Bicycle Trainer
A bicycle trainer, also known as a turbo trainer, is a piece of equipment that makes it possible to ride a bicycle while it remains stationary. They are commonly used to warm up before races, or when riding conditions outside are not favorable. Operation A trainer consists of a frame, a clamp to hold the bicycle securely, a roller that presses up against the rear wheel, and a mechanism that provides resistance when the pedals are turned. In a wind trainer, the roller drives fan blades that create air resistance. These are typically the least expensive and noisiest trainers. Magnetic trainers have magnets and a conducting flywheel operating as an eddy current brake. They are moderately expensive and moderately noisy. Some magnetic trainers have handlebar-mounted control boxes to change the level of resistance during a training session. Fluid trainers use liquid-filled chambers to create resistance. They are the most expensive and quietest trainers. A small number of trainers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The symbol , known in Unicode as hyphen-minus, is the form of hyphen most commonly used in digital documents. On most keyboards, it is the only character that resembles a minus sign or a dash, so it is also used for these. The name ''hyphen-minus'' derives from the original ASCII standard, where it was called ''hyphen (minus)''. The character is referred to as a ''hyphen'', a ''minus sign'', or a ''dash'' according to the context where it is being used. Description In early typewriters and character encodings, a single key/code was almost always used for hyphen, minus, various dashes, and strikethrough, since they all have a similar appearance. The current Unicode Standard specifies distinct characters for several different dashes, an unambiguous minus sign (sometimes called the ''Unicode minus'') at code point U+2212, an unambiguous hyphen (sometimes called the ''Unicode hyphen'') at U+2010, the hyphen-minus at U+002D and a Hyphen#Unicode, variety of other hyphen symbols for v ...

Outline Of Cycling
Cycling, also known as bicycling or biking, is the activity of riding bicycles or other Human-powered transport, human-powered vehicles with Wheel, wheels, for transportation, recreation, exercise, sport, and other purposes. People who engage in cycling are called cyclists, bikers, or bicyclists. They may wear everyday clothing suited to their destination or specialized cycling attire, sometimes carrying an additional set of clothes. Cycling includes not only traditional two-wheeled bicycles but also unicycles, tricycles, quadricycles, and other human-powered transport, human-powered vehicles (HPVs). Some bicycles are equipped with Electric motor, electric motors (e-bikes) or other forms of Motorized bicycle, motor assistance. Cycling can be done individually or with others. Passengers may ride in front,for instance in the box of a cargo bike, sit on a luggage carrier, or use specially designed seats for children or pets.

Bicycle Tire
A bicycle tire is a tire that fits on the Bicycle wheel, wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs, and handcycles, frequently for Wheelchair racing, racing. Bicycle tires provide an important source of Bicycle suspension, suspension, generate the lateral forces necessary for Bicycle and motorcycle dynamics#Balance, balancing and Bicycle and motorcycle dynamics#Turning, turning, and generate the longitudinal forces necessary for Vehicle propulsion, propulsion and Bicycle brake systems, braking. Although the use of a pneumatic tire greatly reduces rolling resistance compared to the use of a rigid wheel or solid tire, the tires are still typically the second largest source, after Drag (physics), wind resistance (air drag), of power consumption on a level road. The modern detachable pneumatic bicycle tire contributed to the popularity and eventual dominance of the safety bicycle. Bicycle tires are also used on unicycles, tricyc ...

Bicycle Rollers
Bicycle rollers are a type of bicycle trainer that make it possible to ride a bicycle indoors without moving forward. However, unlike other types of bicycle trainers, rollers do not attach to the bicycle frame, and the rider must maintain balance on the rollers while training. Bicycle rollers normally consist of three cylinders, drums, or "rollers" (two for the rear wheel and one for the front), on top of which the bicycle rides. A belt connects the middle roller to the front roller, causing the front wheel of the bicycle to spin when the bicycle is pedaled. The spacing of bicycle rollers can usually be adjusted to match the bicycle's wheelbase. Generally, the front roller is adjusted to be slightly ahead of the hub of the front wheel. History Bicycle rollers are nearly as old as the bicycle itself. Mile-a-minute Murphy is pictured riding on them as early as 1901. Riding on rollers Balancing the bicycle without riding off the rollers is an extra challenge for the rider and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cycling Power Meter
A cycling power meter is a device on a bicycle that measures the Power (physics), power output of the rider. Most cycling power meters use strain gauges to measure torque applied, and when combined with angular velocity, calculate power. The technology was adapted to cycling in the late 1980s and was tested in professional bicycle racing i.e.: the prototype Power Pacer (Team Strawberry) and by Greg LeMond with the Schoberer Rad Meßtechnik, SRM device. This type of power meter has been commercially available since 1989. Training using a power meter is increasingly popular. Power meters generally transmit data wirelessly and can be paired to a Cyclocomputer, bike computer, smartphone, or smartwatch. By providing instantaneous feedback to the athlete, and by allowing more precise analysis of rides, power meters can be a useful tool for training. Interfaces Older cycling power meters use a set of wires to transmit power information to a computer mounted on the bicycle; this syst ...

ANT (network)
ANT (originates from Adaptive Network Topology) is a proprietary (but open access) multicast wireless sensor network technology designed and marketed by ANT Wireless (a division of Garmin Canada). It provides personal area networks (PANs), primarily for activity trackers. ANT was introduced by Dynastream Innovations in 2003, followed by the low-power standard ANT+ in 2004, before Dynastream was bought by Garmin in 2006. ANT defines a wireless communications protocol stack that enables hardware operating in the 2.4GHz ISM band to communicate by establishing standard rules for co-existence, data representation, signalling, authentication, and error detection. It is conceptually similar to Bluetooth low energy (BLE), but is oriented towards use with sensors. the ANT website lists almost 200 brands using ANT technology. Samsung and, to a lesser part, Fujitsu, HTC, Kyocera, Nokia and Sharp added native support (without the use of a USB adapter) to their smartphones, with Samsung ...

Cogset
On a bicycle, the cassette or cluster is the set of multiple sprockets that attaches to the hub on the rear wheel. A cogset works with a rear derailleur to provide multiple gear ratios to the rider. Cassettes come in two varieties, freewheels or cassettes, of which cassettes are a newer development. Although cassettes and freewheels perform the same function and look almost the same when installed, they have important mechanical differences and are not interchangeable. Freewheels A freewheel (also known as a block) consists of either a single sprocket or a set of sprockets mounted on a body which contains an internal ratcheting mechanism and mounts on a threaded hub. Threaded rear hubs were available in different thread patterns depending on the country of manufacture, French and British threads being the most common. The British Cycle Engineers Institute (CEI) thread was adopted as the international standard and is now known as British Standard Cycle (BSC). It is a standardi ...

Team BikeExchange, 2021 Paris-Nice
A team is a group of individuals (human or non-human) working together to achieve their goal. As defined by Professor Leigh Thompson of the Kellogg School of Management, " team is a group of people who are interdependent with respect to information, resources, knowledge and skills and who seek to combine their efforts to achieve a common goal". A group does not necessarily constitute a team. Teams normally have members with complementary skills and generate synergy through a coordinated effort which allows each member to maximize their strengths and minimize their weaknesses. Naresh Jain (2009) claims: Team members need to learn how to help one another, help other team members realize their true potential, and create an environment that allows everyone to go beyond their limitations. While academic research on teams and teamwork has grown consistently and has shown a sharp increase over the past recent 40 years, the societal diffusion of teams and teamwork actually follo ...
