Best Answer: Street BMX's generally have a rear brake for slowing down when necessary. If this brake is used with a gyro (attached to the headset) then you are still able to bar spin. If a gyro is not used then a clean bar spin will not be possible without twisting the cables. Source(s): Experience.
Mechanism of Gas and Flatulence. Flatulence is a voluntary or involuntary expulsion of gas through the anus commonly referred to as passing gas or âfartingâ. Gas produced by the breakdown of food within the gastrointestinal tract may cause bloating and discomfort which is relieved upon passing flatus (âfartâ). Digestion is a physical and chemical process that produces byproducts, including gas that is passed out as flatus.
Prevalence, Causes and Treatment. One of the the commonest cause of bloating is food intolerance-or the inability to fully digest certain foods. Incomplete digestive processing produces unexpected gases in the intestine-creating painful pressure, and making the abdomen balloon outwards-stomach bloating. A major cause of stomach bloating is Gluten intolerance. 2  Another major cause of bloating is Dairy intolerance-including lactose intolerance. 3  Also-Fructose sensitivity causes stomach bloating. 4  Other causes of bloating are Nightshade Vegetables and Yeast Sensitivity.
