I will build some custom double-crown steel forks with twin disc mounts & oln of 120 or 135mm with a rear single speed disc hub. Just have to be careful I always drop the wheel in the right way round to avoid unscrewing. The tricky bit will be getting the same flex as my current Reynolds 531 tandem forks- they bend like springs, giving 1.5-2″ of stiction free suspension, taking out nearly all vibes.

My reason for doing this is heat dissipation/ fade prevention rather than overall stopping power. At present I have single 8″ rear disc and rim brake up front. I’m often using a full set of front pads on a single descent and sometimes getting rear fade & blackening the disc. My daughter rides the rear (stoker) seat on the tandem & is only 15kg at present. Things are going to get a lot worse, with her weight & if we add a trailer.

I use this on my motorized bike which has a fixie(ss) underneath because I needed a disc brake mount to attach a drive sprocket securely.

Good product

Thanks for thinking outside the box. I run a track geo SS/FG cross with 120 spacing and had I thought of this or knew it was an option, I would have went with disc brakes instead of canti’s. Next time, for sure.
