Wilbers Powered by ZF Fork Type 46RR with Closed Cartridge

ACA — Air Chamber Adjuster (46RR ACA fork)
A standout innovation in the Wilbers lineup: a closed-cartridge system with external oil-level adjustment. Rebound (left leg) and compression (right leg) are each adjustable in 10 clicks, with spring-preload adjusters on both sides. Tuned wall thicknesses deliver optimal flex for exceptional grip and feel at lean.

The signature cylinders at the axle clamps house our patented Air Chamber Adjuster, allowing you to change the oil level externally by up to 10 mm in 0.5 mm steps — no fork disassembly required.
