Pro Lock is a process where a dual compound, adhesive liquid is injected into the nipple thread, allowing for extremely durable wheel builds. By threading the nipple onto the spoke the adhesive is activated and starts to harden. Re-truing the wheel is still possible after the adhesive has hardened completely, with only a minimal decrease of its thread-lock function.


  • DT Pro Lock nipples prevent the spoke-nipple connection from loosening

  • Wheel durability improves up to 20 times compared to non Pro Lock builds

  • Suitable for either hand or machine built wheels. Use of grease or oil not recommended

  • All DT Swiss nipples are available with and without DT Pro Lock
