Enve 14G Internal Brass Nipple – 3.2 mm Square-Drive

The Enve 14 Gauge Internal Nipple (also referred to as an ‘upside down’ nipple) are required by Enve on all of their rims.

These internal nipples are made from brass with a mechanical thread locking crimp to help reduce the chance of vibration loosening.

Notes on usage

Wheels built with internal nipples are more prone to spoke breakages at the spoke thread near the top of the nipple. This is caused by a bending action on the spoke as it exists the rim cavity to align with the hub flange. If the spoke threads are not fully submerged in the nipple, a stress riser on the root on the spoke thread may develop. To counteract this problem, we recommend using spoke lengths that are longer so that at least 1-2mm of spoke thread protrude through end of the nipple when the wheel is built. Effective Rim Diameter measurements for spoke length calculations need to be adjusted to account for the desired spoke length. The only exception for this approach would be in an extremely shallow rim when the spoke threads might protrude too close to the rim holes and rim tape. Such rim profiles are extremely rare.
