How do I anchor wall-mount hooks to studs if the mounting points need specific spacing?
The standard advice is to use the stud finder, mount the bike hooks on studs, and make do with a few lost inches. But if you must get those extra inches, you can mount a 2x4 on the wall horizontally, with at least each end anchored into a stud. And then you can install your bike hook on the 2x4.
