Juin Tech ETF 4-Piston Flat Mount Hydraulic Brake Calipers 160mm E-Bike Black

Juin Tech ETF 4-Piston Flat Mount Hydraulic Brake Caliper Set 160mm - Adapter-Free Rear Mount 

Bullet Points:

• UNMATCHED 4-PISTON POWER: Experience elite stopping performance. The Juin Tech ETF features a powerful quad-piston design that delivers massive braking force, superior modulation, and precise control—making it the ultimate upgrade for E-Bikes, Gravel bikes, and high-performance Road cycling.

• SLEEK ADAPTER-FREE REAR MOUNT: Achieve a clean, pro-level aesthetic. The rear caliper is designed for Direct Mount (Adapter-Free) installation on compatible flat-mount frames. This eliminates the bulky adapter, significantly reduces weight, increases structural rigidity, and minimizes the chance of brake squeal.

• PURE HYDRAULIC & MINERAL OIL SYSTEM: Enjoy the smooth, consistent feel of a fully hydraulic system. Engineered for non-corrosive, stable mineral oil, these calipers provide consistent braking pressure under all conditions and are much easier to maintain and bleed compared to DOT fluid systems.

• OPTIMIZED 160mm CONFIGURATION: This set is precision-engineered for the modern 160mm rotor standard (Front 160mm / Rear 160mm). It’s the ideal setup for maximum heat dissipation and reliable stopping power on demanding descents and heavy-duty rides.

• PREMIUM CNC MACHINED CRAFTSMANSHIP: Meticulously CNC-machined from high-strength aluminum alloy. The ventilated body design ensures excellent cooling during long descents. Available in 6 stunning anodized colors (Black, Red, Blue, Green, Purple, Gold) to perfectly match your custom build.

  The Ultimate Braking Upgrade: Juin Tech ETF 4-Piston Fully Hydraulic Calipers

  Elevate your ride with the Juin Tech ETF 4-Piston Flat Mount Hydraulic Brake Caliper Set.

  Specifically designed for riders who demand the highest level of performance and a clean, minimalist aesthetic, these calipers represent the pinnacle of aftermarket braking technology for Road, Gravel, and E-Bikes.

  Why the 4-Piston Direct Mount Design?

  Most standard calipers rely on a dual-piston setup and bulky rear adapters.

  The Juin Tech ETF breaks the mold with its Quad-Piston (4-Piston) architecture, providing significantly more surface area for braking force and better modulation.

  Furthermore, the Adapter-Free Rear Mount design allows the caliper to sit closer to the frame, improving power transfer and creating a "hidden" integrated look that is highly sought after by enthusiast builders.

  Mineral Oil Stability & Reliability

  The closed hydraulic system uses Mineral Oil, which is stable, doesn't absorb moisture, and won't damage your bike's paint. This ensures a firm lever feel and consistent performance season after season with minimal maintenance.

  Lightweight & Efficient Cooling Every gram counts. By utilizing CNC-machined aluminum and eliminating the rear adapter, this set offers a substantial weight-to-power advantage. The body is engineered with cooling fins to dissipate heat rapidly, ensuring your brakes remain responsive even on the longest, steepest alpine descents.
