The GPM AW1906H is a purpose-built 1.9" aluminium wheel offering aimed at hobbyists focused on traction and control. Constructed from high-tensile aluminium, the wheel maintains a low unsprung mass while providing robust service life. The integrated brass pendulum weight shifts rotational inertia to enhance tyre contact on steep or irregular surfaces. Deep-groove tyre patterns complement the wheel design to deliver consistent bite when negotiating technical sections.
