Hydraulic disc brake set with a 4-piston aluminum caliper and mineral oil system. Arrives pre-bled with front (1100mm) and rear (1600mm) hoses — rotors not included.

• Mineral oil only - not compatible with DOT fluid. Do not mix fluids. Safer to handle during bleeds and won't damage paint or seals on contact.
• Hose lengths: 1100mm front / 1600mm rear - fits most standard MTB and e-bike frame geometries without a re-bleed on arrival. Frames requiring longer lines will need a custom bleed after installation.
• Rotor compatibility: 140–203mm - works with 140mm, 160mm, 180mm, and 203mm rotors via IS or post mount adapter. Adapter not included — verify your frame and fork mount spec before ordering.
• 4-piston caliper - CNC-machined aluminum body with 4×18mm composite pistons. Self-adjusts as pads wear.

What's in the box:

• 2x brake levers (front and rear)
• 2x 4-piston calipers (front and rear)
• 2x pre-bled hoses (1100mm front, 1600mm rear)
