Stromer uses brakes from TRP (Tektro Racing Products). Older models also had brakes from Shimano (Deore, SLX, XT) or Magura MT2/4/5E). All brands use non-corrosive mineral oil as brake fluid with an elevated boiling point of 270 °C and low viscosity for good flow behavior. Sources of supply: EN | CH
