En un esfuerzo para mejorar el foro, les pido ayuda los compaï¿½eros que practican estas modalides. Necesitamos un FAQ( preguntas frecuentes) para que la gente esta bien informada.

Que necesitamos? unas breves preguntas y sus respuestas no importa el numero. Con la informaciï¿½n mas esencial, que es downhill, que es freeride, donde se practica, que necesitas para practicarlo, las carreras, paginas web con informaciï¿½n, quienes lo pueden hacer, etc.

Me lo pueden enviar por email o pm, y me encargo postearlo y darle sticky & locked. Se le darï¿½ el crï¿½dito a la persona que lo escriba.

Muchas Gracias!

tal ves esta informacion te funciones a lo que alguien te envia datos mas concretos. La tome de Wikipedia.

"Trail" Bikes are a cross between XC bikes and AM bikes. They usually have around 5" (120-140mm) of travel, weigh 25-32 lbs, and have geometries slightly slacker than XC bikes, though not as slack as AM bikes. Examples include The Giant Trance, the Trek Fuel EX series, the Gary Fisher HiFi, and others.

Enduro/all-mountain (AM) bikes bridge the gap between cross-country and freeride bikes, typically weighing between 30 and 35 pounds (14 to 16 kg). These bikes tend to feature greater suspension travel, frequently as much as 6 inches (150 mm) or 7" of front and rear travel, often adjustable on newer mid- and high-end bikes. They are designed to be able to ascend mild-to-moderate inclines and descend steep declines, though their relatively heavy overall weight limits their utility in all-day rides involving steep climbs.

Freeride (FR) mountain bikes are similar to downhill bikes, but with less emphasis on weight and more on strength. Freeride bikes tend to have ample suspension and typically have at least 6 inches (150 mm) of travel. The components are built from stronger, consequently heavier, materials. They can be ridden uphill, but are inefficient and their moderately slack head tube angles make them difficult to maneuver while angled up a hill or traveling at a low speed. They are effective on technical downhill trails. Frame angles are typically steeper than those found in downhill bikes. This enhances maneuverability over and around small objects. Freeride bikes typically range in weight from 30 to 45 pounds (14 to 20 kg). Freeride trails are built using natural terrain features to create stunts such as dropoffs, also known as "hucks", narrow ladder bridges called "North Shores", as well as large ramps built to launch the rider into the air. The most durable freeride bikes are often too heavy and have too much suspension to be ridden uphill as comfortably as other less-sturdy models, although newer, more expensive bikes come with suspension specifically designed to make them easier to ride uphill. It is, however, quite common for freeriders to frequent lift accessed riding terrain, offered at ski resorts during the off season, or simply walk their bikes uphill, rather than riding them.

Downhill (DH) races are time trials events where riders ride courses separately, racing the clock. They can have technical sections like rock gardens as well as jumps and drops. Downhill bikes typically have seven or more inches (178 mm) of suspension travel. They are built with frames that are strong, yet light, which often requires the use of more expensive alloys. In the past few years, lighter downhill bikes have been getting below the 40lbs mark (18 kg). Due to their typically large or high gears, long, plush travel and slack geometry angles, Downhill bikes are ideal only for riding down dedicated downhill trails and race courses. Downhill bikes have the most sag of Mountain Bikes to get ample traction to go fast over bumpy trails. Head Angles are often as slack as 64 degrees.
At ski resorts that have mountain biking in the off-season, riders can get lots of runs in because of chair lifts. Shuttling up to the top of trails is very common as most trails away from ski resorts do not have lift access. When there is no car or truck access to shuttle, riders usually push and/or ride bikes to the top of the trails. Due to the high speed nature of downhill riding most bikes only have one chain ring in the front, a large bash guard and a chain guide, though many racers are now using chain guides without bash guards to drop weight.

downhill for the win.

puedo hablar algo de downhill Wink

los que saben quien soy saben que fue mi modalidad principal. Twisted Evil

para el crosscontry el downhill me ayudo en una forma increible.

primero que no temo a bajar, desarrollas tecnicas para bajar que las incorporas en los single track. hay mucha gente que le da miedito ir rapido por los palos pa no quedarte encajado o algo pero en downhill me ayudo a ignorar el miedo y seguir a la velocidad mas alta que pueda acansar teniendo control de mi bicicleta. tambien aprendi a "pompiar" la bicicleta tecnica que se utiliza en bmx muy util pra el crosscountry.
