A track bicycle or track bike is a form of fixed-gear bicycle optimized for racing at a velodrome or at an outdoor track. Some road racing and club cyclists use a fixed-gear bicycle for training during the winter months, generally using a relatively low gear ratio, believed to help develop a good pedalling style. [5]
Freestyle fixed gear is stunt riding on a fixie. It is an extreme sport where the stunts share elements from BMX, artistic cycling, dirt jumping, and trials. The flat ground style of tricks, similar to artistic cycling, is called Trick-Track or Tarck. Street and park riding, that is more similar to BMX, is generally called FGFS (Fixed Gear ...
In sports, backspin or underspin refers to the reverse rotation of a ball, in relation to the ball's trajectory, that is imparted on the ball by a slice or chop shot. Backspin generates an upward force that lifts the ball (see Magnus effect). [1] While a normal hit bounces well forward as well as up, backspin shots bounce higher and less forward.
Hop-up [1] is the backspin put on airsoft pellets and BBs to increase their range via the Magnus effect. Hop-up devices apply backspin to the projectile reducing the air pressure on its top side. This causes the plastic pellet to fall less over a given distance than it would without the spin applied, extending the effective range of the weapon ...
Backspin refers to a sports ball, such as a tennis ball, that is rotating in a reverse direction from its trajectory. Backspin or Back spin may refer to: BackSpin, a classic hip-hop radio station on Sirius XM Radio; Back Spin, a novel by Harlan Coben; Back spinning, the act of manually manipulating a vinyl record backwards during playback
Usually, the sound of a backspin is a shrill, reversed version of the audio being bypassed. Since the sound easily stands out against other forms of music or ambient noise due to its uniqueness, it is usually muted by creative use of a DJ mixer .
In airsoft, a system known as hop-up is used to create a backspin on a fired BB, which greatly increases its range, using the Magnus effect in a similar manner as in golf. In baseball, pitchers often impart different spins on the ball, causing it to curve in the desired direction due to the Magnus effect.
Backspin Is where the bottom half of the ball is rotating away from the player, and is imparted by striking the base of the ball with a downward movement. [2] At the professional level, backspin is usually used defensively in order to keep the ball low. [3] Backspin is commonly employed in service because it is harder to produce an offensive ...
