Exempel på derailleur

• Its products ranged from suspension forks to derailleurs.

• Shifter controls are mounted so that the right shifter controls the rear derailleur and the left shifter controls the front derailleur.

• Meeting both these requirements is only possible if the rear derailleur is compatible with the gear range being used on the bike.

• For example, a shaft-drive is usually accompanied by a hub gear, and derailleurs are usually implemented with chain drive.

• These bicycles are without derailleur gears, hub gearing or other methods for varying the gear ratio of the bicycle.

• Chains for small cogsets (e.g. seven-speeds) and other than derailleur-fitted bicycles are more tolerant of these master link dimensions.

• This is the main reason that a single-speed bicycle can be more efficient than a derailleur geared bicycle.

• A hub gear system provides greater ease-of-use and safety than a derailleur system, can provide a wide range of ratios, and requires little maintenance.

• Unlike some traditional 10-speed gears using a derailleur, there is no slippage when changing gear ratios.

• Though they are heavier than comparable derailleur systems, internal-gear hub systems generally last longer and require less maintenance.

• The derailleur enters production, enabling gears to change without removing the wheel.

• The others had derailleur gears for a higher ratio for the sprint.

• Hub gears by design are indexed, but for derailleur systems, indexing was an innovation.

• His victory was controversial as he was the first rider to complete the race using a modern derailleur.

• The rechargeable lithium-ion battery pack supplies power to the derailleur motors, which move the derailleurs via worm gears.
