The Tamiya 15120 Narrow One-Way Wheel is built for Mini 4WD pilots who prioritise nimble handling and consistent corner exits. Its slim profile lowers lateral resistance and supports smoother line-holding on technical circuits without heavy chassis modification.
These narrow one-way wheels are compatible with numerous Tamiya Mini 4WD chassis and wheel hubs. The one-way bearing lets the wheel free-roll in one direction while providing controlled resistance in the opposite direction to preserve speed during turn transitions.
Adding the Tamiya Narrow One-Way Wheel can yield better corner speed and repeatable handling, which is especially useful on tracks with frequent direction changes. Many racers use this part to fine tune balance between grip and momentum.
