Merida Big Seven mountain bike with Schwalbe Racing Ralph 27.5″ tires. 27.5 mountain bikes are mountain bikes which use a large volume tire that is approximately 27.5 inches in diameter, 56 mm wide (ISO 56-584 / 27.5 × 2.25) on an ISO 584 mm rim.
Mountain biking (abbr. MTB) is a sport of riding bicycles off-road, often over rough terrain, usually using specially designed mountain bikes.Mountain bikes share similarities with other bikes but incorporate features designed to enhance durability and performance in rough terrain, such as air or coil-sprung shocks used as suspension, larger and wider wheels and tires, stronger frame materials ...
The 26-inch wheel size initially used in mountain biking has all but died off at the top level of cross-country racing, with 29″ wheels becoming the norm and 650b wheels being used occasionally. 650b wheels are 584 mm diameter wheels, and approximately 27.5″ with a mounted tire, hence their more common name, "27.5 inch wheels."
Four-cross race. Four-cross (4X), also called mountain-cross, not to be confused with fourcross, is a relatively new style of mountain bike racing where four bikers race downhill on a prepared, BMX-like track, simply trying to get down first.
For example, if a fat-bike tire is inflated to 0.5 bar (50 kPa; 7.3 psi) gauge pressure at room temperature 20 °C (68 °F) and then the temperature is decreased to −10 °C (14 °F) (a 9% decrease in absolute temperature), the absolute pressure of 1.5 bar (150 kPa; 22 psi) will be decreased by 9% to 1.35 bar (135 kPa; 19.6 psi), which ...
2020 full suspension mountain bike. A mountain bike (MTB [1]) or mountain bicycle is a bicycle designed for off-road cycling. Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain, which often makes them heavier, more complex and less efficient on smooth surfaces.

The most plausible, although still speculative reason, was an early resemblance of the racing courses for mountain bikes with the cyclo-cross discipline, with a major difference: the mountain bike racing track was significantly longer (a cyclo-cross course has 2.5–3.5 km versus 4+ km for a XC track) and free of artificial obstacles.
