SRAM Apex 1 Rear Derailleur – Long Cage

Drop bar or flat bar, dirt or pavement, Apex 1 is ready to answer the call of the road with hydraulic disc brakes and the simple, quiet, easy to use, and very secure drivetrain – SRAM 1x. Apex 1 achieves each of these superlatives while delivering artful design at an unrivalled value. 

SRAM’s Apex 1 drivetrain provides the gear range and the shifting simplicity to let you simply go where you want. The Apex 1 rear derailleur makes that gearing choice a reality with clean, crisp shifts, thanks to SRAM’s X-Horizon geometry and Roller Bearing Clutch. 

Features

X-Horizon design reduces shift force, eliminates ghost shifting and chain slap.

Compatible with 10-speed and 11-speed SRAM 1x road systems.

With Cage Lock technology, wheel removal and installation are easier than ever.

Equipped with Roller Bearing Clutch

Large upper pulley offset automatically adjusts chain gap.

Long cage fits up to a 42 tooth cog.

Technologies

X-Horizon – The X-Horizon rear derailleur’s ‘straight parallelogram’ design limits all movement to the horizontal axis, which makes 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.

Exact Actuation – When 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/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. 

Roller Bearing Clutch – rear derailleurs 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. 

Cage Lock – With Cage Lock technology in the rear derailleur, wheel removal and installation-as well as chain installation-becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place. 

X-Sync – Sram X-Sync provides the highest level of performance and durability. The SRAM X-Sync tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync chain rings 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 drivetrain.
