Fork spring preload adjusters 19 mm by DUCABIKE for Ducati.
CNC machined of billet aluminum, anodized surface.
With the V2A attachment screw at the side, the adjuster can be mounted directly to the hexagon bolt at the top of the fork. This way pretensioning the spring for the current road conditions is a matter of only a few seconds. Essential for race tracks and also a useful gimmick for riding on normal roads.
