The new Rotation 10 binding marks the next step in the evolution of the Radical 2.0. The new Rotation 10 version maintains the advances of the Radical 2 10mm of forward pressure and the rotating toe piece and adds a few refinements. The toe piece is now spring-tensioned, so it auto-realigns to center making for a smoother entry experience. And the binding now integrates the heel unit into the baseplate, helping to strengthen and laterally stiffen the heel unit think reduced heel play that has been present in Dynafit binding over the years. Finally, Dynafit updated a bunch of internal heel unit parts to aluminum, saving 50 grams in weight over the Radical 2.0.
