A 145mm Bombers bit, loose ring Ultra Comfort Lock-Up. Used for about a year and stored. It's a used item, so there is some rust, but this is a characteristic of this bit and it can be used without any problems. It is mainly used for horses that tend to lean, are difficult to control, tense up, or get behind the bit. It's a large size. If it's too big, you can adjust it by adding bit guards. I'll include a pair of 5mm thick bit guards (photo 6) as a used item, so please try them. This pair will reduce the bit's length by 1cm. According to the Bombers website, you can also use another set of bit guards. Based on my own experience, it was effective for horses that overreact to the bit, sometimes resist, but still need a firm hand. I think it's good to experiment with different equipment, not always using the same one. If you work with many horses, this bit is worth having.
