+ Measure the diameter of your upper rack struts. If these are round and a maximum of 16 mm thick, you can easily buy new matching hooks.
+ Does your bag have QL1 system? This you can tell by the fact that the hooks are screwed on top with hexagon socket. --> . You need per bag 1 x E162 (replacement hooks above). For larger carrier diameters than 16 mm there is no solution for QL1.
+ Does your bag have QL2 or QL2.1 system? Then the hooks can be opened without tools and moved to the right and left for adjustment. --> The correct replacement hook is E212, for the office bag = E192 (with adjustable handle). If your rack strut is thicker than 16 mm, the replacement hook E211 fits for rack diameters of 18 mm and E193 for 20 mm.
+ The lower hook on the bag can be adjusted on current models so: Screw on the hook, turn the plastic washer 90 °, so you get a little more distance to the luggage carrier, if it is too narrow. Installed here is the universal hook E194, which fits on all lower rails. Alternatively, E239 can be used as an accessory, this is secured with a screw (not tool-free) and has a distance of 16 mm.
+ You can find the spare part by entering the part number in the magnifying glass at the top of www.ortlieb.com.
