Large-sized ring lock, includes the lock and mounting parts. - Model: JC-056CLB - Size: Large - Included: Key, mounting parts - Colors: Black, Silver I bought this a few days ago and tried to install it, but it didn't fit my bicycle, so I'm selling it. It's new and unused, but I did try to attach it once, so there's a crease on some of the parts. Please be aware of this.
