SRAM APEX 1X12 Speed Groupset

Apex is the group that knows how to have a good time. Wide-range 1x12 gearing for gravel, bikepacking, adventure, casual cruises, and everything in between. Whether with wireless AXS or classic DoubleTap mechanical shifting, Apex provides smooth and reliable shifting, chain retention, and controlled and powerful hydraulic braking. Apex is simple to understand and easy to use, keeping the focus on what matters most – finding the fun.

APEX XPLR REAR DERAILLEUR 
You want your bike to do everything, so you need gears that can do everything. The Apex XPLR derailleur hits the sweet spot of smooth jumps over a big gear range, all with unmatched chain security and the simplicity of a 1x drivetrain. Quietly and quickly shift across our 12-speed cassettes with 44T large cogs, knowing you’ll have the gears you need.

• Compatible with cassettes with 44T large cogs
• Use with Flattop chain
• Works with 12-speed mechanical Apex and Eagle shifters
• Clutch controls chain tension for consistent shifting
• X-HORIZON straight parallelogram design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force

APEX WIDE CRANKSET
A single chainring with a wide-range cassette is a wonderfully clean way to tackle so many disciplines, and we’re the 1x leaders. Our Apex 1 Wide crankset features aluminum crankarms, a light and stiff DUB spindle, and elegant and secure direct-mount X-SYNC chainrings for flawless chain management. The wide chainline accommodates wider tires for any type of adventure.

XPLR CASSETTE
Maximum range, minimum fuss. This 12-speed 11-44T cassette provides 2x range in a 2x package and fits on a traditional 11-speed driver body for broad integration. The smooth cog progression keeps jumps between cogs tightest when it’s time to go fast, with more meaningful gaps for climbing.

• 12-speed
• Flattop technology allows for a narrower chain with quieter operation and increased strength and durability
• Includes Flattop PowerLock
