SRAM RED HRD Shift-Brake Control W/Flatmount Caliper

Awarded top honors by Germany's "RoadBike" magazine, SRAM's HydroR system provides unconditional braking.

If you believe in better performance then you should believe in hydraulic road (HydroR) brakes. Our award winning HydroR technology is the fulfillment of the promise of better braking, more control, and improved performance in all conditions. SRAM Red is delivering on the promise of braking confidence and security that brings speed control and stability to a new level.

Technologies

Connectamajig - Connectamajig is the coupling hose that makes initial set-up of hydraulic systems easy, fast and convenient. The intimidation of hydraulics is gone with a push and a twist; it's just that easy. Connectamajig allows for several disconnects and reconnects before a system bleed is required.

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.

DoubleTap - DoubleTap makes changing gears easier and faster, eliminating the cumbersome and awkward engagement associated with two-lever systems. DoubleTap handles up- and downshifts in one short, sweeping motion, with minimal effort and maximum comfort no matter where you are on the bars.

DoubleTap uses two pawls, one for holding the ratchet wheel, and one for transporting it up and down through the gear change. The pawls are arranged in a way so that they can leapfrog each other depending on how far, and with how much pressure, you push the shift lever.

With short, rapid taps the transport pawl (04) moves the ratchet wheel (02) up through the shifting range. Downshifting comes via a longer sweep of the lever (in the same inward direction you upshift, but to an ergonomically maximized 15 angle) with the holding pawl (03) and the transport pawl leapfrogging each other quickly and smoothly.

Location, Location, Location: DoubleTap's one-motion unidirectional levers (05) work flawlessly no matter what position you're shifting from. Its double-articulated design (01), which is completely separate from the brake pivot, is easily engaged from the hoods or the drops.

Unlike all other forward controls, DoubleTap also lets you pull the shift lever in against the bars so you can upshift while sprinting or attacking without giving up a firm grip. On DoubleTap controls, the brake and shift levers are completely independent, each operating with their own pivot points. This not only allows for the multiposition functionality, it also eliminates the risk of engaging brakes or shifters unintentionally-an unfortunate side effect of other shift/brake lever designs.

ErgoDynamics - Longer brake levers, independent reach adjust for the brake and shift levers, and optimized hood shape give riders of any size comfort and easy access to the controls.

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.

Yaw - The front derailleur cage rotates to maintain a consistent angular relationship with the chain. Yaw technology eliminates the need for shifter trim. As a result, shifts feel more direct, more precise, and combined with the new Red crankset and chainrings, delivers an unmatched performance advantage in front shifting.

ZeroLoss - ZeroLoss simply means, well, zero loss-when you push on the lever, for an upshift or down shift, the cable is engaged instantly-zero loss of movement. There is no middle-ground where you're waiting for the shift to come. Gear changes are instant and precise.

Reviews

SRAM Red "shifting snaps into gear superbly every time"

"In a world dominated by Shimano, it's good to be able to ride SRAM Red again. It's easy to forget just how slick SRAM's top-end groupset actually is. The Double Tap shifting snaps into gear superbly every time, and the speed with which you can ship across the block and the smoothness of the trim-free Yaw front derailleur are both marvels. Oh, and it's also the lightest groupset out there. Impressive." View Article
