Why do so many bike light manufacturers assume every cyclist is riding with the same handlebar size, completely disregarding the fact that many of us are running wider or narrower bars? Whats the best way to determine the correct bike light for my specific handlebar size, considering factors such as clamp size, light positioning, and overall visibility? How can I ensure that my light is securely attached and wont slip or move around during a ride, especially on rough terrain? Are there any specific brands or models that cater to different handlebar sizes, or am I forced to rely on universal mounts that may not provide the best fit?
