Why is the Up kit your best ally?

Simply put, it’s down to its specific conception with 3 independent compression ways.
Low speed for comfort on small hits, medium speed to manage diving and balance of the bike and finally a circuit dedicated to high speed/impacts to flatten the ground.

To go even to flatten the ground. To go even further the Up kit is sold with Fast’s CELL FOAM kit to make a 100% sealed cartridge.
Get a constant dampening, emulsion free thanks to the CELL FOAM.
