2-5/8" Diameter Servo Wheel

Looking for a quick and easy way to attach a wheel to a servo for a wheeled robot? Here's the answer! This custom-molded wheel is designed to fit to most servo hubs (excluding Hitec), and give solid traction to your robot.

Solarbotics designed this injection-molded ABS wheel to fit most servo hubs (excluding Hitec), and give solid traction to your robot. Gone are the rubber bands, replaced by molded-on thermoplastic silicon tires with superior traction & wear characteristics!

Note: These best fit the old GMPW wheels, as the new GMPW wheels come with premolded rubber traction tires.

Tires sold individually

Gear Motor 2/3/8/9 Traction Tires

Although the rubber traction-bands on the OLD GMPW series wheels are good (and even better when double-layered), you need some "good grips" when you start playing mini-sumo in the advanced leagues.

Specifically molded to offer maximum traction, these 14 durometer Shore 'A' elastomer tires are the easiest way to upgrade your Sumovore to top-level competitiveness. As they are thicker than traction bands, they also increase the rolling diameter of the wheel from 67mm to 71mm.

Spare Traction Band for GMPW or SW Wheels

Black ain't good enough for you? Need more style, more 'tude for your robot? A new set of rubber on your 'bot is an inexpensive way to change the look of your robot!

These ain't your Mama's rubber bands either - they're a special soft-compound band for superior traction. Bands sold individually.

Solarbotics Large Rubber Wheels

Newly re-designed and manufactured, these beautifully machined aluminum hubs come with a generously thick rubber tire for maximum traction (ideal for minisumo, like our 1st place finishing Strong Bad!!).

The tire mounted on the hub measures in at 31.2mm (1.23in) diameter and overall width (including set-screw flange) of 11mm (0.67in) wide. The hub is drilled for a 3mm axle ideal for the GM12a-14a/18 series of gear motors! It's a nice, fat, beefy wheel ideal for small robots! Secure it to your motor shaft with the included 4-40 hex grub/setscrew (requires 0.050 hex wrench, like our HexW050).

Solarbotics 1-1/4" Rubber Wheels - Internal Set Screw

Redesigned at the same time as the RW2, we had these very similar hubs made to trim off a valuable 3.8mm (.15") by making the set-screw hole on the aluminum rim, underneath the tire. It means you have to remove the tire from the hub to tighten it, but well worth it for designs that need every millimeter of room! come with a generously thick rubber tire for maximum traction.

Don't forget to order PRet plastic retainers if you're planning on using these on standard 0.055" diameter music wire shafts!

Solarbotics Plastic Retainer

The PRet plastic retainer is a plastic nub designed to press-fit onto a 1.5mm shaft (like our RM1a). We use it as a hub for making micro wheels out of silicon tubing stretched over the PRet!
