Mountain bikers and e-bike riders, these JUIN TECH DB1 hydraulic disc brakes are serious stopping power at an amazing price! This complete set includes everything you need for both front and rear wheels: two dual-piston brake calipers made from forged aluminum with CNC precision, two 160mm stainless steel rotors (made in Taiwan with Japanese materials), two brake levers, all necessary postmount adapters and bolts, hoses (850mm front/1450mm rear), brake pads, and torx screws. The dual-piston design provides consistent, powerful braking with easy adjustment to get them dialed in perfectly. They use non-corrosive mineral oil that's more stable and environmentally friendly than DOT fluid, with better performance in varying temperatures. The red finish looks sharp on any bike, and the quality construction is evident in every component. Whether you're building up a new e-bike or upgrading the brakes on your current mountain bike, this complete set makes installation straightforward. The stopping power is impressive - plenty of modulation for technical descents and instant power when you need it most. For e-bike riders dealing with higher speeds and weights, these brakes provide the reliable stopping power you need for safe riding. The value is incredible compared to more expensive brand-name options, and the performance stands up to much costlier brakes. If you're looking to upgrade your bike's braking performance without breaking the bank, these JUIN TECH hydraulic brakes deliver professional-grade stopping power at a fraction of the cost of big-name brands. They're one of those component upgrades that completely transforms how your bike rides and handles!
