The Powerslide Pitch Control AL is especially developed for our Accel Carbon Frames. It is a small little aluminum block that can be either placed under your heel or under your bale. The block has little pins which perfectly match with Powerslide Accel Carbon frames to stop the wedges from slipping. Raise up your boots over the frame to avoid wheels touching the boot bottom (the Accel frames and boots are all designed to be as low as possible), or place it only on front if you want to avoid shin problems. For more forward lean you place the Pitch Control under your heel only.
