It's a SR Suntour DuoTrack but with all canti bits chopped off and repainted to match the frame.



The brake is fitted to a hole in the fork brace. It's pretty stiff so I'm not expecting problems. It's a similar concept to the Rock Shox Roubaix forks that were developed of off the Mag 21 series for roadbike use (mid to late nineties).
