Product Details

Overview & Technology

Easton EA70 AX is a purpose-built gravel front wheel that blends durable aluminum construction with a wide, tubeless-ready rim profile. The rim is a welded, double-wall aluminum design with a 24mm internal width and 27.5mm external width, engineered to cradle modern gravel tires and improve tyre shaping, comfort, and traction. Real-world benefits: the 20mm rim depth and wide 24mm internal channel make running 35–50C tires easy — maximizing contact patch and sidewall support for rough, mixed-surface rides. The X5CL center-lock hub uses sealed bearings and 12mm thru-axle compatibility (100mm spacing) for quick, precise fitment and reliable performance on long adventures.

Key Features & Construction

The EA70 AX pairs a double-wall aluminum rim with double-butted spokes for an ideal balance of strength, weight, and durability. The rim is tubeless-ready and drilled for 24 spokes, making it stiff enough for hard cornering yet compliant enough for long days on variable gravel. Valve type is Presta and the rim is optimized for tubeless sealant systems. Notable specs: welded tubeless-ready rim, 24mm internal width, 20mm depth, double-butted spokes, Center-Lock rotor interface, and X5CL hub model. Weights: 1670g for 650b (584 ISO) and 1760g for 700c — competitive for strong, day-to-day gravel use.

Fit, Compatibility & Maintenance

The EA70 AX is designed as a front wheel for modern gravel bikes. It uses a 12mm thru-axle (TA) with 100mm hub spacing and a Center-Lock disc interface for rapid rotor mounting. Rim drilling is 24 holes; hubs accept double-butted spokes, and the rim inner width range supports 22–27.9mm inner-width tires, with the ideal tyre profile being 35–50C. Skewers are not included — you'll need a compatible 12mm thru-axle for your frame. Bearings in the X5CL hub are sealed for low maintenance; periodic bearing checks, spoke tension inspection, and tubeless sealant top-ups will keep the wheel rolling smoothly season after season.

Who the EA70 AX is For

If you ride gravel, mixed-surface routes, or light bikepacking loops and want a reliable front wheel with modern width and tubeless capability, the EA70 AX is a strong choice. It's aimed at riders seeking a robust aluminum wheel that handles wider gravel tires without the cost or fragility of carbon. Gravel racers who value predictable tyre shape and every-ride durability, as well as adventure riders who want a dependable, repairable wheel, will appreciate the EA70 AX's construction and sensible spec. It's a practical upgrade for many gravel builds.

Frequently Asked Questions

Is the EA70 AX tubeless-ready?

Yes. The EA70 AX is a welded tubeless-ready rim designed to accept tubeless tires and sealant. With proper tubeless tape and a compatible valve, you can run lower pressures for better traction and fewer pinch flats. We recommend sealing and testing at home or at a shop if you're new to tubeless setups.

Which tire widths work best with this rim?

The rim's 24mm internal width is optimized for 35–50C gravel tires. That range produces an ideal tire profile for traction and stability on mixed terrain. It also supports slightly narrower or wider tires within the 22–27.9mm inner width tolerance, but for best handling stick to the 35–50C recommendation.

Does this wheel come with a skewer or thru-axle?

Skewers are not included. The EA70 AX is built for a 12mm thru-axle front with 100mm hub spacing. Make sure your fork accepts a 12mm thru-axle and that you have the correct axle hardware. Many modern gravel frames include a compatible thru-axle.

What rotor interface does the hub use?

The wheel uses a Center-Lock rotor interface for quick and secure rotor mounting. If your rotor uses 6-bolt mounting, you can use a Center-Lock to 6-bolt adapter ring. Center-Lock simplifies installation and alignment for on-trail rotor swaps.

Why are there different weights listed for 650b and 700c?

Wheel weight varies with rim diameter and material distribution. The EA70 AX is lighter in the 650b (584 ISO) size at 1670g because the smaller rim uses less material than the 700c variant, which is 1760g. Both are spec’d to keep strength high for gravel use while balancing weight.

How durable is the rim for rough gravel and light bikepacking?

Very durable. The double-wall welded aluminum rim construction combined with double-butted spokes provides strong impact resistance and resilience over rough roads and trails. While not as light as premium carbon wheels, this alloy design is repairable and better suited to the knocks of adventure riding.

Buying Guide

When choosing a gravel front wheel, prioritize rim internal width, hub compatibility, and tubeless readiness. A 24mm internal rim like the EA70 AX balances tire support for 35–50C gravel tires while remaining durable and easy to service. Match the wheel to your fork axle standard (12mm TA, 100mm spacing for the EA70 AX) and decide if you want the weight savings of 650b or the larger roll-over of 700c. Consider spare parts like a Center-Lock adapter, tubeless tape, and sealant when ordering.
