The Ride Optimo is the more sturdy high end version of the Ride Nitrate Contraband that has better shock absorption. The new ease of entry toe strap is rather weird and we aren’t sure how we feel about these bindings. The Nitrane line is love or hate. The one strap adjustment is what K2, Flow and Gnu are all doing with their bindings but none of us at the good ride feel it takes that much longer. Most of us actually think it takes away from making a binding perform better. Another problem is the how much effort it takes to get these bindings set up for your shoe size. Watch the set up video. It’s a joke compared to some bindings like Flux bindings that are almost toolles. Another problem is when your on the hill the toe strap can not be adjusted when the binding is on the board. So if you need to adjust it’s a major production with many tools to get everything set up. Another thing is the rubber on the toe strap seems like it wont’ last a long time but we aren’t sure of that since the Nitrane’s are only in their second year. The Optimo seems to have a more sturdy strap so that’s a good thing. The new high back is rather goofy looking but its performance is better than the 2010 model.
