This is the most intriguing new bell anyone has ever seen. It fits on any 22mm handlebar just like a grip shift. It's great for bicycles that have one side of the handlebar free of shift levers (both sides can have brake levers): cruisers, town bikes with only rear shifting, kids' bikes. It is available in solid brass. The sound of the ring is very musical. The Grip Bell weighs 2.1 ounces. Fits handlebars with 22mm outside diameter.
