This superb disc brake levels the playing field with power and reliability stuffed into a lightweight package. Additionally, its strong and reliable aluminium construction makes it ideal for tackling the trails and offroad riding conditions. This is a perfect choice of upgrade or replacement for your old or worn-out existing model. Technologies: Direct Link: SRAM's DirectLink lever design produces a solid, positive feel the second you squeeze the lever to engage the brake. It offers a no-nonsense solution to give you precise control. DOT 5.1: Heat is an enemy of any brake system, so advancements in heat management mean advancements in your ride. SRAM found that in their systems DOT 5.1 takes almost three times longer to boil than DOT 4, thus allowing flawless, fade-free performance in even more extreme conditions. Expandable Bladder: SRAM's new brake lever design includes a reshaped bladder that helps regulate and reduce air bubbles. The bladder is specifically shaped to evacuate air from the lever and push the fluid exactly where it's needed. The result is improved backpressure relief, which produces dependable braking power and consistency. PiggyBack Reservoir: The brake fluid reservoir on SRAM's latest lever design is optimised for both performance and ease of use. The PiggyBack Reservoir offers a simple, failsafe way to manage brake fluid, and also allows for ambidextrous lever placement. Timing Port Closure: A hydraulic brake's timing port is the connection between the reservoir and the master cylinder bore. When the lever is squeezed, a cup seal passes this area and closes the port, which pressurises the system. SRAM's new timing port closure system features durable seals and an ultra-smooth cylinder bore finish, producing dependable braking power and consistency.
