I have a similar question to Non-quick release through axle - a few questions. My rear axle is similar to that one so I seem to be sorted from that question.
However, the front one is different. It does have a lever, but not a quick-release one I am used to or which I can find in all tutorials. It also has an allen key screw in the centre.
The manufacturer is Mr. Control (12x100mm) and from the Catalogue I ques it could be the QR-MF5-12X type. The description just says "Lever can be adjusted from rotational position. Max force to 150kg".
For regular opening like changing a tube or tyre do I open the little bolt or do I use the lever? What does the little screw with much smaller torque rating? Do I need to have a torque wrench in the field with me for that one?
