# Traction

Recommended for use on drivetrains, ION Traction Wheels ([Product Family Page](https://www.revrobotics.com/ION-Traction-Wheels/)) come in a wide range of sizes, durometers, bores and material. Larger wheels contain the MAXSpline, but can be adapted to other bores with a separate [MAXHub](https://docs.revrobotics.com/ion-build/motion/maxhubs). Wheels with spokes have a bolt circle of #10 clearance holes patterned outward at 1/2in pitch and also have a 3/8in wide nut groove, which removes the need for a wrench when utilizing the holes on the spokes. Multiple wheels can be mounted flush next to each other when more surface area is needed.
