When it comes to weight or rollerskis, don't overlook the weight of your bindings. While rollerskiing is for training purposes, rollerskis are noticeably heavier than top of the line winter nordic skis. Weight adds up especially on long outings of 3+ hrs. We put all the skate bindings on the scale and weighed each twice. We will soon have the Fischer Turnamic binding plates which will be interesting to find out their weight together. However, it looks like Salomon nailed it with their Prolink Carbon and Prolink Pro NNN bindings winning by a significant amount. We love the performance of the Prolinks also using them daily when rollerskiing.
