DT Swiss Pro Head Pro Lock Nipples

E-bikes exert significantly higher torque and stress on wheels compared to standard bicycles. These nipples are built from durable brass and feature the Pro Lock system, which resists the vibrations and high-load forces common in e-bike riding, ensuring your wheel stays true longer.

The spherical shape allows the nipple to pivot slightly within the rim hole. This automatic alignment ensures the spoke enters the nipple at the correct angle, which promotes even power transmission and reduces stress on the spoke threads.

These are standard 2.0mm nipples, which fit the vast majority of mountain and road bike rims. However, you should confirm your rim requires 12mm length nipples, as using the wrong length can prevent proper spoke engagement.

The Pro Lock system uses a patented adhesive injected into the nipple threads during manufacturing. Once the spoke is threaded in, the adhesive activates to lock the nipple in place, preventing it from loosening over time due to road vibration.

No, you can use a standard spoke wrench. Because the head shape is designed to prevent tilting in the rim base, you may actually find these easier to seat and tension than traditional nipples.
