nitron track shock

[PieEater]

the Nitron "street" shock, is 2 way adjustable through 1 adjuster (compression/rebound) and also preload (and ride height?).
the "Sport" is also 2 way adjustable through 1 adjuster for compression and rebound, and also preload (and ride height?).
the "track" is 2 way adjustable, but has independant adjusters for compression and rebound, and also preload (and ride height?). It also has an external reservoir for the gas, which reduces fade on track.
the "race" is 3 way adjustable (independantly) and also has an independant reservoir.
and the "race pro" is basically a "race" with the hydraulic preload added on, and a bigger piston to reduce fade more.
Thats what I make of it from reading the Nitron site anyway

All these shocks have preload adjustment
The Street is the only one in the range that does not appear to have ride height (shock length) adjustment.
Neither the Street or Sport have independently adjustable damping (2-way), they have a single adjuster that affects both compression and rebound damping simultaneously.
From the Track upwards all shocks feature a remote reservoir and independently adjustable damping.
