I have just erected my last gear hook rack having bought 3 bike hooks for it. My major decisions were where in the garage and how high on the wall. Finally decided to put close to a corner allowing for the handlebars of the mountain bike. The height was slightly more difficult to decide allowing enough space for the tyre to hook below the ceiling but wanting height off the ground for space. I did think some guidance might be helpful but all spaces will be different. As ever though once up a fantastic bit of kit. Luis was very helpful and quick to respond when I noticed a couple of fixings were missing. Definitely recommend gearhooks.
