剎車變速桿 - Sram Apex Mechanical Shift-Brake Control
SB-APX-B1

When you choose to ride, advancement means having a group that's always ready. Apex 1® is that group. The Apex® 11-speed mechanical shift-brake control gives you all the gears you need in the palm of your hand. It's technology that makes cycling easier-so you can tune into the experience and build on it.

• ErgoFit™ design from SRAM RED® improves grip and finger wrap
• Individual Reach Adjust of brake lever and shift paddle for a perfect fit
• Zero Loss™ means immediate engagement of your rear derailleur as soon as you touch the shifter.
• Durable, forged aluminum lever blade with laser texture for a positive touch

DOUBLE TAP
Double Tap makes changing gears easier and faster, eliminating the cumbersome and awkward engagement associated with two-lever systems. doubleTap handles up- and downshifts in one short, sweeping motion, with minimal effort and maximum comfort no matter where you are on the bars.

ERGODYNAMICS
Longer brake levers, independent reach adjust for the brake and shift levers, and optimized hood shape gives riders of any size comfort and easy access to the controls.

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). EA helps to simplify and stabilize 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.

REACH ADJUST
Brake lever fit and feel is a personal thing. Riders have individual positioning preferences, as well as unique hand sizes and finger lengths. Reach Adjust makes it easy to adjust your lever for maximum one~finger control for everyone.

ZERO LOSS
ZERO LOSS simply means, well, zero loss - when you push on the lever, for an upshift or down shift, the cable is engaged instantly - zero loss of movement. There is no middle- ground where you're waiting for the shift to come. Gear changes are instant and precise.
