【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
وصف
