Supernova Universal HBM Handlebar Mount – 35 mm
The Supernova Universal HBM for ø 35 mm handlebars is a hinged aluminium handlebar mount for Supernova front lights. Use it when the light should sit on the bar instead of the fork.

Why a handlebar mount?
Hinged clamp. The clamp opens for fitting and mounts on the left or right side of the stem.
ø 35 mm clamp. Made for 35 mm handlebars; the same mount is also made in ø 31.8 mm.
Anodized aluminium. A solid, matt black mount that holds the light securely.
Original Supernova part. For almost all Supernova front lights – only the special HBM versions and the Airstream battery light have their own holders.
Light on the bar, not on the fork
Not every fork has a mounting point for a light, and some riders prefer the light higher up, where it is less exposed to mud and spray.
Supernova states that the Universal HBM needs a stem width of at most 44 mm and a free clamping area of 12 mm on the bar. For the Airstream battery light, choose the Airstream HBM.
Who is it for?
- Bikes with 35 mm handlebars. And a Supernova front light.
- Riders who want the light on the bar. Rather than on the fork crown.
- Replacement. A lost or damaged mount.

Send us a photo and we will tell you what you need. Supernova was founded in Germany in 1997. It started with a headlight its founder built for his own night training rides – after around 20,000 kilometres of riding in the dark, the company was born. Supernova lights are developed in Germany, and its top models are produced in Gundelfingen near Freiburg. The brand builds machined aluminium housings and lenses that put the light where you need it, and backs its lighting systems with a 5-year guarantee and at least 10 years of repairability.About Supernova
