Bicycle Wheel
Bicycle Wheel - talk about bicycle wheel - Review of Bicycle Wheel Replace your wheels is one of the most cost effective upgrades you can perform. Your bike will climb, sprint and stop better with a lighter set of wheels.
Typically, there are wheels of 4 main components -. the rims, the hub and the spoke nipple
The rim of the wheel that the tire fit on the rims.
It is a series of small holes to accept the spokes and a larger opening for the tire valve. On expensive wheel spokes, the holes can also brass, around the hole and spread to strengthen load.
On race wheels, will have the side of the rim machined braking surfaces. The braking surface sometimes a groove in which it (a 'wear indicator').
Most modern mountain bike wheels using disk brakes . The disc will be bolted to the hub.
Rim Construction Materials &
Typically, bicycle wheel rims are made of aluminum. During manufacture, the aluminum-rim extruded and then cut into lengths. These lengths are bent into circles and then realize the ends together to join them.
Lighter wheels mean that your bike will accelerate faster and easier hill climbing. Some bikes will be cheaper to use steel rims and hubs. Steel wheels are heavy and wet weather braking can be poor.
top of the range sets of wheels for triathlon and time trials often use carbon fiber in their construction.
hubs
The middle part of the wheel hub. The bearings, to allow the wheel to spin housed in the hub. The axis also passes through the center of the hub. The spokes of the wheel are laced into holes in the hub flanges.
spokes spokes are basically lengths of wire with a thread at one end and a be nd (the "kink") at the other.
The cheapest steel spokes are pure. Stainless steel can also be used to reduce weight.
To reduce weight you spoke spoke on "dull" are. That is, the spoke is thicker at the ends (where most stress happens) and narrower in the middle.
Aerodynamic wheels use flat aero spokes to reduce drag. Flat spokes cut through the air better than round spokes.
The more spokes, the wheel of a bicycle, the stronger (and heavier) the wheel will be. The less spokes of a wheel, which is lighter and more aerodynamic the wheel spoke counts ranging from about 20 (a front wheel suitable for racing) and 48 (a rear wheel suitable for trips with very heavy luggage or a tandem bicycle).
The greater the number of spokes, the spokes should last longer before the break -. Stress is divided among more spokes
spoke lacing pattern
spokes to a wheel provided in a variety of patterns. The most common is the 3-or 4-Cross Cross pattern. This means that each crosses 4 or 4 other between the hub and spokes of the rim.
In a radial-spoked to the spokes do not cross any other - this allows fewer spokes are used, and saves weight. Usually only the front wheels use, is radial and then usually only on high-performance bicycles. A radially spoked wheel is not efficient drive-torque dissipate from the sprocket on the rim.
