Sulle origini ho i miei dubbi: se davvero la mtb fosse nata per affrontare le discese non avrebbe i rapporti che ha;
No no, qui hai torto e la nascita della Mtb non è una opinione, essa è nata in origine per scendere dai monti. Non è una evoluzione della Bdc, non è nata per pedalare nello sconnesso ma per scendere dallo sconnesso.

Riding bicycles off-road goes back to the beginning of cycling itself. Road racing cyclists have long used
cyclo-cross as a means of keeping fit during the winter, eventually becoming a sport in its own right with the first world championship in 1950. The French Velo Cross Club Parisien (VCCP) comprised about twenty-one young cyclists from the outskirts of Paris, who between 1951 and 1956 developed a sport that was remarkably akin to present-day mountain biking.

UK [2]
However the mountain bike has its origins in the modified heavy
cruiser bicycles used for freewheeling down mountain trails in
Marin County,
California, U.S.A. in the mid-late 1970s. At the time, there was no such thing as a mountain bike. The earliest ancestors of modern mountain bikes were based around frames from cruiser bicycles such as those made by
Schwinn. The Schwinn Excelsior was the frame of choice due to its geometry. Riders used balloon tired cruisers and later modified them with gears and
motocross style handlebars. They were called Klunkers. The term would also be used as a verb since mountain biking was not yet in use. They would race down mountain fireroads causing the hub brake to burn the grease inside, requiring the riders to repack the bearings. These were called "
Repack Races" and triggered the first innovations in mountain bike technology as well as the initial interest of the public. The sport originated in the U.S. state of California, on
Marin county's famous mountain,
Mount Tamalpais.

It was not until the late
1970s and early
1980s that
road bicycle companies started to manufacture mountain bicycles using high-tech lightweight materials.
Joe Breeze is normally credited with introducing the first purpose-built mountain bike in 1978. Tom Ritchey then went on to make frames for a company called
MountainBikes which was a partnership between
Gary Fisher,
Charlie Kelley and
Tom Ritchey. Tom Ritchey with his skills in frame building also built the original bikes. The company's 3 partners ran into rough times and finally fell apart at the 1983 trade show[
citation needed]. The designs were basically road bicycle frames (with heavier tubing and different geometry) with a wider frame and fork to allow for a wider tire. The handlebars were also different in that they were a straight, transverse-mounted handlebar, rather than the dropped, curved handlebars that are typically installed on road racing bicycles. Also, some of the parts on early production mountain bicycles were taken from the
BMX bicycle. The first mass-produced mountain bikes were produced by
Specialized in 1983 and were copies of Tom Ritchey's frames, but they were not fillet-brazed, and were made in Japan. They were configured with
15 gears.
