Roll-Line Pivot Lock Nut
*Only suitable for Roll-Line plates
Most modern roller skate plates and high-end vintage old-school plates come with adjustable pivot pins. But many skaters don’t know about the function and the relevance, and how the correct position can be adjusted. Mindless of the fact that the pivot is the central element of a roller skate truck and undamped forces hit the ball and socket connection permanently.
Correct adjustment prevents injuries
Properly adjusted pivot pins are important. The ball of the pivot pin should exactly touch the socket (bottom of the nylon or brass cup). An incorrectly adjusted pivot pin can
cause vibration when skating,
provoke the break of the king pin, or
destroy the nylon cups and ruin the plates.
All finally can lead to falls and injuries while skating.
Sold as single lock nut.
