Rok Straps
If you ride a bike, you will need straps. I have tried many different kinds but you can see the engineering that went into these straps. I cannot say enough how much I love these straps.
First, the end loops allow you to strap to virtually anything on the bike. They do come in different widths and lengths (just get the size you need). I have 4 pairs of the smaller version and one pair of the larger version. I use the smaller ones to attach items to the to of my side panniers while the larger set is used to strap the back of my seat.
These are not cheap but they are worth every penny. I got two different sizes (long and short) to accommodate my various mounting points. These are great straps. I will not go with any others as they fit the bill for everthing.
