult to fold into shape, but because he is so strong that it is quite difficult to bend first place and steel is cheaper than all other subjects. Alloy is probably the most popular rim, it can be done in any shape and profile, flat or Aero, but not too deep because it would be too heavy, the deepest section rims are alloy braking section nearest the tire which is then mounted on a carbon deep section for lightness and aerodynamics and a very beautiful looking bicycle rim. As with most things if money is no problem, you can go for the best, it would be an all carbon rim, strong and very light, but there are some problems with these rims, first they do not brake so well in wet conditions and you must use special brake blocks for carbon and they can be expensive, so the rim is perfectly round and no bomb in the wall of the rim as this will make braking quite erratic, carbon is a difficult material to work and must be treated well.

Types of rim to Consider

There are two types of rim to consider and this depends on what type of tire you want to use, first there are the hoses are stuck on the rim of bike is more expensive and difficult to repair after a puncture, but for racing they feel and fit perfectly. Tire tires have made great progress recently and are almost as good as tubular for performance and are easily repairable and more reasonably priced. Most manufacturers make all styles in both systems.

So who should I buy? Not an easy answer, because there are so many choices, you've gone years at your local bike shop, choose which hubs, spokes and rims you wanted and he would build your wheels, but now most rim makers also make their own wheel sets, Mavic, Shimano and Campanology are probably the best known, check their websites for all their new goodies, there are other brands and if you go to your local cycle shop or look in the magazines, you will find. There are many to choose form, but they are all round.
