New for 2018. The IQ-XS has similar styling to the IQ-X with a machined and anodized aluminum housing.
Available in either black or silver anodized finishes. It has daytime running light, and automatically switches between daytime and nighttime modes. 70 lux.
The IQ-XS ships with its own highly adjustable mount, and is compatible with other Busch & Müller headlight mounts. For most applications the included mount will work. For bikes with limited clearance under the bottom headset cup or with cantilever brakes, use either the CYO or Thorn mount listed below.
The IQ-XS is NOT reversible and cannot be used in "upside-down"(i.e. hanging from the mounting point, as it might be on a front rack) orientation.
