Very sturdy, very good finish, relatively tricky installation. Many Allen screws that will definitely need tightening from time to time, but they are easily accessible and are necessary for proper fastening. I keep the tool permanently in the triangular case under the saddle and there is no problem. You just need to pay a little attention to make sure it fits your bike; you have to ensure there is enough space on the seatpost or the frame to secure it.

Very good quality, sturdy construction... perfect fit.. it would only help if it had installation instructions

Very good construction, super lightweight, I don't know yet about its durability, it is easy to install! The package contains everything necessary for its installation, such as screws, rubber pieces that go between the clamps so that the bike frame is not damaged during tightening, and it also includes the necessary Allen key for tightening the screws.
- And as I saw, it can be adapted to any bicycle.
- I installed it on the bike and attached two bike bags on it, so it is convenient even for this case!
Visually and in terms of construction, it seems very well made. As for its durability, I will use it for a while and come back later. As for the 50 kg it says it can withstand, I don't think so, because it is made of very light materials.

Very easy to install, lightweight, and very good fit on the bike for the money, it's worth a lot!!!
