[QUOTE="Oldhaven, post: 78599, member: 2879"] [B]Alternate Fittings[/B] I am trying to fit an old set of Buco Twinmaster bags to my craven V rack, and in the course of thinking up ways to do it I came across these clamps that could be substituted for the original Craven clamps that fit on the 1/2" tube lifting handle and the 5/8" tube on the rack. The 1/4" Craven spool fittings on the panniers that the L shaped upper holders slide into could also be replaced with them, but their rubber bushings are tight when installed and tightened down. That is good on the rack tubes. since they will not move, but would make the panniers difficult to slide off the L holders unless a quick rease was used on one side the clamp . I got them from McMaster Carr and they are stainless with TPR vibration damping and not expensive. The flat SS bar across the back of the clamp has to be fabricated unless the clamp is mounted to a flat surface. They also move the 1/4" bolt point for rack attachments away from tube center, but I do not see that as a problem for my purposes. I can see from the variety of sizes that they might have other uses for mounting equipment requiring vibration damping to round tubes.
