Sirris F43 CMX Front Fork for E Ride Pro SS 2.0

Fits: E-Ride Pro SS 2.0

The Sirris F43 pairs an oversized 43 mm chassis with the CMX (Compact Motocross) tuned closed-cartridge damper. Tool-free compression adjusters give nearly 30 clicks of quick external adjustment, and the direct-mount crown bolts to a 4-bolt direct-mount stem.

Spring rate

Pick the range that matches your weight. Sirris tunes the E-Ride Pro SS 2.0 fork in two ranges (rider weight without gear; 15 lb of riding gear is already built in). Rates are left/right.

• Medium, 140–180 lb: 3.6/3.2 springs
• Heavy, 180–220 lb: 3.6/3.6 springs

Drop clamp option: raises the front 25 mm for a 21 in wheel while keeping 220 mm travel. Raising the front keeps the bike balanced when paired with a longer shock that raises the rear.
