Q: What does the I-beam spoke design actually do?

An I-beam cross-section puts material where bending loads are highest and removes it where it isn’t needed, the same principle used in structural steel beams. On the UP-03 that shape resists wheel flexion under cornering and launch loads while keeping weight down. Combined with the knurled barrel that stops tire slip, it’s a wheel engineered to stay rigid when a Plaid is working hardest.
