Rebound needle fork SHOWA 49 (Pair)

Upgrade the rebound adjustment performance of your Showa 49 forks with precision-machined variable taper rebound needles from Lainer Suspension. This upgrade improves adjuster sensitivity while helping maintain consistent damping behavior across the adjustment range.

Although small, this component plays an important role in suspension tuning. As a result, riders and tuners gain improved control and more consistent performance.

Technology Overview

In the OEM Showa 49 rebound needle design, opening the rebound adjuster increases bleed flow through the rebound circuit. At low shaft speeds, this bleed path influences hydraulic pressure within the cartridge.

Because the rebound bleed circuit is not fully isolated, increasing rebound bleed can reduce pressure differential across the low-speed damping circuit. As a result, low-speed compression support may slightly decrease. Additionally, minor hydraulic cross-talk between rebound and compression circuits can occur.

The Lainer variable taper rebound needle improves this behavior. Instead of rapidly increasing bleed area, the variable taper provides a more controlled and progressive change across the adjustment range. Therefore, rebound control remains consistent while minimizing unwanted changes to low-speed compression.
