Trivia that no longer applies: At one point this was the only bell available that fit onto a 26mm road bike handlebar sleeve, so we dubbed it Bell 26. Now all of our bells have the same clamp (fits 22.2mm to 26mm), so it would make sense to rename this, but...we all know it as Bell 26, so we're not going to rename it. In any case....
....it's our only coily spring bell (as opposed to hammer-strike style), and I/Grant like it more than most others do. It's not as loud as the hammer-strike bells, and on a bumpy trail it rings itself. Big deal. It's loud enough, and the self-ringing—it's music! I like that it's easy to ring with a finger flick. To me it seems easier than the hammer strike, which requires you to pull a trigger.
The clamp is the same as on all of our clamp-on bells. It fits 22.2 to 26mm bar diameters, and it's OK to use a single wrap of bar tape to protect bare metal.
The accompanying pictures show a few reasonable possibilities. (Not shown: around the stem quill, around a frame pump, etc, etc, ...)
The best way to rig it: On the sleeve of the bar (or over the twine). Use slip-jaw pliers to squeeze the clamps together--it just makes it easier to use the screws.
NOW, also available in copper or silver polished alloy in addition to brasssss.
Also note: The dome is rivetted to the shaft; the shaft itself is threaded. You can unscrew the dome-with-shaft from the clamp and THEN, if you have a threaded stem or headset spacer, you can thread the shaft-and-dome directly into it, thereby end-arounding the clamp.
NOTE: If you have the bad habit of storing your bike outside, Do Not Do It! Bring that bike inside, please! Your trusty little bike and all it's metal parts are corroding little by little by being stored outside, exposed to the mist, dew, fog, rain, snow, elements. Especially if you live near a salty, moist, humid ocean environment like Kona or the Sunset. The tiny little spring part of this Bell can corrode and break even after a few months of being stored outside. But this bell will last for many many years if you keep your bike inside most of the time. A Riv Staff rider lives right by the ocean and stores his bike inside most of the time and his bell is over a decade in age and the spring is still going strong. And he cleans his bike a lot, wipes off the corrosive sweat, so be sure to clean off your bike maybe once a year or so, too. Your bike and it's many little and big metal parts will thank you. Not to mention that your bike can easily go missing even if it's locked up to the fence in the backyard...
