Our SpinTake has three bore options, making it a viable part for both FRC and FTC! This product is ideal as an intake "wheel" for picking up game pieces of varying shapes. Made from natural rubber, the SpinTake is flexible, yet firm. Its unique shape also allows it to be oriented to stay within the robot frame perimeter initially but can reach outside just by spinning. These work in a similar fashion to surgical tubing fingers on an axle, but are easier to implement and provide a cleaner look with more consistent results. 
The Hex Bore options are designed to be an interference fit on their associated Hex Shafts. This means it will be a tight press to install but will resist slipping under load.
