10 Teletype Shock Absorber Type 643 Competition QS. Swiveling, diagonally mounted compression reservoir. The reservoir is mounted at an angle and can swivel, offering numerous installation options on space constrained bikes. A solid milled upper mount integrates the high and low speed compression adjusters. Both compression and rebound provide 22 clicks of adjustment for uncompromised fine tuning. A pressure control valve prevents hydraulic blocking and tames sudden impacts. Spring preload is infinitely adjustable via the supplied hook spanner or optionally hydraulically. The reservoir angle can be re indexed later by any trained Wilbers partner. Product may vary from picture.
