Air Resistance

Air resistance, also known as drag, is the force that opposes the motion of an object through the air. The air resistance depends on the shape, size, speed, and density of the object and the air. The more air resistance, the more energy is required to overcome it and maintain or increase the speed. Air … Read more

Aerodynamic Advantages

The aerodynamic advantages of a bicycle or a cyclist are the benefits of reducing the air resistance or drag that slows them down. The less drag, the faster and more efficient the cyclist can ride.  Aerodynamic advantages can be achieved by using different shapes, materials, and positions that affect how the air flows around the … Read more

Aerobic Threshold

Aerobic threshold is the intensity of exercise at which the body switches from mainly using fat to mostly carbohydrates as a fuel source. The aerobic threshold is usually expressed as a percentage of the maximum heart rate (HRmax) or the maximum oxygen uptake (VO2max). Depending on the individual and the sport, the aerobic threshold is … Read more

Aerobic Capacity

Aerobic capacity measures the maximum amount of oxygen a person can use during intense exercise. Aerobic capacity is also known as VO2 max, which stands for the volume of oxygen uptake per minute, adjusted to the body weight. VO2 max is measured in ml/kg/min. Aerobic capacity is influenced by age, gender, genetics, training, and altitude. … Read more

Aero Seatpost

An aero seatpost is a type of bicycle seatpost with a streamlined shape and profile intended to reduce aerodynamic drag and improve the rider’s speed and efficiency. The aero seatpost was introduced in the 1990s, as part of the development of aero road bikes and triathlon bikes. Aero seatposts are usually carbon fiber and have … Read more

Aero Position

An aero position is a riding posture that minimizes the cyclist’s frontal area and air resistance, allowing them to achieve higher speeds and save energy. An aero position typically involves bending the elbows and lowering the torso while holding the handlebars in the drops or on the aero bars. An aero position requires a proper … Read more

Aero Helmet

An aero helmet is a bicycle helmet designed to reduce aerodynamic drag and improve the rider’s speed and efficiency. Aero helmets typically have a smooth and elongated shape, with few or no vents and a tail that extends behind the head. Aero helmets are mainly used by time trialists and triathletes, who prioritize aerodynamics over … Read more

Aero Handlebars

Aero handlebars are bicycle handlebars designed to reduce aerodynamic drag and improve the rider’s performance. Aero handlebars typically have a flat or wing-shaped top section and may also have extensions or armrests that allow the rider to adopt a more aerodynamic position. Road cyclists, triathletes, and time trialists commonly use Aero handlebars. The term aero … Read more

Aero Gains

Aero gains are the speed and performance improvements resulting from reducing the aerodynamic drag of a cyclist and their bike. The term aero gains comes from combining the words aero and gains. Aero gains can be achieved by: Aero gains are measured by the amount of power or time saved at a given speed or … Read more

Aero Frame

An aero frame is a bike’s main structural component with an aerodynamic shape that reduces drag. The term aero frame comes from combining the words aero and frame. Aero frames typically have features such as: Aero frames are used by cyclists who want to go faster on flat or rolling terrain, such as time trialists, … Read more
