Thud, thud, ding

Love the look and feel of this bell BUT there is an issue for me.
It is mounted on my drop bar gravel bike so sometimes on chunky trails.
When flicking the hammer with my hand off the bar the result is not always a robust ding.
The hammer fails to strike the chime.
It does work as expected with a more deliberate press but in some scenarios there is just not enough time to do that.
Wondering if there is an adjustment that can be made or perhaps one of the other models would work better for my use case.
Otherwise it is a great looking bell with a substantial tone.

Meh

Expensive for what I have. The spacers did not work. I had to dig around my shop for a proper spacer. $40 including shipping. I don’t find good value for what I paid.

bell

not loud enough! I will have to buy one to replace this....

Great service

Everything was excellent!

Nice Bell Sound

Slim profile and nearly invisible to others, until it rings and the group is trying to figure out who has a bell.

1 2 3

"RE-ENGINEERED DESIGN FOR PERFORMANCE AND LONGEVITY"

Subtle, until you strike it.

Every feature is fine-tuned for clarity, durability, and effortless installation.

WAVETEK

The innovative Oi Prima WAVETEK hammer delivers a louder, longer-lasting, and more consistent chime. The subtle wavelike motion creates a crisper, clearer tone that rings at 80+ decibels.

REFINED AESTHETIC

Every detail is meticulously considered. From tapered edges - inspired by the aerodynamic intake of a jet engine - to the minimalist silhouette and intricate laser etching.

ROBUST BUILD

The hinged clamp system makes installation quicker, easier, and secure whilst the bell's spring remains hidden within and can’t be overextended for a cleaner look that is engineered for lasting strength.

BEAUTIFUL SOUND

Loud enough to cut through traffic and trail noise, but tuned to be pleasant. The improved hammer and striking surface work together to produce a crisp, clean and considerate sound.

‘It's very loud.
It's very good-looking.’
