Reserve rims offer the perfect balance of width and wheel size. The rim beads on the Reserve rims are thick, the material saved by optimizing the placement of the spoke hole reinforcements went directly into the bead, making it extremely strong without adding weight to the overall construction. The beads are hookless: this makes for a better fit with modern tires, but also simplifies manufacturing, which results in more consistent carbon compaction the technical way to say stronger rim.
