Shift simply, attack fully.
The SRAM Apex 1 crankset with 170 mm crank arm length, 40-tooth chainring, and GXP axle is the ideal foundation 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 simple, robust, and attractively priced 1x setup without compromising on performance. The integrated 4-arm spider provides an excellent stiffness-to-weight ratio, while the 40-tooth chainring offers a versatile compromise between propulsion on the road and climbing capability off-road. Thanks to the crankset's special design, it also provides more tire and frame clearance than many classic road bike cranksets - perfect for wide gravel or all-road tires.
Highlights:
- 1x11 setup: streamlined drivetrain with just one chainring - less weight, less wear, and simple shifting.
- X-SYNC™ tooth profile: precisely machined Narrow-Wide teeth for perfect chain retention and smooth running.
- GXP axle: compatible with proven SRAM GXP bottom brackets.
- More tire clearance: approximately 2 mm of additional space per side compared with classic road bike cranksets.
- Aluminum construction: sturdy aluminum crank arms and chainring - robust and suitable for everyday use.
