Shimano seems like this, the shift is tight and light and tight. Brake lever is also a set, I think that it is a bargain product. In addition, since the V brake is not set at the beginning, attention and change are necessary for that.
Although EF 51 is better in COSPA, purchase this here because it is attached to the bicycle around there such as cycle shop and town and I do not like making toy. Although I do not have detailed instructions, I think that anyone can install it if I observe it well. Just handle space is taken quite a bit.
