yes ypou should look at tubus, im not sure about the suspension racks they make but the standard racks are with out a doubt the best period, i know they make a suspension rack for front suspension but im not of the details their website will show you all you need, also if yoiu are in Us and getting hold of a tubus is problematic then try old man mountain, ive heard good things about them but as i say the tibus are the best anyone who goes long long distance uses them .
In US a guy on ebay wayne.....of batsell sold me mine check him out..of you want any more info let me know, but a web search should pul up both
