Apex 1 Wide DUB D1 Crankset

What Our Gearhead® Experts Are Saying:

“I’ve run this crank on both a gravel setup and a hardtail, and the cross-compatibility is the real win. The wider chainline clears big tires without forcing weird spacing, and the DUB spindle feels stiff without adding weight. Installing the direct-mount ring is quick, and chain retention with the X-SYNC profile has been rock solid for me, even on rough washboard descents.”

We count on the SRAM Apex 1 Wide DUB D1 Crankset to give our gravel and mixed-terrain bikes a clean, quiet, and simple 1x drivetrain. SRAM builds the Apex series with durability at the forefront, and that confidence shines through when we’re bouncing between chunky fire roads, slick singletrack, and loaded bikepacking routes without a hint of dropped-chain drama. Behind that easygoing ride experience is SRAM’s X-SYNC narrow-wide chainring, a DUB spindle tuned for long-term reliability, and a wider chainline that helps our frames fit bigger gravel tires without compromise. Paired with a wide-range cassette, it delivers smooth climbing gears and a crisp, efficient feel we trust on every adventure.
