Simple shifting, full attack.

The SRAM Apex 1 crankset with 170 mm crank arm length, 40-tooth chainring, and GXP axle is the ideal basis for a modern 1x11 drivetrain on a road bike, gravel bike, or commuter. Thanks to the proven X-SYNC™ narrow-wide tooth profile, the chain stays securely on the chainring even on rough terrain – without a front derailleur.

The crankset is aimed at anyone who wants to ride a simply designed, robust, and attractively priced 1x setup without sacrificing function. The integrated 4-arm spider ensures an excellent stiffness-to-weight ratio, while the 40-tooth chainring offers a versatile compromise between propulsion on the road and climbing ability off-road. Thanks to the special design of the crankset, it also offers more tire and frame clearance than many classic road bike cranksets – perfect for wide gravel or all-road tires.

Highlights:

• 1x11 Setup: clean drivetrain with only one chainring – less weight, less wear, simple shifting.
• X-SYNC™ Tooth Profile: precisely machined narrow-wide teeth for perfect chain guidance and smooth running.
• GXP Axle: compatible with proven SRAM GXP bottom brackets.
• More Tire Clearance: approx. 2 mm additional space per side compared to classic road bike cranksets.
• Aluminum Construction: sturdy aluminum crank arms and chainring – robust and suitable for everyday use.
