Tamiya 22021 - GB-01S Off-Road Aluminium Pinion 16T  [22021]

Durable Pinion for TamTech-Gear GB-01S

The Tamiya 22021 - GB-01S Hard Coated Aluminium Pinion Gear (16T) is an upgrade aimed at improving longevity and drivetrain feel on GB-01S cars. It balances strength with low mass to support spirited driving on varied surfaces.

Advantages of Hard Coated Aluminium

Hard coating enhances surface hardness and resists scoring better than untreated parts, extending service intervals during regular club or recreational runs. The aluminium core helps keep rotational inertia down for snappier throttle response.

Direct Compatibility with GB-01S Chassis

Engineered to match GB-01S gear geometry, the Tamiya 22021 - GB-01S installs with minimal fuss. This means faster turnarounds at the track and fewer alignment tweaks after fitting.

Suitable for Both Racing and General Upkeep

As either a performance upgrade or a durable spare, this pinion delivers consistent meshing and helps maintain drivetrain efficiency. Its quality finish and fit make it a sensible upgrade for hobbyists who push their models regularly.
