ELILEE X310 Carbon Crankset

Lighter. Stiffer. Faster.

The ELILEE X310 is the evolution of one of the most respected lightweight carbon cranksets on the market. Building on the success of the flagship X320, the all-new X310 has been completely re-engineered to deliver an even better balance of weight, stiffness and efficiency.

The result is a crankset that's 30g lighter than its predecessor (24mm version), 12% stiffer, and capable of weighing as little as 530g complete with a compatible power meter spider and lightweight chainrings.

Designed for riders who refuse to compromise, the X310 delivers exceptional power transfer, broad compatibility and class-leading engineering in one of the lightest production cranksets available today.

Best-in-Class Stiffness-to-Weight Ratio

Making a crank lighter is relatively straightforward.

Making it lighter and significantly stiffer is considerably more difficult.

Compared with the previous X320, the X310 delivers a 12% increase in stiffness while reducing weight by 30 grams, creating one of the best stiffness-to-weight ratios available in a production carbon crankset.

ELILEE benchmarked the X310 against leading cranksets from Rotor, SRAM and Easton, with the X310 delivering the highest stiffness-to-weight ratio during comparative testing.

The result is a crankset that responds instantly under load, whether you're sprinting, climbing or riding at threshold.

Built to Perform. Proven to Last.

Lightweight performance means nothing without reliability.

The X310 has successfully passed ISO4210:2015 fatigue testing and has been destruction tested to 420kg, exceeding the loads recorded for several leading premium cranksets during ELILEE's internal testing.

Every crankset has been developed to combine exceptional responsiveness with the long-term durability demanded by elite racing and high-mileage riding.

Proven at the Highest Level

For the 2026 season, Team Bahrain Victorious selected the ELILEE X310 Team Edition crankset and power meter as part of its partnership with ELILEE.

Chosen for its exceptional stiffness-to-weight ratio and race-proven reliability, the X310 is now trusted by riders competing at the highest level of professional cycling.

Why We Stock It

At Off The Front, we look beyond headline weight figures. The ELILEE X310 impressed us because it delivers something far more valuable—a genuine improvement in stiffness without adding weight.

Combined with its broad compatibility, premium titanium and aluminium spindle options, Easton Direct Mount ecosystem and proven race pedigree, the X310 is one of the most exciting carbon cranksets available today.

For riders building an uncompromising race bike, it's a benchmark for modern crankset design.
