Derailleur shifting

Input: rider shift command. Output: selected transmission ratio.

bku.mechanism.derailleur_shifting
INPUT

rider shift command

TRANSFER PATH
  1. control moves derailleur position
  2. chain is guided laterally
  3. chain engages a different sprocket/chainring
OUTPUT

selected transmission ratio

Observation sequence

  • identify where motion/force enters
  • trace the transfer path
  • identify the interface where output appears
  • verify the system state after intervention

This mechanism page describes system logic. It is not a component-specific repair procedure.

BKU004 · WORKSHOP VERIFICATION

A mechanism map narrows questions. It does not diagnose.

A mechanism map narrows questions but does not identify a fault or authorize a generic repair procedure.

QUESTIONS BEFORE PROCEDURE
  • Which exact product architecture is present?
  • Which interfaces participate in the observed path?
  • Which manufacturer document controls the next procedural step?
AUTHORITY GATE

Use the current manufacturer documentation for the exact product system before adjustment, replacement, compatibility or return-to-use decisions.

GRAPH NEIGHBORHOOD

Incoming and outgoing edges are different.

Direction and relation vocabulary remain explicit. Association is not compatibility, causality, ranking or a handling prediction.
