The Flux GM is the evolution of the GM30 and it has a slightly different flex for different sizes but still has a very similar ride to it’s predecessor. The GM is a great supportive all mountain binding and this year it reduced the price by a lot making this a great entry level binding as well as a good binding for an accomplished rider on a budget.
Flex: This has a medium to medium stiff flex that can handle most boards in the women’s line.
Adjustability: Very easy to adjust all around. There is a toe as well as heel adjustability and all the binding except for the disc is tooless.
Comfort: Very comfortable binding. The ankle strap is very comfortable and has little to no pressure points.
Heel-Toe Response: This is pretty responsive and it can handle most boards out there getting from edge to edge.
Tip-Tail Response: Many bindings these days have a reduced dead spot but Flux doesn’t. All of the binding has contact with the board. They reduced as much of the sides as possible but they don’t really get much of any of the base plate. Still it’s not too bad when it comes to a butter or press.
Boot Support: The GM doesn’t have the bigger asymmetrical ankle straps that the higher end mens bindings do and that kind of sucks. Most would want to pay a little more for a more supportive ankle strap but still even Flux’s smaller ankle straps lock in the boot very well. Also the ankle strap is on the inside of the heel loop and that makes for a more conforming grip.
Ratchet System: The ratchet system is great and is pretty glitch free. It’s smooth and cranks down really well. It also releases well too.
Shock Absorption: The thin EVA foot bed isn’t very shock absorbent. Its damp at high speeds but it’s a little hard on a bad landing.
