DT Swiss Pro Lock Nipples

Spoke failures are often due to material fatigue which is due to a low spoke tension combined with load changes of each single spoke.

Spoke tension decreases during operation (constant loading and unloading). Once a spoke-nipple bond has loosened, a spoke failure is inevitable! DT Swiss pro lock nipples prevent this loosening by maintaining a constant high spoke tension. The result is an increase in a wheels lifetime as well as a general higher loading capacity.

Countless internal tests show that the reliability and durability of a wheel built with DT Swiss pro lock nipples is increased up to­ ­twenty times compared with the use of standard nipples (see graphic). Our patented locking system is based on a special pre-applied dual ­compound adhesive, which coats the nipple threads. As soon as the nipples are twisted, the dual compound adhesive starts to react and is completely hardened after 6 - 7 hours. If necessary, the wheel can be used immediately after assembling. The wheel can be completely retrued several times but the adhesive effect decreases. An optimal adhesion happens only under pressure. It is very important, that the minimum spoke tension for a front wheel is approx. 900 N (90 kg) and for a rear wheel approx. 1100 N (110 kg). DT Swiss pro lock nipples are suitable for either machine-built or custom-built wheels. The use of oil or grease during assembling procedure is not recommended.

DT Swiss pro lock nipples are available with a standard or hexagonal nipple head. The hexagonal nipple is specially developed for aero spokes. It is turned in with a hexagon spanner, and the flat spoke can be held very close to the thread, ensuring that the spoke does not twist during the truing procedure.
