No hay mucho que decir la marca que reconoce me gusto mucho el candado y como quedo solo siento que es un poco pequeño por lo que no sé de donde podría agarrarlo por el tamaño pero por lo demás tiene muy buena calidad y estética las lleves y todo si lo recomiendo.

Edit 1: esta muy pequeño le batallo mucho para asegurarla de algun lugar ni de broma se puede hacer lo que sale en una ilustacion de como asegurar la bici a lo mejor en una de niños si pero en una de montaña 27.5 no. Por lo demas sigo pensando lo mismo buena calidad y muy seguro.;

Good quality lock fits securely in the holder. I chose this model because it came with a cable lock to secure my quick release wheels. The shackle is just barely long enough to go through my frame though and will not fit around your wheel + frame together. If you are locking your bike to something thicker than 2.5 inches in diameter you will need to choose a different model.;

If using the lock without the cable it is basically impossible to get the U around both frame and tire of my bike (which is a fairly typical low-end mountain/street bike). The lock itself seems to be of decent quality lock mechanism moves smoothly.;
