Spank Spike and Oozy pedals have a pronounced bearing seat at the crank end of the pedal body, which sits almost flush with the crank arm. This may cause interference with some crank boots. If you wish to use protective crank boots with your Spike or Oozy pedals, it’s suggested to source boots with pedal holes no less than 27mm in diameter. If your crank boots have a hole that is less than 27mm in diameter, in most cases it’s acceptable to cut the hole to the appropriate size. You may want to check with the crank boot manufacturer first, as this may void your warranty. Spank Spoon pedals have axle flanges which are just under 20mm in diameter.
