“The airlocks are a very solid, tidy and secure way of storing my bikes on the garage wall. Fixing was fairly easy, although requiring a 15 mm diameter drill bit was a bit awkward relative to a 14 or 16 mm. This 15 mm size is less common and the bit was not available in local DIY shops. Marking the holes and working out the final position of the bike needs care because of the weight of the lock. Once drilled the rest of the mounting was easy and the Allen key fitting was straightforward. Use is very easy and has really improved the security of the bikes in the garage. It's also handy doing minor jobs on the gearing with the bikes held off the ground.”
