 is the LARGER tube shaped Cushion. The LOWER Cushion is the one nearest to the Skating Surface and
 is the SMALLER Cushion.

Green = Flexible
Natural(Brown) = Medium
Yellow = Hard

The Roll-Line Cushions provides athletes the proper support of the skating shoe and give the most sensitive control, the greatest and absolute fastest response available from any skate, providing a sense of great stability and action.
Roll-Line Natural Rubber and Urethane Cushions both provide incredibly quick and fluid energy transmission from the foot through the skate to the skating surface.
The Roll-Line Natural Rubber Cushions are available in three (3) hardnesses and Urethane Cushions are available in five (5) hardnesses to provide 64 choices for the perfect skate alignment and control.
The Upper (Large) Suspension provides the Stability of the Edge, while the Lower (Small) Suspension creates the Deep Edges, Great Turns, Spins, and Loops. The Suspensions can be mixed and matched in both Rubber and Urethane and in Hardnesses to provide a VERY Custom skate Action, based on your weight, height, and type of Skating that you are doing. 
Usually the Upper (Large) Suspension is harder, because it is carrying the weight of the Skater, and provides the edge stability, while the Lower (Small) Suspension is often one (1) or (more infrequently) two (2) levels more flexible, providing great edges and changes.
 For LOOPS it is sometimes suggested to use an appropriate Flexible Upper (Large) Suspension, considering the Skaters height and weight and the small diameter Loops being Skated, with the Lower (Small) Suspension configured two (2) levels Harder. This configuration provides a skate that reacts and feels like the old and no longer available Hodura skate.

The list below is an integrated List from the Most Flexible to Hardest and combines both Rubber and Urethane Suspensions:
Green = Rubber = Flexible

Natural (Brown) = Rubber = Medium

Clear Green = Urethane = Extra Flexible

Grey = Urethane = Flexible
Clear Blue = Urethane = Medium

Yellow = Rubber= Hard
Clear = Urethane = Hard

Clear Yellow = Urethane = Extra Hard

Comparisons of Rubber to Urethane Elastomer Suspensions:

Rubber – Shorter Life, Temperatures do effect the response of Rubber, Less Expensive

Urethane – Longer Life, Temperatures have much less effect on Urethane, More Expensive.

If a Complete Set of one Colour and Hardness are desired, please choose that Item.

• • NOTE: The Hardness of Suspensions that are shipped on the Skate plates are determined by Roll-Line at the factory in Italy. They are based on the size of the Frame, and the expected height and weight of the Skater. Select other hardnesses and/or combinations of cushions if you want a very specific setup when ordering your Roll-Line plates.
