Velcro strap for attaching Zipper series bags to the bike frame.
The straps are lined with a coated non-slip fabric, which gives the bag stability and also helps protect the paint.
In order to protect the paintwork effectively, the contact area between the strap of the bag and the frame should be secured with a protective self-adhesive film.
The straps come in two sizes: 23 and 32 cm.
23 cm version
The shorter one, with an overall length of 23 cm, is designed to be fixed on the top tube. It fits tubes with a diameter of 28-60 mm (or a circumference of 88-190 mm), so it will work well with both aluminum and steel frames.
32 cm version
The longer one, with a total length of 32 cm, is designed to be fixed on the main (oblique) tube of the aluminum frame, which in modern bicycles often has a very large gage. The 32 cm strap fits tubes with a diameter of 45-80 mm (and a circumference of 140-250 mm).
We use Velcro from the Spanish brand Tapcro, with high adhesion properties and long life.
Once the strap is fastened to the frame, the loose end should be cut off.
