The Facts You Need To Be Knowledgeable Of About Bicycle Rims
On the bicycle wheel, one of the most important parts is the bicycle rim. It’s not the whole wheel as people often believe but the rim is the metal circle holding the tube and the tire. Each wheel of the wheel set consists of several spokes which are used to connect the rim to the main hub (i.e. the center of the wheel consisting of the axle and the bearings).
Types of Rim
Rims come in various size and shapes depending upon the underlying tire. If the traditional tubular tires (these have inner tube sewn into the tire allowing the tire to be inflated without being mounted on a rim) are being employed. the tire needs to be glued to the rim. They provide excellent speed and is often the preferred choice when it comes to racing even though they’re difficult to maintain and are expensive. There’s another set of tires called the clincher tires and they enclose an inner tube to hole pressurized air. Easily repaired, these tires’ performance is at par with the tubular tires. Most manufacturers produce rim fittings for both sets since they’re widely used.
Building a Bicycle Rim
In the beginning. wooden rims were used. which were later replaced with rims made of steel. However, if the rim gets damaged it’s difficult to mold it back and it’s also very heavy. These were later replaced by alloyed rims (including aluminum). Alloyed rims can be molded in any profile. but not too deep. as that will increase the weight too much. To the bicycle rim, these will provide lightless and beauty. Hitting the market is the latest trend: the carbon fiber rim. These are very light and quite strong. but then they hurt the pocket a lot more. The carbon fiber rims don’t brake well in damp situations. Thus. special brakes that can block carbon are required and these are again expensive. The carbon rims can work if the rim is perfectly circular with no bulging.
