Sapim Internal Alloy Nipple
| Article number: | Spokes |
| Availability: | Out of stock |
Sapim Internal Alloy Nipples are designed for wheel builds that use internal nipple interfaces, commonly found on aerodynamic road and gravel rims. Manufactured from 7075 aluminum, these nipples provide a lightweight solution while maintaining reliable thread engagement and consistent tensioning.
Unlike standard external nipples, internal nipples eliminate the rear slot, reducing the risk of rim bed damage during installation. The extended threading allows for faster spoke engagement, while the rounded shoulder improves load distribution at the rim interface—helping reduce stress concentrations in lightweight rim designs.
Features
- Lightweight 7075 aluminum construction
- Designed specifically for internal nipple rim systems
- No rear slot to reduce risk of rim bed damage
- Extended threading for faster spoke engagement
- Rounded shoulder for improved load distribution at the rim interface
- Standard 2.0mm / 14G compatibility
Best For
Best suited for aero road, gravel, and high-performance wheel builds that use internal nipple rims where a clean outer rim surface is preferred. Internal nipples are commonly chosen for aerodynamic wheelsets and minimalist rim designs, but they require more involved service compared to external nipples.
For easier maintenance and adjustment access, builders may prefer traditional external nipples. Internal nipples are typically selected when aero efficiency and clean rim profiles take priority over serviceability.
Wheelbuilding Notes
Internal nipples require specific tools for installation and adjustment. A dedicated internal nipple wrench such as the Park Tool SW-15 is recommended for proper engagement and control during tensioning.
Because adjustments require tire and rim access, internal nipple systems are typically best suited to precision-built wheels where long-term stability minimizes the need for frequent truing. For complete builds, consult our expert wheel builders for optimal spoke, rim, and nipple selection.

Cross-Linking Suggestions
For proper installation and adjustment, pair these nipples with the Park Tool SW-15 Internal Nipple Wrench. Builders comparing options may also consider external alloy or brass nipples depending on serviceability and long-term maintenance preferences.
