SRAM Level TLM Mountain Bike Disc BrakeThis championship-winning disc brake is ready to take all the abuse you want to give it out on the trails. It puts proven SRAM braking performance at your fingertips thanks to its sleek, lightweight design that's specially optimised for XC and light trail use. Additionally, it delivers power and modulation via its robust alloy lever blade, DirectLink actuation, DOT 5.1 fluid and a two-piston monoblock caliper. Furthermore, this superb design provides you with superior heat management for consistent, fade-free braking ride after ride.Features: Lever Material: Forged Aluminium Hardware Material: Stainless Steel Use: MTB, XC Caliper: 2-piston Fluid: DOT 5.1 Adjustment: Tooled reach adjust System: Open system Pad/Holder: Top loadingTechnologies: Bleeding Edge: Bleeding Edge technology makes bleeding brakes quick and simple. An updated fluid path and bleed porting make it easier to push fluid through the caliper. A dedicated bleed adapter plugs into the bleed port and seals the system to minimize air contamination and fluid loss. DirectLink: 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. We found that in our 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 back-pressure relief, which produces dependable braking power and consistency. Heat Shield: The stainless steel heat shields breaks the thermal connection between the pad and caliper body, reducing caliper fluid temperature by about 20C even in the most extreme testing conditions. Lever Pivot Bearings: Precision sealed bearings at the lever pivot enhance the clean, crisp lever actuation and consistent, light, one-finger feel. MatchMaker and MMX Compatible: Save weight and clutter on the bar with Matchmaker. It holds Avid levers, SRAM triggers, and various RockShox controls, all with one tidy, light, clamp--a dream come true for handlebar component footprint conservationists the world over. Available in two versions: Matchmaker X integrates the RockShoxXLoc and is compatible with XX and X0 brakes. Standard Matchmakeris also available and works with any split-clamp design and RockShox PushLoc. PiggyBack Reservoir: The brake fluid reservoir on SRAM's latest lever design is optimized 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—so you can switch your levers on the handlebar and run them moto without hassle. 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 pressurizes 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.Buy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

The PiggyBack Reservoir offers a simple, failsafe way to manage brake fluid, and also allows for ambidextrous lever placement—so you can switch your levers on the handlebar and run them moto-style without hassle PURE Bladder: SRAM’s new brake lever design includes a reshaped bladder, called Pure, 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 back-pressure relief, which produces dependable braking power and consistency Reach Adjust: Brake lever fit and feel is a personal thing. Riders have individual positioning preferences, as well as unique hand sizes and finger lengths. Reach Adjust makes it easy to adjust your lever for maximum one-finger control for everyone.SwingLink: Squeeze a new SRAM brake lever and you notice it immediately. Less deadband. More positive pad engagement. A new cam system requires less lever throw to push the pads toward the rotor. That’s great, but there’s more to perfect braking performance than just power. You need control. Many brake systems minimize deadband—but at the cost of modulation. SwingLink solves that with its special cam shape. When the pads contact the rotor, power is modulated, avoiding that “on/off” brake feel. It’s the perfect balance of power and precision.TPC Plus (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 pressurizes the system.

SRAM G2 RS Disc BrakeAll set for hitting your local mountain bike (MTB) trails, this hydraulic disc brake is equipped with a robust aluminium lever body and a forged aluminium caliper, which makes it ready for the most demanding of trail adventures. Another highlight is its tool-less adjustable lever reach that allows you to easily set it up to match your hand size or riding style. This makes it comfortable to pull as you dive into corners and drops at speed, while also keeping your momentum flowing. Coming complete with SRAM's Bleeding Edge technology, this model also allows for simple DOT 4 fluid installation and maintenance when required.Hydraulic Disc Brake with SwingLink TechnologyWe spend a lot of time obsessing over feeling, and SwingLink technology brings SRAM's best research and development to life. The G2 RS offers riders the joys of SwingLink — getting brake pads to the rotor fast, then moderating pressure with smooth modulation. It's one small movement for your finger, one monumental upgrade to your braking.Power Reserve GeometryYour fingers pull in a straight line, but brake levers move in an arc. Bottom line: Your fingers typically want to slip off the ends of the levers as you pull. SRAM designed all of its brakes with the industry's lowest X Factor (that's the distance from the centre of the handlebar to the centre of the lever's pivot). That reduces the lever's inward travel, creating an arc that's closer to your fingers' natural motion and more power is delivered to the brake lever. And, the cool part is, every SRAM and Avid brake lever has it.Bleeding EdgeWith this new caliper fluid circuitry, the bleed port has been moved to the bottom of the caliper, and all four piston bores can communicate. This way, during bleeding fluid naturally fills the caliper, resulting in an easier, more consistent bleed.S4 Light-Weight 4-Piston CaliperThe all new S4 Caliper features four Machined and Moly-coated aluminium pistons for consistent rollback and easy set-up, Heat shield insulation and Bleeding Edge porting and adapter technology for easy bleeds.SwingLinkSqueeze a SRAM brake lever and you notice it immediately.
