Heavy Duty Bike Wall Mount Hanger - Secure & Space-Saving Bicycle Storage Solution for Garage, Shed or Apartment - Perfect for Mountain Bikes, Road Bikes & Kids Bikes

After a long search this one with long shaft (13cm) is the only one suitable for my Hapro. I needed to place the horizontal flap on top for vertical wall hanging. The hook is very strong. The ball is not round, therefore there is no tight clamping in the beginning, but the enclosure is safe and theft resistant. The ball is 5cm max. Delivery at promessed date/time. 5 stars.
