## Overall (mm)

| length | width | height |
|---|---|---|
| 27 | 27 | 134 |

**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- One page for the whole series: 3 sizes, one row and one file each. The size number is Fuji's nominal seat size, not the bore.
- Mud Hole lists two outside diameters without saying which part each refers to, so the model uses the larger as an envelope.
- Secondary source (Fuji US distributor).
- True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
- Secondary source: the numbers come from a retailer or magazine copy of the maker's specification.
