OROME Valar SK40D Carbon Disc Wheelset – 40mm Six-Spoke

Six carbon spokes. 40mm aero rims. Just 1,378g per pair.

Looking for carbon wheels that stand out from the usual crowd?

The OROME Valar SK40D Carbon Disc Wheelset combines a distinctive six-spoke design with lightweight Toray T800 carbon construction and an aerodynamic 40mm rim profile.

Unlike conventional wheels with separate metal spokes, the SK40D uses one-piece carbon rim and spoke technology, creating an integrated aerodynamic structure designed for stiffness, responsiveness and efficient power transfer.

Weighing approximately 1,378g per pair, these wheels are designed for cyclists who want something different without compromising on performance.

Why Choose the OROME Valar SK40D?

• Six Integrated Carbon Aero Spokes: A distinctive aerodynamic design using one-piece rim and spoke technology.

• Lightweight at 1,378g: A lightweight carbon wheelset designed for responsive acceleration and climbing.

• 40mm Aerodynamic Rim Depth: Balances aerodynamic performance with versatility across varied terrain.

• Toray T800 Carbon Fibre: Lightweight carbon construction designed to balance stiffness, strength and ride comfort.

• 22mm Internal Rim Width: Supports modern wider road tyres and selected gravel tyres.

• Tubeless Ready: Compatible with suitable tubeless tyres or conventional clincher tyres with inner tubes.

• TPI Ceramic Bearings: Six ceramic bearings across the hubs for smooth wheel rotation.

• 36T Star Ratchet Hub: Provides responsive engagement when accelerating or applying power.

• Centrelock Disc Brake Compatibility: Designed for modern disc brake road bikes.

What Makes Six-Spoke Carbon Wheels Different?

Most carbon road wheels use a traditional rim-and-spoke construction, with individual spokes connecting the hub to the rim.

The SK40D takes a different approach.

Its six wide carbon aero spokes form part of an integrated carbon structure, creating a distinctive profile designed to manage airflow around the wheel.

The result is an aerodynamic wheelset with fewer, wider spokes rather than the numerous narrow spokes found on conventional wheels.

It's a design that looks different, but the real appeal is the combination of low weight, aerodynamic shaping and responsive performance.

A 40mm Rim Depth for Versatile Riding

Not every cyclist wants an 80mm deep-section wheel.

A 40mm rim offers a more versatile option, providing aerodynamic benefits without the additional depth associated with dedicated time trial wheels.

For riders tackling rolling roads, climbs, fast bunch rides and changing wind conditions, the SK40D offers a practical balance.

At approximately 1,378g per pair, it's also lightweight enough to appeal to riders who want their wheels to feel responsive when accelerating or climbing.

Road and Gravel Tyre Compatibility

The SK40D features a 22mm internal and 29mm external rim width, providing support for wider modern tyres.

The manufacturer specifies compatibility with suitable tyres up to 45mm wide, making the wheelset an option for road riding and selected gravel applications.

• Tubeless-ready carbon clincher rims

• 22mm internal rim width

• 29mm external rim width

• Manufacturer-listed tyre range: 23–45mm

• Compatible with suitable clincher tyres and inner tubes

For gravel use, confirm the intended riding conditions and tyre clearance before ordering. Compatibility with wider tyres does not automatically make every wheelset suitable for demanding off-road riding.

Who Are These Wheels Best Suited For?

• Road cyclists wanting distinctive six-spoke carbon wheels

• Fast bunch rides and club racing

• Hilly and rolling road routes

• Triathlon and time trial riders wanting a shallower aerodynamic option

• Riders upgrading from heavier alloy or carbon wheelsets

• Cyclists building a lightweight, aero-focused road bike

Technical Specifications

Frequently Asked Questions

What are the benefits of six-spoke carbon wheels?

The SK40D uses six wide carbon aero spokes instead of conventional individual metal spokes. This creates an integrated aerodynamic design intended to combine stiffness, low weight and aerodynamic performance.

Are the OROME SK40D wheels suitable for climbing?

Yes. At approximately 1,378g per pair, the SK40D offers a lightweight setup for climbing and acceleration, while the 40mm rim depth provides aerodynamic benefits on faster sections.

Can I use the SK40D wheels for gravel riding?

OROME lists the SK40D for road and selected gravel use, with tyre compatibility up to 45mm. However, suitability depends on the riding conditions, tyre selection and manufacturer restrictions. Check before using them for rough or technical gravel riding.

Are these wheels tubeless compatible?

Yes. The SK40D rims are tubeless ready and can also be used with compatible clincher tyres and inner tubes.

What's the advantage of ceramic bearings?

Ceramic bearings can reduce bearing friction and offer corrosion resistance. Actual performance depends on bearing quality, lubrication, sealing and ongoing maintenance.

Will these wheels fit my road bike?

The SK40D uses Centrelock disc brakes, a 12x100mm front thru-axle and a 12x142mm rear thru-axle. You'll also need to check cassette/freehub compatibility and available tyre clearance.
