PENNINGTON EXT. SPRINTER 1.25MM BLADES The Extreme 8000 series directs the power where you need it, not only is the blade to tube offset, but the tube to bracket offset as well. This aims the line of force from the boot directly to the centre line of the blade giving you more power and control where you need it, at the ice surface. On this model we have extended brackets specifically designed for the express purpose to distribute the power from the push more evenly along the blade eliminating small high stress areas on the tube. This blade was specially designed for performance and durability and can take a serious thrashing when maximum force is called for. Blades have fine tuned forward/backward bracket adjustment for personal positioning preferences. Size : 16 - 16.5 - 17 - 17.5 - 18
