I am quite satisfied with this product that has the good idea to be easy to carry, flexible and durable. In terms of weight, all depend on the model you will take, but it does not feel on the bike.
The anti-theft exudes quality and you really feel that it will not wear quickly. It comes with a set of two keys, it is possible to re-providing the ABUS code.
The transport holder can be fixed instead of the gourd or elsewhere through the supplied velcro. It's a choice I have opted for fixing instead of the gourd, with screws.
In short, a product I can only recommend as it is well thought out and good quality.
