29″ and 26″ mountain bike wheels. 29er rims have an interior diameter of 622 millimetres (24.5 in) [1] and the average 29″ mountain bike tire is (in ISO notation) 59-622 – corresponding to an outside diameter of about 29.15 inches (740 mm). The typical 26″ MTB tire has a rim diameter of 559 millimetres (22.0 in) and an outside tire ...
The combination of a tubular tyre and its tubular rim is lighter than that of a clincher tyre and clincher rim, and will therefore always result in less rotating mass or a stronger construction. [5] Tubulars can also be used over a wider range of tyre pressures from 1.7 to 14 bar (25 to 200 psi), compared to the typical 6-9 bar on a clincher tyre.
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 ...
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 ...
Offering cheap material for experimentation, these clunkers were slowly turned into the modern mountain bike. Wider tires on lighter frames, with multiple gears proved to be a wildly successful combination for mixed terrain and truly rugged single track. [15] Early mountain bike designs still make good mixed terrain vehicles, with slight ...
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.

29ers are mountain bikes that are built to use 700C or ISO 622 mm wheels. 27.5 bikes are mountain bikes that are built to use 650B or ISO 584 mm wheels. Downhill bikes are a specialized type of mountain bike with a very strong frame, altered geometry, and long-travel suspension. They are designed for use only on downhill courses.
