The binding's durable aluminum toe piece and unique "turntable" heel design offer expert freeskiers a responsive connection between boot and ski for instant power transmission and precise ski control. It features powerful shock absorption and travel with confident retention and release for aggressive skiing.

Choosing your brake size is based on your ski width. The brake should be as close to the ski waist width as possible and no more than 10mm narrower or wider. For example a 100mm brake fits 90-110mm waist width skis.

Choosing the right binding model is dependent on your weight which determines which maximum DIN # you need. For example according to the chart below people weighing up to 100 - 200 lbs / 45 - 90 kg should get a binding that goes up to 12 DIN. It's also common for some experts and pro skiers to choose a higher DIN # even though it's not necessary.
