I live on a pretty bumpy road, so it will be interesting to see how they fare,I am anticipating a bit of noise from the panners banging back and forth on the springs ,so I hope I am wrong..Soon find out tomorrow.By the way, the helmet "locks"are as useless as tits on a bull.I easy removed my helmet off the locked bags.I reckon a mod using stainless cable would be in order.I might have been tempted to go the corbin beetle bags ,but I have heard of very slow service from them .Its a shame the Tsuzakumis or whatever theyre called dont go on Rockets yet!
