*NEW* OROME VALAR CS50A 50mm Wave Carbon Disc Wheelset
Lightweight 50mm carbon wheels combining aerodynamic performance with proven, easily serviced Sapim CX-Ray spokes.
The OROME VALAR CS50A is designed for fast road riding, combining Toray T800 wave-profile carbon rims, Sapim CX-Ray aero spokes and ceramic-bearing hubs in a wheelset weighing a claimed 1310g ±15g.
Its 50mm wave-profile rims are designed to provide the aerodynamic benefit of a deep-section wheel while supporting more predictable handling as wind conditions change. A modern 23mm internal rim width provides a suitable platform for wider road tyres.
The CS50A offers riders a practical balance of speed, low weight and serviceability. Its stainless-steel spokes are considerably easier to source and replace than specialised carbon spokes, making this a strong option for regular training, racing, fast club rides and longer road events.
Key features
- 50mm wave-profile rims: Designed to combine deep-section aerodynamic performance with more predictable handling in changing wind conditions.
- Low wheelset weight: A claimed weight of 1310g ±15g makes the CS50A exceptionally light for a 50mm wheelset using stainless-steel spokes.
- Toray T800 carbon construction: Used to balance rim stiffness, strength and low weight.
- Sapim CX-Ray spokes: Proven stainless-steel aero spokes offering low weight, strength and straightforward replacement if required.
- 23mm internal rim width: Provides support for modern wider road tyres.
- Tubeless ready: Suitable for use with compatible tubeless tyres.
- 60-tooth star-ratchet hub: Provides quick engagement when accelerating or getting back on the power.
- Ceramic bearings: Designed to provide smooth and efficient hub operation.
- Aluminium-alloy freehub body: Helps keep the wheelset weight down while allowing straightforward servicing.
- Hand-built: Each wheelset is assembled and individually checked for spoke tension and trueness.
Designed for fast road riding
The VALAR CS50A is designed for riders who want the speed of a 50mm carbon rim without giving up everyday practicality.
Its combination of low weight, aero rim depth and serviceable Sapim spokes makes it particularly well suited to:
- Fast bunch and club rides
- Road racing
- High-speed training
- Rolling and undulating routes
- Sportives and endurance road events
- Riders wanting one lightweight aero wheelset for regular road use
Why choose the CS50A?
The CS50A uses Sapim CX-Ray stainless-steel spokes, one of the most widely used performance spokes in cycling. Their bladed profile is designed to reduce aerodynamic drag, while their widespread availability makes replacement and servicing relatively straightforward.
This gives the CS50A an important practical advantage for riders who regularly train, travel or race with their wheels. You still get an impressively low claimed weight and the CS50 wave-profile rim, without relying on specialised carbon replacement spokes.
Wave-profile carbon rims
Instead of remaining at one constant depth, the rim rises and falls around the wheel. This wave profile is designed to retain the aerodynamic benefit of a deep carbon rim while reducing abrupt steering input as the strength or direction of a crosswind changes.
No 50mm wheel is unaffected by strong winds, but the CS50A is designed to provide more predictable handling than a conventional constant-depth rim in changing conditions.
Rim and tyre compatibility
The CS50A features a tubeless-ready carbon rim with a 23mm internal width and 29.5mm external width. This wider platform provides better support for modern road tyres and helps create a smoother transition between the tyre and rim.
Actual tyre width can vary depending on the tyre model, rim and pressure. Always check frame and fork clearance and follow the pressure limits specified by both the tyre and wheel manufacturers.

Frequently asked questions
What is the benefit of the wave-profile rim?
The rim rises and falls in depth around the wheel rather than remaining constant. It is designed to retain the aerodynamic benefit of a deep rim while supporting more predictable handling when wind conditions change.
Are Sapim CX-Ray spokes easy to replace?
Sapim CX-Ray spokes are widely used by wheel builders and bike shops around the world. They are generally easier to source and replace than proprietary carbon spokes, making the CS50A a practical option for regular riding and racing.
How does the CS50A differ from the CS50D?
Both models use 50mm wave-profile Toray T800 carbon rims. The CS50A uses Sapim CX-Ray stainless-steel spokes and an aluminium-alloy freehub body, with a claimed weight of 1310g ±15g.
The higher-spec CS50D uses flat carbon spokes and a titanium-alloy freehub body, reducing its claimed weight to 1225g ±15g. The CS50A is the more practical choice if straightforward spoke replacement and servicing are important, while the CS50D prioritises the lowest possible weight and a stiffer carbon-spoke build.
Which freehub option do I need?
Most Shimano road cassettes use Shimano HG, while 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 cassette or groupset details if you’re unsure.
