We have been working on these for the last 2 years and have
come up with some that weigh about 4 ounces and will fit in your
pocket(although we put them around the handlebar post because you can grab them with your gloves on). They can be used single, double or quad as shown in the pics. Quad is for pulling your ski around solo when not being driven. Double is for one guy pulling and one driving. Single is for 2 guys pulling and one driving when added length is needed. They are made out of a very high strength rubber that is very springy. Would like to get some more people trying them for feedback. We will be selling a few this year for about 1/2 price of what they will be at the shows next fall. The contact info is at this website.
