mecanum wheel choice

We highly recommend choosing either the goBILDA Mecanum Wheels v2 or the REV Robotics Mecanum Wheels, as they are the gold standard for quality, performance, and mounting options. According to Game Manual 0, both of these options feature ball bearing supported rollers, which minimize friction and allow for superior strafing compared to bushing-based wheels. The choice between these two depends on your space constraints and shaft system: the goBILDA wheels have a 96mm diameter and 38mm thickness with highly versatile mounting options, whereas the REV wheels offer a more compact 75mm diameter but are slightly thicker at 40.8mm and may require adapters for non-REV shafts 12.

While other wheels like the Nexus Ball Bearing or AndyMark Heavy Duty wheels are viable if you already own them, Game Manual 0 notes they are wider, more expensive, or use bushings that degrade strafing performance. The documentation explicitly advises against purchasing oversized 6-inch wheels or low-performing options like the TETRIX and AndyMark Standard Duty wheels, which suffer from fragile parts, hard plastic rollers, or poor set-screw hubs 234.
