Compression Adjusters
The HSC and LSC Adjusters are located at the top of the cartridge.
HSC: 6 Clicks (7 different Tunes)
LSC: 23 ± 2 Clicks
Setup Guide
ZETA Cartridge Setup
This guide explains the adjuster layout and the basic function of each damping setting.
Use the Tune Calculator below to find your recommended baseline setup.
High-Speed Rebound Adjuster
The HSR adjuster can be accessed by loosening the top cap assembly a detail description is given below.
HSR: 6 Clicks (7 different tunes)
Low-Speed Rebound Adjuster
The LSR adjuster is located at the bottom of the cartridge.
LSR: 20 ± 2 Clicks
Settings Reference
All settings are counted in clicks from closed.
Closed means turning the adjuster clockwise in the “+” direction this results in the highest damping forces. Open means turning the adjuster counter-clockwise in the “–” direction this results in the lowest damping forces.
Right Side Up Forks:
To access the HSR adjuster, remove the compression adjusters by first removing the M3 screw with a TX10 tool. Then use a HG cassette tool to loosen the top cap assembly from the fork.
By lightly lifting up the cartridge and wiggling left to right, the HSR adjuster can be engaged. From there rotate clockwise to fully close and then count the clicks in the anti-clockwise direction.
Reinstall the top cap assembly with a cassette tool and tighten to 28 Nm. Finally reinstall the Compression adjusters with the M3 Screw. Make sure to hold the LSC adjuster while tightening, otherwise internal components might be damaged.
Up Side Down Forks:
For USD Forks the HSR Adjuster can be accessed without loosening the top cap assembly.
First, uninstall the front wheel. Then lightly pull the right fork leg out until you feel resistance. By wiggling left to right the HSR Adjuster can be engaged. Viewed from the bottom, turn clockwise to fully close, then count the clicks in the anti clockwise direction.
By pushing in the fork leg again, the adjuster is disengaged. Reinstall the wheel and you are set.
Adjuster Details
HSC
High-Speed Compression
HSC Adjusters sets the overall compression support of the cartridge. Unlike a conventional high-speed adjuster there is no preload on the shims or an orifice restriction leading to a very progressive damping behaviour. This adjuster simply scales the damping forces up and down over the whole suspension speed range.
Typical situations
Support under hard compressions, bigger impacts, jump landings.
More HSC
more overall support, more feedback on sharp impacts, more bottom-out resistance.
Less HSC
Less overall support, better bump compliance, more travel usage on bigger hits.
LSC
Low-Speed Compression
LSC adjuster fine-tunes the low-speed compression behaviour around the selected overall tune. It mainly affects slower fork movements caused by rider input, chassis movement and small bumps.
Typical situations
Braking, pumping, weight shifts, berm support, and general ride-height control.
More LSC
More support under rider input, less brake dive, a firmer platform, more feedback on small bumps.
Less LSC
More sensitivity, easier fork movement, a softer feel under small inputs, less support under braking and for weight shifts.
HSR
High-Speed Rebound
HSR adjuster sets the overall rebound tune and is usually selected based on spring rate. It controls rebound speed especially at higher spring forces deeper in the travel, such as after larger impacts or landings.
Typical situations
Large obstacles, landings, deep travel events, steep terrain, and moments where the fork returns from high spring force.
More HSR
Calmer and more planted feel, very stable chassis movement, more controlled recovery after big hits. More effort may be needed to lift or bunny hop the front end.
Less HSR
More lively response, faster recovery, and good traction in high-speed chunky terrain. Less stable on big hits, landings, and steep terrain.
LSR
Low-Speed Rebound
LSR fine-tunes the low-speed rebound behaviour around the selected overall rebound tune. It mainly affects general fork return speed and travel recovery.
Typical situations
Corner exit, rolling terrain, traction, rider input, and repeated slower compressions.
More LSR
Slower return speed, calmer chassis movement, and more controlled recovery.
Less LSR
Faster return speed, more lively feel, and quicker recovery between inputs.
