The Lezyne Classic Small bell is of a compact, classic shape constructed from highly-polished, high quality brass and mounted to a machined aluminium black base. The small brass striker provides a sharp, impressively loud ring when flicked, warning others of your presence. A simple O-ring attaches the bell to a variety of tube sizes and shapes while integrating cleanly with any bicycle. Weight is 21g and comes with O-rings of various sizes.
