The Cygolite new Universal Handlebar bracket is a bolt on hard mount for the Magicshine light for those who do not like O ring mounts.
The P/N is 08-2213HM and the kit includes the plate that mounts on the headlight and the handlebar mount with all parts needed to fit handlebars from 25.4 to 31.8mm at the stem clamp area so it is basically a universal fit for most handlebars.
The light mounting plate clears the power cable on the lighthead fine but does not engage the strain relief on the lighthead wire. I wonder about the strain relief effectiveness anyway as it can slide on the wire I have noticed.
The handlebar mount is installed rotated about 90 degrees from the normal position due to the Magicshine light having it's mount on the bottom while the Cygolites have the plate mounted on the back of their lights.
