One of the most important components on any BMX race bike is the crank set. The CLIQ Weaponz cranks are a 2 piece design comprised of 7000 series aluminum arms and a 24mm heat treated chromoly spindle which collectively provide an ultra stiff drive center. The arms also have chromoly pedal inserts for added durability. Also included is a 104 BCD CNC machined spider (Weaponz cranks are compatible with the CLIQ BB92 bottom bracket, however it's important to note that the BB is NOT included).
