These double black elastic bands are great for securing loose objects onto your bicycle rack, securing additional items onto a bag that is attached to your rack, and more!
If you have a carrier bag on your bicycle rack and need to attach a box too, the band will stretch around and keep them from falling off while you ride.
Elastic strap can stretch around most carrier bags for extra security while riding on rougher terrain.
Use the strap on the bicycle or detach it to take it with you!
Can be used for trekking bikes and city bikes.
