With its optimized, minimalist design and a broad drill hole pattern, the ultralight Low Tech Race 105 is the lighter (105 grams) and more responsive version in the Low Tech Race family. The binding is available in two versions: - Low Tech Race 105 Auto: an ascent-oriented version with a simplified locking system. - Low Tech Race 105 Manu: with manual locking system and thus conforming to ISMF standards. Optionally, the Low Tech Race 105 can have a adjustment plate mounted to it that allows a heel adjustment of 20 mm to enable great adaptation to various sole lengths. The lateral and vertical releases are both set to fixed values that were determined by our athletes over the course of several years as the best balance between safety and stability. Ski crampons can be worn if needed with the Low Tech Race 105 bindings. Just like all DYNAFIT bindings, the Low Tech Race is developed and manufactured in Germany.
