Miles Q. ★★★★★ Oct 22, 2026

I was pleasantly surprised by how solid this flywheel feels right out of the box—the oversize casting left plenty of meat for me to true it to exactly 3 inches. The straight spokes and heavy rim weight give it a nice, steady momentum even at lower RPMs.

David ★★★★★ Oct 20, 2026

The casting is hefty and true, and the oversize diameter gave me just enough meat to dial it in perfectly on the lathe. The 0.755" rim width holds up well under load, no wobble once finished.

George I. ★★★★★ Oct 18, 2026

The hub diameter of 0.728" fit perfectly on my shaft without any slop, and the oversize casting let me true it up exactly to 3 inches on the lathe. I'm impressed with the solid feel from the six heavyweight spokes.
