With this I can lock up all MTB components: saddle, both wheels and then is still room to make it to wrap around a pole. I use it as an emergency lock, if I still need time to jump somewhere for 10 seconds on a tour to buy something. Generally, it is of course not suitable for backing up expensive MTBs. Setting a specific combination of numbers is easy. On and locking goes smoothly. I like it, am positively surprised and recommend this product.
