“Seems like a great bag, but I haven't actually ridden with it.
The recommended fit was a bit off for my Large MCR. After bolting to the top tube, there was a centimeter gap to the down tube - a big gap for the provided bolts. I did mount it, but it caused the bag to stretch and deform, making the zipper want to bind. I got a longer bolt (M5x35, I think) and nylon spacer from the local hardware store that allowed for non-stretching installation, so I'm looking forward to the additional bike storage.”
