This wheel is designed to be driven by a 1/2 in. Hex shaft, but also allows for other motion hardware that utilizes a 1.875 in 6-hole bolt circle found in many AndyMark and competition robotics products. To mount one of these to the rear (flat) side, use a 250 Sprocket and Pulley Spacer. To mount one to the front, use a 550 Sprocket Spacer. This wheel does not include tread material, which is available separately to tailor this wheel's performance to your application.
Note: This wheel is designed to utilize rivets to attach the tread to the wheel. AndyMark recommends steel 1/8" diameter rivets with a 0.251" - 0.312" grip range. The wheel has been manufactured with no holes on the rim, as it is intended to be a blank canvas for teams to install rivets freely. An installation video is coming soon.
