2. TECHNICAL INFORMATION

The range of ROCO rear shocks consists of various versions for different
lengths of travel and/or wheelbases.
2.1 Spring system
Rear shocks Marzocchi you will fi nd coil springs, or air, used as
suspension mechanism.
2.2 Damping system
The damping load generated during compression and rebound of the rear
shock is controlled by the use of special hydraulic damping systems.
TST
The TST system allows the adjustment of hydraulic damping of the
compression thanks to a 5-position adjuster.
HSCV
The HSCV System, is based on a speed sensitive type valve, and it
provides a compression damping control increasing with the rear shock
damping speed.

R
Thanks to the speed sensitive type valves, the R (Rebound) system
allows control of and rebound on the basis of the travel carried out by the
suspension. The R system allows adjustment of the rebound.
LO (Lock-Out)
The LO system operates on the hydraulic circuit, which adjusts the
compression and allows for the blocking of the shock absorber. The red
lever can be moved in two positions through a 90° rotation. If turned
clockwise, the lever opens the hydraulic circuit; if turned counter-clockwise,
the lever closes the hydraulic circuit and blocks the shock absorber. The two
positions are indexed with a "click", which prevents intermediate working
positions and ensures very fast adjustments.
