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 Why is it important to know the brake type?
