Just purchased my first bike haibike xduro cross 4.0. My only gripe is that there are not bosses on frame for water bottle and pump. I have scoured amazon and web and not seeing anything that’s aftermarket that I want to try. Most of the one I did find are basically zip ties and some sort of plastic nut/ boss that straps to frame. Since my frame has rectangular tubes these do not look very sturdy or fit at all. If you have a good solution please share link. I am about to the point that I will just use a seat back mount for water bottle and use frame bag for pump and needful things.
