Technic
Selecting the correct gear system is a decisive factor for cycling enjoyment. The ratio between the lowest and highest gears (the overall range) determines the degree of incline that can be ridden and the maximum achievable speed on the plain. The difference between two neighbouring gears (the increment) determines the comfort and ease with which your speed and momentum can be maintained over different terrains.
When the overall range, gear count and the increments conform, riding enjoyment increases as the gear system is effortless and intuitive to use in all situations, including whilst stationary.
The high shifting speed and effortless gear selection through one simple twist of a shifter (regardless of whether the cyclist is stationary) is simply unachievable for a derrailleur system.
