Banebots Wheels

[BobbyVanNess]

We used green 2 3/8" banebots wheels on our intake rollers this year. They worked incredibly well, but wore fairly quickly. We replaced them at the start of every competition, and they'd usually last until the end. On our practice bot, we had several of them actually wear down to the plastic. I cant say how the different hardnesses affect grip or wear though. We were thinking of replacing the green wheels with the harder blue ones, hoping they'll still grip, and last a lot longer (for demos/exhibits etc).

Anyone know how grip on discs differs across the grip colors?
