The construction is first rate, and the slender form factor means it doesn’t interfere with water bottles in my 51cm frame; the only half frame bag I’ve found that can do that. Yet I can still stuff a windbreaker in it, which is what I want it for. The only downside for me is the partition in the rear that sections off about 8cm of the bag. I know it’s for tools, but I’d prefer tonhave the whole volume be one larger, unpartitioned space.
I actually use this bag(XL) to carry an extra 48V 15ah battery for my Crew Method 750 E-BMX bike. With a slight modification to the zipper area, the battery fit like a glove! Clean, minimalistic esthetic, matches my black bike very well. I can even fit another small 10,000mAh fast charging brick in its side pouch lol. Love this bag, will be purchasing another fir another bike!
Finally a low profile frame bag that doesn't prevent or make h20 bottle grabs a nightmare. Doesn't hold as much as the big bags but that's obvious and there are other ways to store more stuff. This one is super light and tight in the negative space of the frame.
Love the color and style. Bag appears to be great quality, so I was both surprised and disappointed that one of the zippers is faulty.
I was a little worried but the S/M just fits inside the 51 cervelo aspero frame
