the finish of the article is well valued on commercial images of the Trelock company. Once in hand, so it was a little disappointing. But hey, it's a bicycle lock, not a gem! Effective mass read on the scale of household: 862 g, transport support included. The support is designed to attach to the bottle cage location. Hardware provided and necklaces to dock elsewhere on the frame. A tiny document called "level 3" is provided and allows the manufacturer to limit its liability in case of disaster. The test Fub 2013 grants the "level 1". I hope it's worth it because the appearance of quality riveting is not reassuring lot.
