A park & street frame with geometry designed for 24” wheels only. Perfect for low travel suspension forks (60-100mm) or rigid forks. Medium front-end length perfect for 24” wheels and a short compact rear end with a high BB. The head angle is quite steep which makes for quick handling and easy front wheel tricks. The chain stays will let you adjust the rear wheel position within the 365-381mm range. The Spark head tube is designed to work with an integrated headset (the most popular BMX standard - Campy spec). It comes with a standard threaded BB shell so you can easily fit your favorite mountain bike cranks. Rear-end was redesigned for 2012. Long smooth tapers added on both chain stays and seat stays give perfect clean look and plenty of thickness to make a strong connection with new smaller and prettier dropouts (w/o a derailleur hanger). There are no cable guides attached permanently to the frame - we provide removable 3M cable guides if you need brakes. The Spark has a short seat tube extension over the top tube and integrated steel seat post collar for 25.4mm BMX size seat post. The frame comes with disk brake mounts, and fit rotors up to 185mm (no V-brakes mounts). Custom butted tubes beefed up in the stress areas keep weight low and strength high. An additionally reinforced top tube / seat tube junction is tough enough to survive abuse from tailwhips and 360’s. The Spark is an advanced frame made from high quality double butted 4130 cro-mo steel at a great price!
