The SON 28 is lighter than the previous (SON 28 Classic) version, has a bit less drag and is styled much like the SONdelux. They are available in Polished Silver (as shown) Silver Anodized, Black Anodized, Red Anodized and Blue Anodized; 32 and 36 hole drillings (blue, 36 hole only); standard connector for normal forks or SL and three basic types: non-disc as shown above, a Centerlock disc version and a version for ISO disc. Since the flange diameter is smaller than the current hub 40 and 48 hole drilling isn't possible, so a special version with larger flanges is made for 40 spoke and 48 spoke wheels.
