I got a nice Basil.nl briefcase/pannier bag as a gift -- I put it onto the (purchased from) BF rear rack on my Pocket Rocket.

Found I have to slide it to the back part of the rack to avoid heel strike:



Which works fine, except that now it wobbles and occasionally touches the tire.

Any suggestions? If I swap-out the rack, my BF underbag won't fit any more. Is there such a thing as a "rack extender"? Or...?



Thanks
