BKU / MECHANISMS / ENTITY
Chain drive
Input: pedal torque at chainring. Output: rear sprocket / rear wheel drive.
bku.mechanism.chain_drive
INPUT
pedal torque at chainring
TRANSFER PATH
- chainring teeth engage chain
- chain carries tension
- rear sprocket receives chain force
OUTPUT
rear sprocket / rear wheel drive
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.

Incoming and outgoing edges are different.
Direction and relation vocabulary remain explicit. Association is not compatibility, causality, ranking or a handling prediction.
