## Notes

- A saddle's top is a compound curve with a cut-out: saddle-bag mounts, rail-mounted light and bottle holders and covers need the shape from a scan.
- Published: three widths, 143, 155 and 168 mm; 240 mm long; 7 × 7 mm rails (the standard round-rail size that saddle clamps take).
- A measured Xem scan is planned; until then this page carries only the published numbers and no geometry.
