• Forged MONO-BODY one-piece caliper design is lightweight and rigid
• The flat-mount caliper is designed for rear wheel use and comes with an adapter to flip between 140 and 160mm rotors
• Oversized 22mm ceramic pistons optimised for heat insulation, low weight and stiffness
• A 10% increase in pad clearance reduces the chance of rotor drag
• Resin compound aluminium radiation fin pads improve heat dissipation
• Separate bleed port and valve screw for improved bleeding process
• Manufacturer claimed lever weight: 350 grams (for a pair of levers – this listing contains just the left lever)
