Description
If you’re running your bike hard and expecting consistent performance across varying terrain and riding conditions, stock shocks simply won’t cut it. The Progressive 444 Series delivers real-time damping adjustments through Frequency Sensing Technology—meaning your suspension responds intelligently to bumps instead of fighting them. For serious riders who demand precision handling and a compliant ride without compromise, this is the upgrade that pays dividends on every ride.
