Wilbers shock absorbers type 640. The basic edition of the Wilbers Adjustline mono shock absorber comes along with the same technology as the more complex versions. The difference is that here we leave out the compression reservoir and thus the options for adjusting high- and low-speed compression. Nonetheless this shock absorber does not make any compromises concerning response behavior or durability. The radial piston, wet run, teflon guided self-aligning bearings and other features redefine the quality of a standard shock. Like usual the spring preload can be continuously tuned and the rebound can be set over an open-bleed system in 22 clicks. Please note that this is a fully customized shock so you need to fill further information regarding your ride. Product may vary from picture. WILBERS shocks are specially manufactured to your requirements and therefore CANNOT BE RETURNED.
