# Compliant

[ION Compliant Wheels](https://www.revrobotics.com/ION-Compliant-Wheels/) are recommended for use with intakes and shooters, but not for drivetrains because of their "softer" material and deformation under a typical robot's weight. Compatible with the REV ION System and come in a wide range of sizes, durometers, and bores. The radial spoke profile allows for more consistent compliance and more compression than other compliant wheels. Larger wheels contain the MAXSpline, but can be adapted to other bores with a separate [MAXHub](/ion-build/motion/maxhubs.md).
