I have been trying to find a bike storage solution for a very cramped blockwork shed. After endless internet researching I found Gear Hooks and ordered the double rail six bike rack. The instructions that come with the kit are excellent and it was a fairly straightforward job to fit. The hooks are fantastic and for me the best thing about them (and the reason i bought them) is the adjustability of the system. We have a mix of road bikes, mountain bikes and kids bikes - all different shapes and sizes. The rail system allowed me to get the hooks on the wall, then adjust their height and position to suit each bike. With any other hooks it would have meant re-drilling fixings to make any changes. It is a well designed system that has been built to a high standard. It seems very robust and should last pretty much forever as far as i can tell. I wouldn't mind a slightly wider hook for mountain bike tyres, but it holds a 3 inch tyre on a 50mm rim securely enough, with plenty of clearance for hooking and unhooking. I may buy more for getting the garden tools out of the way next. Highly recommended.
