The Galfer SB002 brake caliper adapter offers a +20 mm offset to increase the size of your brake discs. This allows you to upgrade from a 160 mm to a 180 mm disc, from 180 mm to 200 mm, and from 203 mm to 223 mm at both the front and rear. This adapter is compatible with Postmount standard brake calipers mounted on Postmount standard frames and forks. It requires 4 screws, 2 to attach it to the frame or fork (supplied with the adapter), and 2 more to attach the brake caliper to the adapter (screws not included, you can use the ones originally installed on your bicycle).lt;/div>
