I just mounted my Planet Bike fenders on the Cannondale. I went to the hardware store to add a bracket to my OMM front rack to which I attached the fender bolts - works beautifully. I zip-tied the top to just below the Headshok.
The rear rack attached quite easily and sturdily with bolts on the eyelets and zip ties at the seatstays and at the BB. Sturdy as can be.
If anyone would like to see pics, PM me.
