Sure Grip Quad Roller Skate Plates Avenger Magnesium 3 Fits Boot Size 7

  

Plate is a 45 degree double action plate with adjustable pivots. Originally designed for short track speed skating but re-imagined for Roller Derby in the early 2000's.

Lightweight Magnesium plates, white powder coated, DA45 black aluminum trucks with steel hardened 8mm axles, hollowpoint kingpins, Sure Grip Purple 85a Super Cushions (4 barrel & 4 conical), and a rubber Carrera toe stop. Includes axles nuts and mounting hardware. The DA45 truck is very unique when compared to other trucks on the market. Due to its extreme angle it must use a special set of cushions, one "barrel" and one "conical" cushion. We developed a special urethane with 4 different hardness levels to fine tune the action of your skate.

Blue - 72A Yellow - 79A Purple - 85A Red - 93A. Pivot pins are not factory adjusted. Always adjust the pivot pins so that the ball just touches the bottom of the Delrin pivot cup. The pivot pin adjustment should be checked regularly once installed. Do not assume the pivot pin adjustment is correct if no movement is felt when checking the adjustment.

It could be adjusted longer than necessary. Pivot pins adjusted too long can cause the skate to have an unpleasant "darting" feel when skating. If the pivot pin ball does not touch the pivot cup you will be able to press down on the truck assembly and feel or see a slight movement of the pivot pin into and out of the cup.

Adjust the pivot pin until the pressure applied to the truck no longer results in this movement. When satisfied that the pivot pin is resting with slight pressure in the pivot cup, secure the pivot pin lock nut firmly against the truck housing.

NEVER skate your plates with the pivot pin lock nuts improperly tightened. Loose pivot pins will self-adjust and possibly damage the threads in the trucks.
