CHOKEPOINT LENS
DOSSIER
ROLE
The RV/cycloidal reducer incumbent — the high-stiffness, shock-tolerant gear family used in waists, shoulders, and the base joints of industrial arms. Owns Slovak cycloidal maker Spinea (2023).
CHOKE POSITION
Held the RV side of the reducer duopoly for decades. RV is less humanoid-levered than harmonic (humanoids lean harmonic at distal joints), which insulates it from the Chinese harmonic assault but also dilutes its humanoid upside.
Key readouts, what makes the choke pay, what breaks it, and the catalysts on the watch — for every instrument on the board.
INVESTABLE EXPRESSIONS
This instrument is no · listed but practically inaccessible. The nearest accessible exposure is below — adjacent exposure, not the same chokepoint position.
PERFORMANCE
No market data available for this instrument.
