PLEASE NOTE: Compatible with Evo, Supersix, SystemSix, CAAD10/12/13, and Synapse 2017 and prior frame models. This item is NOT compatible with 2018-2021 Synapse frames as the inner chainring bolt head can contact the chainstay causing damage. The shape of the drive-side chainstay on 2018-2021 Synapse does not provide enough clearance for the bolt heads.
