Shock Absorber Type 643 Competition QS Preload Adjuster:Hook Wrench Rebound damping can be fine-tuned

Rebound damping can be fine-tuned through an open-bleed system with 22 clicks

but omits the compression reservoir and the option for high- and low-speed compression adjustment

when braking — which makes the suspension feel unbalanced and reduces overall stability and riding safety

The factory setup can feel harsh over sharp bumps and vague over chatter

The reservoir is mounted at an angle and can swivel, offering numerous installation options on space constrained bikes. A solid milled upper mount integrates the high and low speed compression adjusters. Both compression and rebound provide 22 clicks of adjustment for uncompromised fine tuning. A pressure control valve prevents hydraulic blocking and tames sudden impacts. Spring preload is
