DT Swiss Pro Head Pro Lock Nipples

Brass is significantly more durable and corrosion-resistant than aluminum, making it the preferred choice for high-stress builds like e-bikes or wheels intended for year-round, all-weather riding. While they add a small amount of weight, the trade-off is superior longevity and a lower risk of spoke breakage.

The Pro Head design features a spherical contact surface that allows the nipple to pivot slightly within the rim. This automatic alignment prevents the nipple from tilting or binding against the rim hole, which makes tensioning spokes much smoother and helps ensure a more stable, long-lasting wheel build.

No, these nipples feature an integrated, patented locking system that prevents vibration-induced loosening. You do not need to add any external thread-locking compound, as the built-in mechanism is designed to keep your spoke tension consistent over time.

Yes, these nipples are designed for standard 2mm spoke thread diameters. They are a direct fit for most standard wheel-building projects using traditional spokes.

While they are excellent for any high-stress wheel build, they are specifically optimized for e-bikes. The design handles the higher torque and significant deflection angles often found in e-bike wheel builds better than standard nipples.
