N What Is Mountain Biking? Mountain biking is a sport which consists of riding bicycles off-road, often over rough terrain, using a specially adapted bike. "Bi" means two, and "cycle" means a full circle of revolution so
the contraption with 2 wheels going around was called the
bicycle. Then it was specialised for
mountains and most other terrains. Bicycle Rear Suspension Saddle Suspension F

Frame How Does Your Mountain Bike
Affect Your Performance? Gears & Brakes There Are 5 Main Things How Does The Rider and his Skill Affect
Their Performance Muscular Strength Tyres & Shocks Absorbs and distributes impacts by having a greater surface area. The tyres are 29 inches and have a ''knobbly'' surface so they may roll easily over obstacles. These combined details maximize
the grip on the tyre. Mountain Bikes have 29 gears and
3 sprockets in the front and 9 at the back.
The gears are much smaller compared to a Road Bike. Capillary Brakes are the standard brakes for the everyday bike they normally need to be pressed quite hard in order to get a fairly immediate effect. An interesting thing about them is that there don't operate well under wet or harsh conditions. Disc Brakes are Capillary Brakes to the extreme they have a longer life span, are stronger and far more reactive. Also Disc Breaks work in all weathers. Frames Its all about strength with frames and having the 3 types of strengths. Torsional Durability Impact Shocks or otherwise known as suspension are design to absorb impacts from drops or jumps. By absorbing the impact, it makes the rider more stable. There are only 3 things that affect
the riders skill How long it takes them before
they tire and need to stop
and rest. Natural Skill The skill built up by a person who Mountain Bikes after a certain amount of time. Their Fatigue/Stamina Physical Build The way your body has devoloped overtime.
Eg: Tall, Flexible, Stronge, Short, Fast. The Idal
body structure for a mountain biker is Stronge, Flexible, Fit and lots of Stamina. Mental Strength My Personal Experience Commitment How committed are you to concuring this
obstacle, and improving your fitness and skill. Concentration Concentration is key to Mountain Biking. If you have a low attention span or aren’t able to concentrate on things for long periods of time you could find yourself in a tough situation. Self-Regulation Is the ability to not wastefully consume the small rations you've brought with you. e.g: water, energy drinks, sports bars, etc.
