Pololu Multi-Hub Wheel w/ Inserts for 3mm & 4mm Shafts — 80×10mm, Black (2-Pack)
One wheel set, four shaft fits. The Pololu Multi-Hub Wheel #3690 is a versatile pair of 80mm diameter wheels with grippy silicone tires, designed for fast robot builds and clean drivetrain upgrades. What makes it special is the included interchangeable collets—so you can mount to 3mm or 4mm shafts (round or D-shaft) without hunting for a different wheel model.
- Multi-hub mounting: includes collet inserts for 3mm round, 3mm D-shaft, 4mm round, and 4mm D-shaft.
- Secure grip: collet + metal plate clamp the wheel onto the shaft for less wobble and better torque transfer.
- Traction upgrade: silicone tires help your robot avoid slipping on smooth floors.
- 2-pack: includes everything needed for two wheels (left + right).
