I bought a Hub Light for V- Brakes (SL100), but I have disc/roller brakes. Is it possible to upgrade my Hub Lights to fit disc/roller brakes? Mille Stech Jensen September 21, 2017 12:33 Updated Yes, you can buy two new brackets and be ready to go. Here are the links for a bracket For front & for rear. But be aware that even with the extended bracket the light will only be possible to mount as long as the disc brake is max. Ø160 mm. Related articles How much light does the Hub Lights emit? How many lumen does NOVA have? Why is it important to know the brake type? I just bought a new bicycle with roller brakes and would like to move my Hub Lights for V-brakes (SL100) to this.
