*NEW* OROME VALAR CS50D 50mm Wave Carbon Disc Wheelset

Lightweight 50mm carbon wheels designed for fast road riding.

The OROME VALAR CS50D combines wave-profile carbon rims, flat carbon spokes and ceramic-bearing hubs in a wheelset with a claimed weight of just 1225g ±15g.

The 50mm wave rim varies in depth around the wheel and is designed to balance aerodynamic performance with predictable handling in changing wind conditions. With a 23mm internal rim width, the CS50D also provides a modern platform for wider road tyres.

This is a performance-focused wheelset for riders looking for quicker acceleration, responsive handling and the aerodynamic benefit of a deeper carbon rim.

Key features

• 50mm wave-profile rims: Designed to reduce aerodynamic drag while maintaining stable handling at speed.
• Low wheelset weight: A claimed weight of 1225g ±15g keeps the CS50D exceptionally light for a 50mm carbon wheelset.
• Toray T800 carbon construction: Used to create a lightweight, stiff and responsive rim.
• 5.2mm flat carbon spokes: Reduce weight and provide a direct, responsive feel under acceleration.
• 23mm internal rim width: Provides a modern platform for wider road tyres.
• Tubeless ready: Suitable for use with compatible tubeless road tyres.
• 60-tooth star-ratchet hub: Provides quick engagement when accelerating or getting back on the power.
• Custom ceramic bearings: Designed to help minimise resistance within the hubs.
• Titanium-alloy freehub body: Combines low weight with improved resistance to cassette marking compared with a conventional aluminium freehub body.
• Hand-built: Each wheelset is assembled and checked for spoke tension and trueness before leaving the factory.

Designed for fast road riding

The VALAR CS50D is designed for riders who want the speed of a 50mm carbon wheel without the usual deep-section weight penalty.

Its combination of low weight, aerodynamic rim depth and stiff carbon spokes makes it particularly well suited to:

• Road racing
• Fast bunch and club rides
• High-speed training
• Rolling and undulating courses
• Sportives and endurance road events
• Riders looking for one lightweight aero wheelset for varied road terrain

Rim and tyre compatibility

The CS50D features a tubeless-ready carbon rim with a 23mm internal width and 29.5mm external width. This wider profile is designed to support modern road tyres and create a smoother transition between the tyre and rim.

Always use compatible tyres and follow the pressure limits specified by both the tyre and wheel manufacturers.

Freehub options

• Shimano HG 11/12-speed
• Shimano Micro Spline Road (MSR)
• SRAM XDR

Please select the freehub option that matches your cassette and groupset. If you’re unsure which option you need, contact us before ordering.

Specifications

Frequently asked questions

What is the benefit of the wave-profile rim?

The rim depth rises and falls around the wheel rather than remaining constant. This profile is designed to provide the aerodynamic benefit of a deeper rim while improving handling in changing wind conditions.

Who is the CS50D designed for?

It is designed for fast road riding, racing and high-speed training. Its low weight also makes it suitable for riders who want a deep-section wheelset that still feels responsive on rolling or undulating roads.

Which freehub option do I need?

Most Shimano road cassettes use the Shimano HG option. SRAM road cassettes with a 10-tooth smallest sprocket generally require SRAM XDR. Shimano MSR is available for compatible Shimano setups. Contact us with your groupset or cassette details if you’re unsure.

Are replacement carbon spokes available?

Carbon spokes are more specialised than conventional stainless-steel spokes. We recommend checking replacement-part availability and servicing requirements before purchasing if this is a priority for you.
