The Flux SE30 binding is from a company that has a reputation for being, smooth, predictable, reliable and easy to use. Many also love the way they ride. This is a slight step down from the Flux TT30 but still a great all mountain to freestyle binding. This is one of the best budget minded bindings and they fit a wide variety of riding styles.
Flux has some tech that is worth mentioning. The rear and front of the base plate can slide out to give your boot a better fit. Because of this Flux is right up there with Burton bindings in terms of adjustability. Flux has the advantage on the base plate because Burton only has a front sliding base plate. However Burton has the advantage over Flux in terms of adjustability of the high back rotation angle. Flux bindings have 3 positions where the burton is infinite. So if you like to line up your high backs with your heel edge you are more limited with Flux (see how to set up your gear). Flux also has some of the best and most comfortable straps and ratchets. Almost every year they improve on them.
The 2013 Flux SE30 there is a slightly new design that makes for a little better ride than 2012. It’s lighter and just as responsive. There isn’t a forward lean adjuster any more in the high back so it takes a little work to make it lean forward. If that is important to you you might want to go with another binding but let’s face it most don’t ever use it anyway.
The 2012 Flux SE30 has a new high back ankle strap and toe strap. The ride is still very similar though.
The 2010 and 2011 are very similar.
All in all this is a great binding for the price and it’s hard to find something of better quality in it’s price range.
