Weighing nearly one pound per pair less than the classic TLT Radical, Dynafit's Speed Turn 2. 0 Binding is the successor of Dynafit's classic Speed Radical. It follows in the same light, fast, and simple footsteps, with rugged CrMo steel, stainless steel, and forged aluminum construction, 4 10 release values for bomber hold and consistent release, and 12. 5mm of adjustable length for use with different boots. The dual heel risers and rotating heel piece are easy to manipulate with poles and the toe pins provide all the reliability you'll need to conquer distant peaks or dip a toe into the rando racing pool. The Speed Turn toe has also been updated with a four hole mounting pattern, like the Radical, and features the locking climb mode and crampon slot that you'd expect from any Dynafit.
