The CA-520 is the newest model from Firmstrong, with a new frame design. The CA-520 is designed to give riders maximum comfort with a forward pedaling design and lower seat tube. The seat can sit lower to the ground while allowing full leg extension because of the pedals being shifted forward. It will be hard to find another cruiser or any bike for that matter as comfortable as this. In addition, the CA-520 comes equipped with a 7 speed Shimano derailleur. The gears allow for easy riding when doing long distance or up hills. The handbrakes provide maximum stopping power with little exertion. The handlebar position is set at almost should height which enables your back to be straight while riding and it puts less stress on your shoulders. The CA-520 is the equivalent of other high end, more expensive city cruiser bikes, for less money, while providing the same features.
