Just received the new Uswe top tube. Ag today. Quality is good. Was confused at first as it has a fleece liner which I found weird. But it’s easily removable and instructions say it’s to protect electronics. There’s a tiny mesh pocket inside. Maybe you’d put a credit card in there or money.
I was able to put 9 gels in there which include the larger e-gels without trouble. I’d probably take a couple out as with just 7 in there the magnetic enclosure flipped over more easily.
Will install and ride it this weekend. Bit good first impression
