Electronic Gear-Shifting System
upElectronic front derailleur (Shimano Di2) An electronic gear-shifting system is a method of changing gears on a bicycle, which enables riders to shift with electronic switches instead of using conventional control levers and mechanical cables. The switches are connected by wire or wirelessly to a battery pack and to a small electric motor that drives the derailleur, switching the chain from cog to cog. An electronic system can switch gears faster and, because the system does not use Bowden cables and can calibrate itself, it may require less maintenance.

Relay
A relay Electromechanical relay schematic showing a control coil, four pairs of normally open and one pair of normally closed contacts An automotive-style miniature relay with the dust cover taken off A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof. Relays are used where it is necessary to control a circuit by an independent low-power signal, or where several circuits must be controlled by one signal. Relays were first used in long-distance telegraph circuits as signal repeaters: they refresh the signal coming in from one circuit by transmitting it on another circuit. Relays were used extensively in telephone exchanges and early computers to perform logical operations. The traditional form of a relay uses an electromagnet to c ...

Team Columbia High Road
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 follow ...

Tour Of California
The Tour of California (officially sponsored as the Amgen Tour of California) was an annual professional road bicycle racing, road cycling stage race on the UCI World Tour and USA Cycling Professional Tour that ran from 2006 to 2019.

Road Bicycle
The term road bicycle is used to describe bicycles built for traveling at speed on paved roads. Some sources use the term to mean racing bicycle. Other sources specifically exclude racing bicycles from the definition, using the term to mean a bicycle of a similar style but built more for endurance and less the fast bursts of speed desired in a racing bicycle; as such, they usually have more gear combinations and fewer hi-tech racing features. Certain of these bicycles have been referred to as 'sportive' bicycles to distinguish them from racing bicycles. Compared to other styles of bicycle, road bicycles share common features: * The tires are narrow, high-pressure ( or higher), and smooth to decrease rolling resistance * The handlebars are bent ("dropped") to allow the rider position to be leaned forward and downward, which reduces the forward vertical cross sectional area and thus highly reduces the air resistance * They usually use derailleur gears; however, single-speed ...

1997 Tour De France
The 1997 Tour de France was the 84th edition of the Tour de France and took place from 5 to 27 July. Jan Ullrich's victory margin of 9:09 was the largest margin of victory since Laurent Fignon won the 1984 Tour de France by 10:32. Since 1997 no rider has had this convincing of a win with the closest margin to Ullrich's victory being Vincenzo Nibali winning the 2014 Tour de France with a gap of 7:39. Ullrich's simultaneous victories in both the general classification and the young riders' classification marked the first time the same rider had won both categories in the same Tour since Laurent Fignon in 1983. The points classification was won by Ullrich's teammate Erik Zabel, for the second time, and their team also won the team classification. The mountains classification was won by Richard Virenque for the fourth time. Teams 198 riders in 22 teams commenced the 1997 Tour de France. 139 riders finished.
