If you thought the Dynafit Low Tech Race binding couldn't get any lighter, you thought wrong. Now checking in at a feathery 105g, the Low Tech Race Binding is lighter than before and maintains the same simple and streamlined design as previous iterations. The Low Tech Race gets its low weight and reliable strength through a thoughtful mix of forged 7075 aluminum, steel, and high tech syntetic. Dynafit has strengthened the heel unit with a stiff metal frame for more reliable performance, and uses separate pins for longer-lasting function over the traditional "U" spring.
