Here is a description of the function, features and standards of a dirt MTB derailleur:
Function :
The derailleur on a dirt mountain bike performs the same function as on any other mountain bike: it allows you to change gears by moving the chain from one cog to the other at the rear. This allows the cyclist to adapt the pedaling resistance depending on the terrain and speed. On a dirt mountain bike, the derailleur must be robust and reliable to withstand the jumps, shocks and hard landings characteristic of this discipline.
Features :
1. Robustness:
Dirt MTB derailleurs are designed to be extremely robust to withstand the stresses encountered during jumps, tricks and landings. They are reinforced to withstand repeated impacts without compromising their performance.
2. Chain stability:
As with other mountain biking disciplines, chain stability is important to avoid derailments during jumps and landings. Dirt MTB derailleurs can be equipped with chain stabilizing devices to keep the chain in place even in the most extreme conditions.
3. Simplicity:
Dirt mountain bikes are often equipped with simple drivetrains, with a single chainring at the front and a cassette at the rear. Dirt MTB derailleurs are therefore often simple, no-frills designs designed to operate reliably in extreme conditions without requiring much maintenance.
4. Responsiveness:
Dirt mountain bike derailleurs must be responsive and offer quick shifts to allow riders to perform tricks and maneuvers without being hampered by slow or imprecise shifts.
Standards:
Dirt MTB derailleurs generally follow MTB industry standards for compatibility with cassettes, chains and shifters. This includes standards such as mounting interfaces, maximum yoke clearances, and speed ratios.
In summary, a dirt MTB derailleur must offer robustness, chain stability, simplicity and responsiveness to meet the unique demands of this discipline, while remaining compatible with the other components of the transmission system.
