The PK5900 is always ready to launch from 0 to 100 when you are. It is loaded nearly all features of the PK7900 reference model. For the Asymmetrical Upper Construction GRAF add additional material on the inside of the boot at the very point where a lot of the energy is transferred from your leg to the skate. Additionally, on the PK4900 and PK5900 GRAF introduce a newly developed PURE nine-layer Pro Composite Quarter Panel that fits extraordinarily well to the skaters foot and has the exact amount of stiffness to transfer your full potential to the ice. For the new PEAKSPEED Lightning line up GRAF focused even more on developing a skate that sticks more to the antomical contours of the human foot. To achieve this GRAF developed pressing moulds that form the PURE Composite Material in a Contour-3D shape even before the boot is manufactured. Our anatomically shaped PEAKSPEED Lightning footbed provides optimal energy transfer with every stride. As in two models of the first PEAKSPEED skate line up the PK5900 is equipped with a pioneering Two-Phase FlexFit Technology inner life. The upper part of the lining is made of Flex Grip Microfiber and in the lower part GRAF used soft and breathable Nylon-Velours. Our anatomically shaped PEAKSPEED Lightning footbed provides optimal energy transfer with every stride. The GRAF ULTRA 5000 blade is one of the stiffest and lightest blades that are available on the market and directs every little movement one-to-one the edges.
