SRAM Apex 1 11 Speed Rear DerailleurThe SRAM Apex 1 Rear Derailleur brings the simplicity of mountain bike gearing to your Road, Hybrid, Gravel or Cyclocross (CX) bike so you can go where you want. Compatible with up to a 42T cassette, it will help you tackle the toughest 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 cageCage Length/Type: Long cage fits up to a 42-tooth cogSpeed: 10 or 11-Speed SRAM Road drivetrainsClutch Options: Roller Bearing ClutchIntended Group: Apex 1x11Max Tooth: 42TPull: X-Actuation™Pulleys: Sealed cartridge bearingsCompatibility: Compatible with 10-speed and 11-speed SRAM 1x™ road systemsTechnology Highlights: Cage Lock™, Roller Bearing Clutch™, Exact Actuation™, X-Horizon™, X-Sync™Weight: 314gPart No: RD-APX-1-A1Technologies: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 place.Roller 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 precision.Exact Actuation™: When SRAM launched their road technology from scratch, they reapplied their mountain bike (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.X-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 gears.X-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.
