Well...., quickfill received, looks very good and decent made. Also received the 32mm aluminium clamping system today, but that’s not gonna work. In rest I get 31.4mm diameter and opening it up carefully extends that to max 31.55mm. Needless to say a 32mm cilinder won’t pass that hole... I guess the error was in the conversion from imperial to metric Will email the supplier to see if this was a error in production.
