Frequently Asked Questions
Can I adjust these shocks without removing the wheels?
Yes — compression, rebound, and preload all adjust via hand-accessible knobs and the spring preload adjuster. Height adjustment requires minor removal.
What makes the 990 different from other adjustable shocks?
The dual-circuit deflective disc damping and high-pressure monotube deliver consistent feel throughout the full stroke. Most shocks have dead zones or unpredictable transitions.
Can I change ride height on the fly?
Yes — the 0.4 inch adjustable height eyelet lets you dial in ride height without special tools, though you may need to roll the bike to reset weight.
Do I need a tuner with these shocks?
No tuner required. Suspension adjustment is purely mechanical via the external knobs and preload adjuster.
