Why the SC4 cartridge is your best ally?

Simply put, it’s down to its specific conception with 3 independent compression ways, inspired from our up kit.
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.

The rebound is externally adjustable for the low speed. The high speed rebound shims stack will be set according to your expectations.
