Pros and cons
Knog Oi Luxe
Pros
- Sleek, unobtrusive design — visually almost disappears on the bar
- Two clamp sizes (22.2 and 31.8 mm) plus a carbon-safe version
- Long singing tone that works well on quiet cycle paths
- Anodised aluminium feels premium and resists corrosion
Cons
- Not loud enough for heavy traffic or tourists who refuse to move aside
- Tiny T25 torx bolt requires the right key during installation
RockBros Loud Bell
Pros
- Around 95 dB — by far the loudest bell in this comparison
- Well under 10 euros — cheaper than almost every competitor
- Aluminium housing resists rain and mud better than painted steel
- Fits both 22.2 and 31.8 mm bars via an included shim
Cons
- Tone is harsh and tinny — no musical sustain
- Quality control is inconsistent — some units rattle out of the box
