Cannondale One Chainrings

When using chainrings, make sure that they are flat at the point where they come into contact with the power2max powermeter, or that they do not have a shoulder/offset. Specifically, this applies to the original chainrings of the Cannondale One crank. We strongly advise against using these chainrings together with our powermeters.

We recommend using a new chainring set according to the selected bolt circle diameter (BCD). For the BCD 110 we recommend chainrings with 50/34t or 52/36t. For the BCD 130 we recommend 53/39t or larger chainrings.

Please also note that chainrings with less than 34t are not supported by the BCD 110.
