This simple & lightweight tow strap works great stand alone with no accessories. It contains a high stretch bungee cord inside an ultra strong hollow webbing. It only weighs 140g. & has been designed to keep the strap from dangling to the ground/wheels while adding a very soft feel to the second rider so there is never a harsh jerk at the end. At max length it is 4,31 meter and only 1,4 meter relaxed. This will help you tackle larger rides together with younger or weaker riders. Rated One Size Fits All for all riders of any age, size or weight up to 227 kg. HIGHLY recommended is the Quick Loop add on Accessory for built in storage & fast easy connections to the trailing bike.
