Used this for a 180mm rear rotor upgrade on my 2022 Bizango. Works great make sure you dont knock your brake lever whilst installing or you get rotor rub when fine tuning and tightening the bolts reset the pistons and start again if that happens it can be fiddly getting the allan key in for securing this is just the way the mounts on the bike are located and NOT a design fault with the product. Picture added to show finished installation.;

Su peso incluidos tornillos y el alambre por si quieres asegurar los tornillos y arandelas.31 g.
Lo he colocado en la pinza delantera de una suspensión lefty 8 . Lo recomiendo eso sí mejor apretar con dinamometrica.;

Facile da montare. Upgrade con disco da 180 e pinza Shimano XT;

Ludwig van Beethoven

Adattatore per allontanare la pinza dal disco di 20 mm e usare un disco piu grande. Usato per passare da 160 a 180 mm con disco Shimano Ice Tech e pinza a montaggio post mount. Infatti questo è l'adattatore per pinze post mount se qualcuno ha le pinze tipo IS serve altro adattatore. E' la versione più leggera ed infatti è più costoso. Se si vuole passare a disco 203 occorre adattatore + 40 mm. Controllare sempre quale sia il diametro massimo tollerabile dalla forcella andare oltre genererebbe una torsione agli steli molto pericolosa. Qualità Shimano sempre eccellente.;
