Mountain Bike V- brakes
Linear-pull brakes or direct-pull brakes, commonly referred to by Shimano's trademark V-brakes®, are a side-pull version of cantilever brakes and mount on the same frame bosses . However, the arms are longer, with the cable housing attached to one arm and the cable to the other. As the cable pulls against the housing the arms are drawn together. Because the housing enters from vertically above one arm yet force must be transmitted laterally between arms, the flexible housing is extended by a rigid tube with a 90° bend known as the "noodle". The noodle sits in a stirrup attached to the arm. A flexible bellows often covers the exposed cable.
Mountain Bike Chain
A bicycle chain is a roller chain that transfers power from the pedals to the drive-wheel of a bicycle, thus propelling it. Most bicycle chains are made from plain carbon or alloy steel, but some are chrome-plated or stainless steel to prevent rust, or simply for aesthetics.
Mountain Bike Tires
Mountain bike tires are built to withstand punishment and to carry riders through rough terrain. While road bike tires are slim and lightweight, designed to glide over asphalt, mountain bike tires are rough and knobby, made to retain traction over whatever comes their way.
Mountain Bike Gears
The idea behind having all of these gears is to allow the rider to crank the pedals at a constant pace (cadence) no matter what kind of slope the bike is on. You can understand this idea by imagining a bike with just one gear. On this one-gear bike, each time you rotate the pedals one turn, the rear wheel would rotate one turn as well (a 1:1 gear ratio).
Mountain Bike Suspension
Many bikes today have both front and rear suspension systems. The suspension lets the wheels move up and down to absorb small bumps while keeping the tires in contact with the ground for better control. It also helps the rider and bike absorb large shocks when landing jumps.
Mountain Bike Frame
A bicycle frame is the main component of a bicycle, onto which wheels and other components are fitted. The modern and most common frame design for an upright bicycle is based on the safety bicycle, and consists of two triangles, a main triangle and a paired rear triangle. This is known as the diamond frame.
