He set a world speed record in 1999 on snow, descending at 187 km/h (116 mph) at Les Arcs. On 14 September 2007, Stöckl rode an Intense M6 mountainbike down the ski slope of La Parva, Chile, reaching the current record of 210 km/h (130 mph). The top descending speeds have always been obtained on snow.
From a mechanical viewpoint, up to 99% of the mechanical energy delivered by the rider into the pedals is transmitted to the wheels (clean, lubricated new chain at 400 W), although the use of gearing mechanisms reduces this by 1–7% (clean, well-lubricated derailleurs and a straight chainline), 4–12% (chain with 3-speed hubs), or 10–20% (shaft drive with 3-speed hubs).
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 ...
Some cyclists may bike differently in winter, by "slow[ing] down on turns and brak[ing] gradually" in icy conditions. [2] Gaining traction on snow and ice-covered roads can be difficult. [3] Winter cyclists may use bikes with front and rear fenders, [1] metal studded winter tires [4] and flashing LED lights.
In the early days of bicycle racing in the late 1800s, six-day racing on velodromes was popular. Only the original race format is a true ultra-distance cycling race as defined here because it was a simple test of how far an individual cyclist could ride during the six day-long event.
In August of each year, up to six hundred riders take part in the race which centers around a 7.6 mile (12.2 km) climb to the top of New Hampshire's Mount Washington—the highest peak in New England. [1] The Mount Washington Auto Road has an average gradient of 12% and reaches gradients of up to 22%. [1]
Downhill bikes are heavier and stronger than other mountain bikes and feature front and rear suspension with over 8 inches (20 cm) of travel, to glide quickly over rocks and tree roots. In competitive races, a continuous course is defined on each side by a strip of tape.
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.
