Sleek, new, ultralight bar-end mirror easily attaches to drop and flat bars, making it perfect for all bikes. Constructed of aluminum and glass for durability and nearly distortion-free viewing, the BM-45 represents the height of handlebar mirror construction and design. Minimal projection from the bar means never having to sacrifice clean aesthetics for critical rear-view safety again. Weight-35g Lens size-45mm 3mm Allen key included
