QUAD-PISTON MAXIMUM POWER: Elevate your braking performance with the Juin Tech GTF4. Featuring an advanced 4-piston (quad-piston) closed hydraulic system, these calipers deliver immense stopping power, superior modulation, and unmatched control for aggressive Gravel riding and steep descents.
FLAT MOUNT SPECIFIC: Precision-engineered for modern Road, Gravel, and Cyclocross (CX) bike frames and forks equipped with the Flat Mount standard. Offers a sleek, aerodynamic profile while housing a heavy-duty braking mechanism.
SEAMLESS HYBRID UPGRADE: Get the power of a 4-piston hydraulic setup without the massive cost of replacing your existing mechanical drop-bar shift/brake levers. The GTF4 uses your standard brake cables to actuate the hydraulic system effortlessly.
SUPERIOR HEAT DISSIPATION: The 4-piston design utilizes larger brake pads and offers better thermal management than standard 2-piston systems. Enjoy consistent, fade-free braking performance even on long, demanding downhills or when carrying heavy touring loads.
PRE-BLED & READY TO MOUNT: Forget about messy fluid bleeding procedures. The GTF4 calipers arrive pre-bled with mineral oil from the factory. The complete set includes Front and Rear calipers, pre-installed brake pads, and mounting hardware.
