Frequently asked questions
Does the TW radius matter?
Yes. The ABS sensor reads the disc at a defined radius. The 180 mm disc has a TW radius of 58 mm; the 203 and 220 mm discs have 70 mm (Rohloff 2026 price list).
Can I use this disc on a bike without ABS?
It is designed for ABS systems. Without ABS a standard Rohloff 2.0 mm rotor is the simpler choice.
Will a normal 6-bolt ABS disc fit?
No. Rohloff special brake rotors are required to ride a SPEEDHUB 500/14 with disc brakes: they use the hub's 4-bolt mount (65 mm bolt circle), not the usual 6-bolt or Centerlock standard.
