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 securityeTAP - All of the underlying tech in the 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 intuitiveExact Actuation: When SRAM launched their road technology from scratch they reapplied their MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement) for 10 speed rear shifting. EA helps to simplify/stabilise 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 wayBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

The result is that the chain runs through the rear derailleur smoother and quieter than ever before.Features: Material: Carbon Cages, Carbon inner links, aero designed Titanium hardware Exact Actuation shifting provides fast, and accurate shifts More clearance with 28t cassettes thanks to a longer B-knuckle Medium cage (WiFLi version) compatible up to 32T cassette New silent shifting with optimised Aeroglide Pulleys with ceramic bearings New spring-fixed barrel adjuster New chain pulley cage adds precise chain management Titanium pinch bolt keeps a low profile while minimising weight Speed: 11-Speed Recommended Group: SRAM Red 11-Speed Weight: 145gTechnologies: AeroGlide Pulleys: New 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 Actuation: When SRAM launched their road technology from scratch they reapplied their MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement). Exact Actuation helps to simplify and stabilise 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 WiFLi (medium cage only): SRAM'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 savingsBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

SRAM Apex 1 11sp Rear DerailleurThe SRAM Apex 1 Rear Mech brings the simplicity of 1x Mountain bike gearing to your Road, Hybrid, Gravel, CycloCross or do-it-all bike, so you can go where you want. Compatible with up to a 42T cassette, it will help you get over the roughest terrain and the steepest climbs. Also, thanks to SRAM's Exact Actuation, X-Horizon technologies, you'll enjoy fast, precise and reliable shifting.Features: Material: Aluminium cage Speed: 10 or 11-Speed SRAM Road drivetrains Intended Group: Apex 1x11 Max Tooth: 42T Pull: X-Actuation Pulleys: Sealed cartridge bearings Technology Highlights: Cage Lock, Roller Bearing Clutch, Exact Actuation, X-Horizon, X-Sync Weight: 314gTechnologies:Cage Lock: With Cage Lock technology in the rear derailleur, wheel removal and installation—as well as chain installation—becomes faster and simpler. Just push the cage forward to create slack and lock it into placeRoller Bearing Clutch: SRAM's rear derailleurs with this technology deliver maximum drivetrain stability—even through the most punishing terrain. With Roller Bearing Clutch technology, derailleur bounce and chain slap are eliminated without sacrificing precisionExact Actuation: When SRAM launched their road technology from scratch they reapplied their MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement). Exact Actuation helps to simplify and stabilise 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 wayX-Horizon: This technology gives the rear derailleur a 'straight parallelogram' design, which limits all movement to the Horizontal axis, making ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gearsX-Sync Pulleys: SRAM'S 1X X-Sync pulleys and chainrings provide the highest level of performance and durability. Their tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. Their sharp and narrow tooth profile, as well as their rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-Sync rings are an integral part of the SRAM 1X drivetrainBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
