Attention, the dimensions in the pictures do not match. You need a seat tube at least 30 cm long. The bag is 27 cm high at the lowest point, not 21 cm. Otherwise, well made and looks like it would hold up even when submerged in water. I liked it a lot and I'm sorry that it won't fit in my frame.

The opening is extremely inconvenient, fortunately I can modify it for easier and faster access but it is still uncomfortable, I don't feel like recommending it... but also carefully evaluate other solutions

Waterproofing, resistance and excellent value for money, this bag would have it all, if it were possible to open it on the side with a secondary closure, waterproof of course! Too bad, it deserved 5 stars!

Very good capacity. Attaches easily and holds well during outings.

Excellent full frame bag, made with excellent materials, high quality finishes, easy to assemble, stable even off road! Recommended!

I'm excited.

Decathlon always on top!

As for waterproofing, nothing to say, you can store things there without fear of rain. The scratches are not very practical to install and wear out quickly but there is no real miracle solution. A little disappointed by the capacity, it is difficult to find the corners and it ends up filling up quite quickly and access to the bottom is not practical. The paint on my frame was scratched at the fixings but I left it permanently on my bike so I consider it normal. Good product though but don't expect to store much in it.

The bag is solid and well made, it can be assembled quickly, it is absolutely not annoying, in the sense that it does not bother pedaling, I have already done numerous outings with it, I find it awkward when inserting objects, the inlet is very stiff and you need to force yourself to pass the objects through, the watertightness has not yet been tested.

The bike grip tapes should be longer for electric bike frames as the bars are much wider

The bag seems very robust, once the scratches are well placed it holds well in place on the frame. It's a bit of a puzzle to fill in, but once it's done and done well, the objects stay in place and don't move all over the place. The opening is not very big, but that does not bother much. The walls do not deviate too much if it is well loaded and therefore it does not rub on the legs!

Bag of good quality, sturdy, not too wide so no discomfort to pedal. Two improvements: the first is the opening system, not very practical, you almost want to remove the bag from the frame to take out the things at the bottom. The second is the size, I thought the pannier would fill the whole frame but it didn't. Suddenly we lose a few precious liters and the possibility of putting other accessories on the frame (lock, bicycle pump). Several sizes would be appreciable depending on the bike in order to completely fill the frame and not waste space.
