I have used them for decades & 10s of thousands of km's, the bags are well made & fairly waterproof, but i have never been a fan of the look of any top box. They make me feel like they are something a Volvo driver would own, lol, but that is my hangup, not yours ! 😀 Most of the Ventura stuff is an easy fit and i am curious to see if anyone has fitted one to a GT yet ? You can also hang on to them & transfer between bikes because the rack itself has hinges which swing back & forth to fit any of the side rails...So you only have to buy new side rails when switching between bikes...I also use the grab handle when i am not using the bag...
