The Trelock BC 580 is a serious chain lock built for serious bikes. With a 9 mm hardened steel chain and a high 15/18 security rating, it delivers strong, reliable protection for urban use and longer parking times.
When you leave your bike outside, you want confidence – not doubt. The Trelock BC 580 offers exactly that.
Its 9 mm hardened steel chain provides robust resistance against cutting attempts, while the integrated hardened steel padlock features a cylinder protected against drilling. With a 15/18 security level in the TRELOCK scale, this model is designed for demanding riders who need dependable protection.
The durable neoprene sleeve prevents scratches on your frame and keeps your bike looking sharp. With 110 cm length, you have enough flexibility to secure the frame and wheel to fixed objects in the city.
This is not a lightweight “just in case” lock – it’s a proper security solution for daily urban riding.
