Pro Lock® is a process where a patented, dual compound, adhesive liquid is injected into the nipple thread, allowing for extremely durable wheel builds. By threading the nipple onto the spoke the glue is activated and starts to harden. With Pro Lock® retruing of the wheel is always possible with only a minimal decrease of its threadlock function.


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

  • The pre-applied, automatically injected thread lock liquid speeds up wheelbuilding and guarantees high quality wheel builds wheel after wheel.

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

All DT Swiss wheels are built with Pro Lock® nipples. Over the many years we have been building high end wheels it has proven itself times and times again. On big scale production and bike shop level, one-off custom wheel building alike, it is the simplest way of obtaining extremely durable wheel building results. This is why our whole range of nipples is available with and without Pro Lock®, for those who are already adepts and for those who will be in the future.
