Options For This Power Meter
BCD: BCD is bolt chain diameter. This is a measurement of the size of the crank spider. Most 50/34T and 52/36T rings use a 110 BCD, whereas 53/39T use a 130 BCD. If you are not sure what your BCD is, please contact us so we can help.

Crankset: The power meter is compatible with Specialized S-Works carbon cranks from 2013-current.
Chainrings: This power meter is compatible with 110 or 130 BCD 5-bolt chainrings based on the version ordered. In many cases, you can use your existing chainrings assuming they use the same configuration as the power meter you order.
What is BCD?: BCD (bolt circle diameter) is simply the diameter of a circle that passes through the centers of the bolt holes in your chainring. The BCD is usually stamped right on the chainring as either 110 or 130. It is important to know what BCD your crankset is because assuming you want to use your existing chainrings on your new power meter, you need to order the correct BCD.
