@REI-JohnJ @JimB I want on this wagon.... We just purchased two Cannondale Topstone bikes. I ordered the Topeak disc mount rack. There is no way to get the front support down to seat stay. I could attempt to create a clamp for the seat post, and wonder if that is the only real option. It isn't obvious how the Axiom rack previously suggested would mount - again, no place to attach the front support.
Any suggestions other than build a clamp for the seat post?
