A trusty trail guide.
When dropping into your favorite flowy run, it's nice to know you've got SRAM Guide RS (B1) Disc Brakes along for the ride in the event of an unexpected mid-trail moose sighting or the perfect #autumncolors photo op. The Guide RS utilizes SRAM's Timing Port Closure, with a sliding cup seal and port mechanism that provides immediate actuation with a light pull action. The Swinglink lever facilitates powerful modulation, with a proprietary cam shape that's claimed to eliminate the jarring on/off feeling found in other disc brake systems so you won't get thrown over the bars when you mash on the brakes in front of that moose. As an extra bonus, the lever features Reach Adjust to quickly personalize your setup.
These brakes feature SRAM's new S4 caliper with Bleeding Edge design that updates the fluid and bleed routing for easier brake maintenance, with a bleed adapter plug that seals off the system from air and dust. The new caliper also boasts SRAM's Heat Shield technology, which consists of stainless steel shields that buffer the connection between the pad and caliper body to reduce head transfer to the hydraulic fluid and reduce its temperature by a claimed 20-degrees Celcius under heavy use.
Note that the Guide RS Disc Brake comes in either front/left or rear/right variants, with included lever and caliper configuration. It's compatible with SRAM's Centerline Rotors (sold separately) and uses DOT 5.1 fluid. Additionally, the Guide R is Matchmaker and Matchmaker X compatible, meaning you can run multiple controls off one lever clamp for a more streamlined set-up.
