In a normal spring, the coils are evenly spaced and compress at the same rate. For example, if you have a spring that has ten coils spaced a centimeter apart, and you push down one centimeter on the spring, the entire spring compresses one centimeter and each coil will then be 0.9 centimeter apart.
In a two-step linear spring (or one-step progressive), about half the coils have shorter spacing. As the spring compresses, the coils move closer.
At a certain point, the shorter spaced coils touch, effectively eliminating them from the spring. You then have a spring comprised of only the longer coils.
Hyperpro springs are an engineering work of art. Backing up this claim is a lifetime warranty against breakage.
Each spring is constructed of the finest grade of chrome-silicon wire and is guaranteed not to sag even after 1.000.000 miles of use.
Each spring is shot-peened for strength and durability and then polished to reduce friction and eliminate fork oil contamination.

Each kit comes complete with fork oil and full instructions on fitting and set up.
