Show Description

Training with power is a great way to get stronger, faster. This crankset will help you do just that with its tried and true technology. By partnering with Power2Max, FSA made a reliable, precise power meter that won't break the bank. Carbon fiber crank arms bring the weight down and the spindle works with as many bikes as possible. Plus, ANT+ and Bluetooth Smart pair with pretty much every device around, so you can track your winter training on your phone and computer.
