Description:

FingerTech Minisumo Wheels are top-quality competition wheels.

- The fiberglass-infused nylon hubs are designed with a ring of captive holes for locking the tire tread in place.

- Tire tread composed of Shore A20 polyurethane makes these the highest traction wheels you can buy.

- The wheel is designed to envelop a 16mm gearbox. Perfect where length is a concern. (Two Gold Spark motors with these wheels will fit into the 10cm width limit of minisumo events.)

- An extra-long setscrew allows you to easily tighten the wheels onto a 3mm motor shaft.

- Setscrew is accessed through tire. (Don't forget your 1/16" hex wrench)

Features:

Hub material: Fiberglass-reinforced nylon - "lock channels" ensure the tread can't peel off the hub

Tire material: Shore A20 polyurethane, professionally vacuum-degassed

Coefficient of Friction (against smooth unpainted MDF wood): μ=1.75 (Silicone μ=1.30, Rubber μ=1.05)

Diameter: 3.00cm (1.18")

Width: 2.16cm (0.85")

Inner diameter: 1.76cm (0.688")

Shaft bore: 3mm (0.118") - you can easily drill the bore for larger motor shafts

Weight: 12.6grams each (0.44oz) - light wheels mean you can add more weight to the bottom of your chassis; below the bot's center of gravity where it should be!

*It can take a day or two to mould your wheels - especially if the color is other than red.

Tip: Clean the tires with isopropyl alcohol wipes before each match for optimal traction.
