Compatibility
SRAM Apex Shift-Brake Lever is a SRAM shifter. It is a 12-speed component. It uses Cable shifting. Everything listed below was matched on a specification we hold for both parts: the interface each pairing actually depends on, such as freehub body, speed count, actuation or mounting standard. Where we could not verify that interface, the part is left out rather than assumed to fit.

Frequently Asked Questions
What fits SRAM Apex Shift-Brake Lever?
On this page we list handlebars with a matching shifter mount type (not clamp fit), front derailleurs this shifter drives. Each listing was matched on a specification we hold for both parts; anything we could not verify is omitted rather than assumed to fit.
Does SRAM Apex Shift-Brake Lever work with electronic shifting like Di2 or AXS?
No. SRAM Apex Shift-Brake Lever is mechanical, cable-actuated. Electronic groups use internal motors and proprietary signalling, so there is no mechanical or electrical path between the two.
Is SRAM Apex Shift-Brake Lever compatible with rim brakes?
No. SRAM Apex Shift-Brake Lever is built for hydraulic disc systems. The mounting standards and wheel/frame interfaces for disc brakes are different and cannot be mixed.
