summary : new disc rotor that mounts to where the sprocket usually mounts to on a REAR mag wheel to convert to a FRONT disc wheel OR have you heard that joke - how many moped companies does it take to make a rotor?
rotor thickness - 3mm
Using the EBR hydraulic fork and wheel perfectly centered, here's a reference guide to space out the rotor for each type of wheel + caliper combination in order to clear the caliper with the wheel and line up the rotor with the caliper brake pads.
Use 3/4" spacing between bracket and caliper (2x 3/8" NAZ aluminum spacers)
2- EBR + Tomos caliper
Use 1/4" spacing between wheel hub and rotor (8mm or 5/16 nut)
Use 1/8" spacing between EBR mounts and caliper (2 washers)
3- EBR + Grimeca caliper
Use 1/4" spacing between wheel hub and rotor (8mm or 5/16 nut)
Use 3/8" spacing between EBR top mount and caliper (6 washers)
Use 1/8" spacing between EBR lower mount and caliper (2 washers)
1- EBR + GOLD caliper + NAZ Bracket
Use 1/2" spacing between bracket and caliper (3/8" NAZ aluminum spacer + 2 washers)
2- EBR + Tomos caliper
Use 1/8" spacing between wheel hub and rotor (2 washers)
Use 1/8" spacing between EBR mounts and caliper (2 washers)
3- EBR + Grimeca caliper
Use 1/8" spacing between wheel hub and rotor (2 washers)
Use 3/8" spacing between EBR top mount and caliper (6 washers)
Use 1/8" spacing between ERB lower mount and caliper (2 washers)
C- GRIMECA 3 or 5 star vintage wheel:
1- EBR + GOLD caliper + NAZ bracket
Use 3/4" spacing between bracket and caliper (2x 3/8" NAZ aluminum spacers)
2- EBR + Tomos caliper
Use 1/4" spacing between wheel hub and rotor (8mm or 5/16 nut)
Use 1/8" spacing between EBR mounts and caliper (2 washers)
3- EBR + Grimeca caliper
Use 1/4" spacing between wheel hub and rotor (8mm or 5/16 nut)
Use 1/8" spacing between EBR mounts and caliper (2 washers)
TIP: If you're building a race moped and need a new set of wheels + front disc brake set up, buy the RAZZEELICA 3 star grimeca wheels wider than the BERNARDI 5 star chinese wheels.
