A double-ended tool for selected Mavic systems; the outside spline diameters and thread designation are distinct.
Six splines;5.5 mm outside spline diameter
Match the wheel/component and spline geometry rather than choosing from Mavic branding alone.
What this choice changes
The SW-13 serves the selected Mavic six-spline fittings described by Park Tool. Its smaller end has six splines with a 5.5 mm outside spline diameter. The larger rim-fitting end also has six splines, with a 9.6 mm outside spline diameter and an associated M7 thread designation. M7 is not a 7 mm wrench opening.
These contacts are different from an ordinary external-square nipple wrench and from the proprietary DT Tricon pattern. Even a shared count of six splines does not establish that those receiving shapes interchange. Choose by the exact Mavic wheel/component and identified fitting rather than the wheel brand alone.
The selected seller wording refers to 5.65 mm eyelets and 7 mm integrated nipples, which is not a clear mapping to the current maker’s contact dimensions. Those figures are not used here as exact-fit filters. Confirm the actual wheel fitting before ordering; the tool remains one double-ended wrench, with any spoke holder separate.
| Detail | Specification |

| Smaller maker contact | Six splines;5.5 mm outside spline diameter |
| Larger maker contact | Six splines;9.6 mm outside spline diameter |
| Associated thread label | M7, not a wrench opening |
| Scope | Selected Mavic systems; exact fitting required |
| Supplied | One double-ended SW-13 |
Match the wheel/component and spline geometry rather than choosing from Mavic branding alone.
M7 is an associated thread designation; it must not become a 7 mm wrench-size claim.
No. The maker identifies it as a thread designation associated with the larger fitting.
No interchangeability is established. Proprietary pattern geometry matters as well as spline count.
No. Identify the exact wheel fitting and confirmed contact, particularly because the selected seller’s dimensional wording does not map clearly to the current maker specification.
Selected listing details, manufacturer information and source images were compared. No hands-on trial or universal fit is claimed. Product identifier: B000YBHOOA.
