The SRAM Guide Ultimate Disc Brake represents the utmost expression of braking power and lightweight design, standing atop its class with a new 4-piston S4 caliper, complete with a stainless steel heat shield for reduced brake fade on long descents. Tipping the scales at a feathery 360 grams (front brake with rotor, hose, clamp, adapter, all bolts), the Guide Ultimate Disc Brake is one of the lightest brakes on the market, made possible by its carbon lever blades and titanium lever hardware. In fact, the Guide Ultimate is approximately 80 grams lighter (for the pair) than the excellent Guide RSC, making it a worthy upgrade for riders seeking a lighter overall set-up and improved braking at high speeds. Standing as the defining achievement, the completely redesigned caliper serves up consistent braking every time you pull the lever, no matter if it's the top of the descent or the end of a swift downhill section. SRAM achieved this by creating the 4-piston S4 caliper, with small machined grooves that enhance rollback speed of the caliper to its original position. Another major improvement is the addition of a stainless steel heat sink, which reduces braking temperature by an astounding 20 degrees Celsius. Running cooler brakes is a must for downhill racers and trail riders seeking consistent braking on the descent, as brake-sapping heat compromises your ability to stop. Additionally, the location of the caliper's bleed port was revised to simplify bleeding, which is a common complaint of previous Guide Brakes. The new location allows fluid to flow from the caliper into the lever body, preventing tiny air bubbles from remaining inside the caliper after bleeding. The SRAM Guide Ultimate is available in a Front/left or Rear/right lever and caliper package, with compatible Centerline and Centerline X Rotors sold separately. Plus, it's Matchmaker X-compatible for integrating SRAM shifters and various RockShox controls from a single tidy clamp.

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
