Special Features

  • 【Upgraded 4-Piston Hydraulic Brake】The IV4's upgraded 4-piston design synchronizes oil pressure to deliver up to 685N braking force, outperforming standard 2-piston systems by 52%，with 8.1ft shorter stops at 30km/h. Ideal for downhill MTB, e-bike, fat bike, and enduro setups
  • 【Reinforced Ceramic Brake Pads】The IV4 hydraulic disc brake adopts reinforced ceramic-metal hybrid pads, offering a 75% increase in heat resistance compared to standard traditional resin pads. This minimizes fade during continuous braking and provides 95% noise reduction for a quieter, smoother ride
  • 【Stronger Yet Still Lightweight】With CNC-machined aluminum calipers and a reinforced lever body, the IV4 maintains high durability while weighing only 229g (front) and 241g (rear). Strikes the perfect balance between robust performance and manageable weight for aggressive riders
  • 【Optimized Hose Lengths】Pre-bled front brake hose: 850mm (33.5"), rear brake hose: 1550mm (61.0"), making it suitable for most trail, downhill, and e-MTB frame geometries. Please confirm your bike's cable routing before ordering
  • 【Mounting Reminder】Adapters are not included. Compatible with Post Mount (direct 160mm rotor installation). For IS or Flat Mount standards, separate adapters are required. Ensure compatibility with your fork/frame before installation.Reminder:Avoid squeezing the brake lever without a rotor or spacer in place to prevent damag

Description

The IV4 4-piston hydraulic disc brake set delivers exceptional stopping power and control, outperforming standard 2-piston systems with stronger, more stable braking force. Featuring ceramic-metal pads with aluminum alloy heat dissipation, it ensures quiet operation and reliable performance even on long descents. Lightweight yet durable, the IV4 is easy to install with pre-bled hoses for most MTB, e-bike, fat, and folding bikes.
