❓1. How to check derailleur compatibility with my drivetrain?

  • Number of speeds: the derailleur must match exactly (10, 11, 12 speeds).
  • Shifter type :
    SRAM ↔ works with SRAM shifter.
    Shimano ↔ works with Shimano shifter.
    Both systems are generally not compatible (different pull ratio).

  • Derailleur capacity: must cover the size of the largest sprocket (e.g. 50/51/52 teeth in 12 speeds).
  • Cage :
    Short (SS) → cassette with narrow range (road, urban).
    Medium (GS) → MTB XC / Trail.
    Long (SGS) → large cassettes (e.g. 10–51).

  • Mounting: standard hanger vs cage type UDH (SRAM Transmission AXS).

❓2. How to choose based on my riding style (XC, trail, enduro, DH)?

  • XC / Marathon: Light weight, medium cage, precise and fast operation. Efficiency-oriented models (e.g. Shimano XT / SRAM GX).
  • Trail / All-Mountain: Robustness + wide gear range.
    Derailleurs with high-performance clutch (anti-shock/anti-chain slap).
  • Enduro: Reinforced derailleur, rigid cage, anti-breakage protection. Powerful clutch to prevent noise and chain drops.
  • DH: Derailleur short cage, ultra resistant, very specific cassette. Priority on chain retention rather than gear range.

❓3. Which technologies and options should you prioritise?

  • Clutch: essential for MTB → reduces chain drops and noise.
  • Mechanical vs electronic choice (AXS) :
    Mechanical → reliable, economical, easy to maintain.
    Electronic (SRAM AXS) → exceptional precision, self-adjustment, cable-free, but more expensive.
  • Profiled upper pulley: improves precision on larger sprockets.
  • Direct mount (UDH Transmission): Stiffer, more precise, designed for modern compatible frames.
    Highly resistant to impacts.

❓4. What materials and which range level to choose?

  • Aluminium: excellent weight-to-strength ratio.
  • Steel: very robust, ideal for tight budgets or intensive use.
  • Carbon / composite: lightweight, often high-end, good stiffness.
  • Bearings :
    Plain bushings → economical.
    Sealed bearings → better durability and smoothness.
  • Moving up the range = + precision, + stiffness, + silence, + durability.
