Hi,
I also have one on a bike I do not use as my main bike. I like the style but I am also a little sceptical about the design in combination with the weight. I would not expect it to be super strong. But so far I have had no problems (but I am not using it often...).
I assume a 2-piece street bar is stronger, but in terms of functionality this one is much better in my opinion.
I would rather put it on the wall than selling it
