I was looking at these racks only a few days ago as I really need to upgrade my Bagman "Sport" to an "Expedition" to accommodate my Super C.
The advantage of one of these for me would be that it doesn't clamp to the saddle rails, so I could set the saddle a bit further forward. Although that might leave me with the arse-bumping problem...
Anyway, does anyone know if one of these can take a Super C? I presume it does if it can take a Nelson, but would like to be sure. Also, I note the current design for the Bagman Expedition has extra support struts that attach to the seat stays. Does the Classic offer adequate support for a fully loaded larger saddlebag?
