The wheel/axle assembly from a Vernier dynamics cart will fit on a pasco cart. Pasco wheels use unsealed bearings which age and gather dirt. Replacing the assembly with the Vernier equivalent will improve cart performance.
Vernier Dynamics System Axles and Wheels for Cart (WHEELS-VDS) refers to a pair of axles with four wheels, enough to retrofit one cart.
