Rêve D have produced this new set of shock shafts in the popular SPM (Super Precision Machine Cut) titanium. Constructed from a lightweight high-rigidity titanium material with high-precision machining improves the dynamic performance of the damper and demonstrates smooth road surface tracking performance. The shaft surface has been micro polished using a special treatment that not only makes them ultra-smooth but also easier on O-rings and can help maintain the damper condition for longer periods of time. In addition to the E-ring for mounting the pistons, the set also comes with a gap adjustment shim that can be used when using thinner pistons. Additionally the M3 x 5mm FH screw joins their popular SPM titanium screw series. As with the conventional screw series, it offers weight reductions and more accurate machining.
