CRITICAL DIMENSIONS
Cross-section drawing of the K-BSB-57 rim assembly. Five reference dimensions (A–E) are CNC-machined to the tolerances called out in the table and verified on a 5-axis CMM before every unit ships.
| REF | DIMENSION | VALUE | TOLERANCE |
|---|---|---|---|
| A | Band overall length | 229 mm | ±0.30 mm |
| B | Bead seat heel width | 32 mm | ±0.10 mm |
| C | Bead seat ⌀ | 1 447.8 mm | ±0.20 mm |
WHEEL-END ANATOMY
The complete 57" BEAD SEAT BAND wheel-end is a five-piece assembly. Every Kelios rim ships as a matched set — rim base, lock ring, side rings, and bead seat band — with the OEM-supplied hub remaining factory original.
FINITE ELEMENT ANALYSIS
Every Kelios rim design is validated under 1.4× rated load in a Von Mises FEA solver before tooling is cut. The K-BSB-57 was meshed at refined element size with concentration at the lock-ring seat and bead radii — the two locations where field failures historically initiate.
