SRAM again raises the bar on rear derailleur performance with the Apex rear derailleur. The Apex WiFLi rear derailleur represents the same design philosophy that has delivered our best in class products for the road market. The SRAM Apex WiFLi rear derailleur lengthens its cage and gets a slight variation in geometry to accommodate an 11-32 cassette. The range of gears is wider than the standard triple chainring system and saves a significant amount of weight. Features also include our precise Exact Actuation ratio that offers the widest range of adjustment coupled with a precise geometry to create market leading 10-speed performance.TechnologyEXACT ACTUATIONWhen we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement) for 10 speed rear shifting. EA helps to simplify/stabilize the uneasy act of balancing rear derailleur hanger design, tight cog spacing and exact cable tension. The result: the easiest index shifting system to set up and it stays that way. WiFLiSRAM's WiFLi technology accommodates a wider range of gears than a standard short-cage road derailleur. Compared to a triple chainring setup, it provides faster shifts and significant weight savings.Specifications for SRAM Apex WiFLi Rear Derailleur• MATERIAL: Alloy outer cage / Steel inner cage• WEIGHT: 210g - Mid cage• CAGE SIZES: Mid cage• FINISH: Jet black gloss / Alpine white• MAX TOOTH: 32T• TECHNOLOGY HIGHLIGHT(S): Exact Actuation / WiFLi

It takes a degree of passion for the sport that can’t be faked to fully appreciate SRAM RED. It was created to blur the boundaries between machine and athlete. The SRAM RED rear derailleur was designed with our Exact Actuation technology for precise, efficient shifting. Carbon fibre, titanium, and ceramic bearings complete the spec. The result adds to its legacy as the heart of the purest groupset for the pursuit of cycling excellence.TechnologyAeroGlide PulleysNew tooth pulley design with a sound damping effect for a super efficient and silent ride experience. Bottom and top pulleys benefit from this feature.EXACT ACTUATIONWhen we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement) for 10 speed rear shifting.

The SRAM RED eTap rear derailleur executes shifts the instant you demand it, with military precision. Wirelessly. It’s easy to set up, clean in appearance and delightfully uncomplicated. Mechanical necessities such as a carbon pulley cage, ceramic pulley bearings, and anodized alloy artfully blend with proprietary electronic advancements to deliver a shifting wonder.TechnologyAIREAUtilizing 128-bit encryption, eTap shift signals are transmitted and received in accordance with SRAM’s proprietary wireless protocol known as AIREA. Each time an eTap groupset is paired, a new encryption code is generated and assigned to the components in this group to ensure complete shifting security.eTAPAll of the underlying tech in our new SRAM RED eTap groupset such as wireless shifting, advanced battery power management and mechatronics technologies are all meant to serve one ultimate purpose, to facilitate the most intuitive and consistent shifting available. This shift logic is called eTap. Right lever makes it harder, left lever makes it easier, both levers shift the front derailleur. Simple, unmistakable, and intuitive.EXACT ACTUATIONWhen we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement) for 10 speed rear shifting.
