Be noticed with the Portland Design Studio King of Ding II Brass Bell. With design harkening back to the days of riding fender-adorned steel bikes in tweed suits and elbow patches, this classy brass bell emits a bright, crisp sound to let fellow road users, wandering pelicans, and assorted wildlife know you're heading their way. Consisting of a solid brass bell, brass striker, and alloy mounting system, this bell affixes easily to bars ranging from 22. 2mm to 25. 4mm for added safety and classy style on any bike.
