Product Details

Overview & Technology

Easton’s EA90 SL Disc front wheel is built around a 27mm-deep, double-wall aluminum rim with a 19.5mm internal width — optimized for modern 28–38mm road and endurance tires. The rim is tubeless-compatible and finished in a durable black anodized coat to resist scratches and the rigors of regular riding. The Vault CL hub is the technological heart: bigger bearings on a wider bearing stance and improved seals increase durability and stiffness under braking and cornering loads. A reversed drive ring layout delivers 60 points of engagement at just 6°, giving instant, confident power transfer when you surge or sprint.

Key Features & Construction

Materials and build: The EA90 SL rim is a double-wall 6061-series aluminum construction with 24-hole drilling and a 24mm external width to provide a stiff, predictable platform that pairs well with modern aerodynamic tire profiles. The rim’s 19.5mm internal width favors wider road and endurance tires for improved stability and lower rolling resistance. • Vault CL hub with larger bearings and improved seals for longevity. • Reversed drive ring for 60-point engagement, 6° engagement angle. • Tool-free, swappable end-caps to support QR / 12mm / 15mm through-axles. • Includes 5 extra straight-pull Sapim spokes and uniform spoke length for easier replacement and truing.

Fit, Compatibility & Specs

The EA90 SL Disc front wheel ships as a 700C / 622 wheelset front (position: Front) with Vault CL hub spacing of 100mm and Disc Center Lock rotor interface. Valve type is Presta and the rim is tubeless-compatible; skewers are not included. Tool-free swappable end-caps in the box make it simple to convert between QR, 12mm and 15mm thru-axle standards. Important specs at-a-glance: 27mm rim depth, 19.5mm internal width, 24H drilling, 24mm external width, double-wall aluminum construction, weight (shipping): 6.7 lb, manufacturer part #: 8022743, product #: 041533.

Who It's For

The EA90 SL Disc is aimed at road and endurance riders who want a durable, lightweight aluminum front wheel that works seamlessly with modern wider tires and disc brakes. It's an excellent choice for riders who value quick engagement for criterium-style accelerations but don’t want the expense or fragility of carbon rims. It also suits cyclists upgrading from stock wheels who need broad axle compatibility, straightforward maintenance (tool-free end-caps and spare Sapim spokes) and a tubeless-ready platform that improves ride comfort and puncture resistance on rough roads.

Frequently Asked Questions

Is the EA90 SL Disc wheel tubeless-ready?

Yes — the EA90 SL rim is tubeless-compatible. It accepts tubeless tires and can be set up with tape and sealant. For best results use tubeless-specific tape and a high-volume track pump or compressor to seat the bead.

Which axle standards does this front wheel support?

The wheel ships with tool-free swappable end-caps that allow conversion between QR (skewer), 12mm and 15mm thru-axles. The hub spacing is 100mm for front fitment. Skewers are not included in the box.

What does 60 points of engagement at 6° mean for my ride?

It means the Vault CL hub provides quick, nearly-instant engagement when you start pedaling, allowing immediate power transfer and snappy acceleration. The higher point count reduces dead-zone between pedal strokes, which is especially noticeable in criteriums and punchy climbs.

Can I replace spokes myself and are replacements included?

The wheel includes five extra straight-pull Sapim spokes that match the uniform spoke length used in the front wheel. This makes emergency roadside repairs or shop-level replacements simpler. For a durable repair, use Sapim-compatible spokes and have a qualified mechanic true the wheel if you're unsure.

Is this wheel suitable for rim brakes or only disc brakes?

The EA90 SL Disc is a disc-only front wheel featuring a Center Lock rotor interface and no brake track for rim brakes. It's designed specifically for disc brake-equipped road bikes.

How durable is the rim and hub for frequent riding?

The double-wall aluminum rim combined with larger hub bearings and improved seals gives this wheel a robust lifespan for everyday training and endurance use. With regular maintenance — keeping seals clean and bearings serviced when needed — the hub and rim should hold up well under high-mileage use.

Buying Guide

When choosing a front road disc wheel, match rim internal width to the tire widths you ride most often; the EA90 SL’s 19.5mm internal width is ideal for 28–38mm tires, offering better tire profile and stability compared to narrow rims. Also confirm hub spacing (100mm front) and rotor interface (Center Lock) to ensure fit with your frame and rotor system. Consider wheel weight, durability, and engagement: aluminum rims like the EA90 SL give a great balance of cost, strength and predictable handling, while the Vault CL hub’s 60-point engagement delivers a responsive feel that benefits crits, group rides and punchy hill attacks.
