Wilbers Zero Friction Progressive Fork Springs have several advantages over linear springs. A Progressive Rate Spring has the advantage of a rising rate resistance to compression. The benefit of this is that the spring can be soft enough at the start of the travel to offer a "plush" ride, yet be firm enough at the end of the travel to soak up the big bumps and dramatically reduce nose-dive under deceleration and braking.

Don't forget the Fork Oil!  You will need 1 Liter of 7wt or 10wt for these springs.

Please note:

7wt oil is recommended for general purpose and for more dirt road riding.

10wt oil is recommended for sport-oriented street riding.

Air chamber is 130mm with springs removed and forks completely compressed.

Instructions for setting air chamber: 


1) Remove fork spring and drain old oil. 

2) Compress fork fully with spring removed.
3)  Add oil until oil level is the prescribed distance from the top of the tube - this is your air chamber.
Piston rods should be pumped several times to dispel any remaining air before final measurement is made.
