Demolition Revolt CranksDemolitions Revolt cranks were proven and tested by there whole team for a whole year before they were released! If that doesn't give you confidence in how tough these cranks are we don't know what will. They've added a new heat treatment process with the addition of thicker tubing and made them with a stiffer shape, all for those that need the security of a stress free crank. The Demolition crew stands by them and swear they are the strongest cranks
