Don't let the small size fool you. Mirrycle's Thermobell is little, light and LOUD! This thermometer-topped bell displays both Fahrenheit and Celsius. It has a pivoting dinger and a dual size clamp so it fits any bar. Plus, its diminutive dimension and pivoting ringer let you mount it just about anywhere on your handlebars. A flick of your finger and the Ding! Ding! rings clear for all to hear.
