Originally designed as capstan roller for cassette tapes (remember those?), they’ve found a second life as high-performance wheels for tiny robots and in our own SolarSpeeder kit. This version of the wheel is 9mm instead of our standard 10mm wheels.


  • 9mm OD
  • 1.5mm ID
  • 7mm wide
  • Nylon hub

If you’re planning to use these as coasting wheels, they roll quite nicely on standard 0.055″ music wire. And our PRet plastic retainers do a good job of holding them in place.
