Massive castle, but still handy.

I bought my bike to shopping, or the occasional visit to the university to secure this castle. Of course, I compared before buying different models and have eventually resorted to the above model, as weight and handling are in a very good ratio. I bought the castle in a length of 85cm, this is sufficient in my opinion for the common "connectivity" of. However, it can quickly lead to problems in thicker trees or other objects wider.
So if you often chaining his bike to unconventional items that are not intended for bicycle security, should perhaps resort to the variant in 110cm. The castle is difficult, an estimated 2 Kg, can be but still very good store.
I transport it in the bike basket or hang it around the handlebars. For the road bike is certainly not the right thing for a city bicycle with basket wonderful. Even for people who are traveling with bag or backpack and can store the castle is a good choice. I leave my bike since I own the castle safely back.
