Juin JuinTECH ETF 4-Piston Road Hydraulic Disc Brake Caliper: Flat Mount, 100% CNC Monobloc, for Hydraulic Road Levers, DOT Oil, 160mm (Black)

Description

• TAIWAN-MADE 4-PISTON POWER, MOTORSPORT-DERIVED: JuinTECH designs and machines the ETF in-house in Taiwan. The 4-piston layout spreads clamping force over a larger pad area for linear yet ferocious stopping power, even pad wear, and confident control you can trust on long, steep descents.
• 100% CNC MONOBLOC, NOT CAST, NOT BOLTED: Each ETF caliper is CNC-machined from a single block of European high-purity 6061 aluminum billet, not a low-cost cast-and-bolted two-piece body. The result is rock-solid stiffness, a flawless anodized finish, and a body engineered to move heat instead of trapping it.
• FULL-METAL PISTONS: HEAT MOVES OUT, NOT INTO FADE. Unlike phenolic/plastic pistons that push heat into the pads (causing glazing and brake fade), ETF's full-metal 7075 pistons channel heat into the caliper body so the whole caliper becomes the heat sink. Pair with JuinTECH RT01Z / RM01 rotors for a complete thermal system.
• MORE POWER, LESS WEIGHT, FULL HYDRAULIC: Just 75g (Mineral) / 79g (DOT) per caliper (140mm, no pads), lighter than premium 2-piston calipers yet harder-hitting. Full hydraulic caliper for hydraulic road levers: choose Mineral Oil for Shimano and Campagnolo systems, or DOT for SRAM. Not for mechanical (cable-pull) levers.
• SOLD AS ONE CALIPER, DP43 + SP43 PADS: Price is per single caliper (one wheel); order 2 for a full front & rear upgrade. Flat Mount, 140mm or 160mm direct. Replacement pads DP43 + SP43 (shared with GTP-4 / GTF-4, Shimano Saint pad shape). Zero-color-shift anodizing in Black, Red, Gold, Purple, Blue and Lake Green. Rotor not included. UNLEASH! NEXT LEVEL.

UNLEASH! NEXT LEVEL. JuinTECH brings automotive and motorcycle design philosophy to the bicycle: breaking physical limits through precision machining to take every rider to the next level. A relentless pursuit of the essence of mechanical physics and structure. That is what JuinTECH believes.
