Good product to leave a bike unattended few moments near the entrance of the supermarket. The security cable is easily clipped on its support ... The holder is easily attached to the frame if it consists of cylindrical tubes. If profile tubes, try to attach, + or - well, the support in the saddle ... Shape memory cable: very easy to carry as twisted (and relatively short); a little inconvenient to put in place because ... twisted! The cable is just long enough to fix the bike by the two wheels to the inverted U-tube fixed in the ground by municipalities. No chance against by attaching the bike with two wheels at a respectable plane. This product deserves 5 stars for its barrel price.
