OI Prima bell is a fine piece of jewelry, for my beloved MTB , It has a unique ring tone, that is sweet sounding and different from traditional bells. summoning pedestrians and trail hog's to move out of my way.
Nicer than the old design, large fits well on dropbar near stem (31.8mm). Cutout in clamp for hoses/cables could be a little bit wider, but still fits fine.
Kind of wish there was a optional guard for the bell part so you don't have to worry about loose hoses or bar bags dampening it.
I’ve always loved the low profile design of Knog bells. And now they are louder and more durable. What more could you ask for?
Doesn’t match the Knog hype.
Overall a ok bell for the price. Needs so work on the fit on the handbar.
