RockyMounts Carlito U-Lock

A security level 4 rating is designed for quick stops and low-risk environments, such as running into a coffee shop or a short errand. It is intended as a deterrent for opportunistic theft rather than long-term parking in high-crime areas.

The shackle dimensions are 75mm x 127mm. While it is compact and fits easily in a pocket, you should measure your bike's frame tubing and the typical racks you use to ensure the opening provides enough clearance.

The silicone overmold serves two purposes: it provides a soft, grippy texture that makes the lock comfortable to handle and, more importantly, it prevents the metal shackle from scratching or dinging your bike's paint finish while you are locking up.

The Carlito U-Lock includes three keys. We recommend keeping one on your primary keychain, one in a secure spot at home, and giving the third to a trusted friend or family member as a backup.

At 395g, this is one of the lightest U-locks on the market. It is specifically engineered to be unobtrusive, making it easy to carry in a jeans pocket or a small bag without feeling weighed down during your commute.
