Crafted to perform

Our Carbaura Road wheel range has been designed to keep you one step ahead of the competition, mile after mile.

optimised for speed

Our Carbaura RC wheelsets have been built around an optimised, Computational Fluid Dynamics tested, aerodynamic profile in a Carbon Fibre chassis.

Thanks to tens of thousands of real world test miles, numerous lab tests and countless hours of refinement we were able to surpass our primary aims of designing a new wheelset with low weight, linear compliance and lateral stiffness.

Available in both 35 and 50mm depths, the Carbaura RC wheelsets are our fastest rim brake wheels ever.

Medium of construction

To reduce weight and increase power transfer, there is no better material than Carbon Fibre when it comes to riding on the road.

The Carbon Fibre we use in the Carbaura RC wheels is Torayca ® T700, due to its incredible stiffness to weight ratio.

The sourcing and manufacturing of Torayca ® T700 has been done so in a way in which we are proud to put our name behind, where environmental impact is minimised.

Turning up the volume

To deliver enhanced comfort and grip, as well as reducing rolling friction, our Carbaura RC wheels use 19mm internal and 25mm external rim widths.

The wide profile rim is ideally suited to tyres ranging from 25 to 35c. Using 25c tyres will offer optimum aerodynamic performance by reducing unwanted drag, whereas using a wider tyre, such as 32c, will greatly improve small bump compliance, helping you conquer the cobbles.

Brake away from the pack

To improve braking performance and rim durability on tough alpine descents, the braking surface has been finished in a 1.5k weave. This finish ensures heat is dissipated throughout the carbon structure faster, dramatically reducing temperature build up. Braking has been engineered to work with a proprietary brake pad - the SwissStop Black Prince.

The centre of the Carbaura RC

At the very core of the Carbaura RC wheels are our RS Front and RS 6Drive hubs.

Both the front and rear hub use Japanese made, fully sealed EZO bearings for longevity, regardless of the weather.

Our RS 6Drive hub features 6 individually sprung reversed pawls, mounted into the hub shell, that simultaneously engage into the 30-point freehub driver for positive torque transfer.

Tying it together

Hand crafted with lightweight bladed aero spokes to decrease aerodynamic resistance, and widely spaced hub flanges for strength, the Carbaura RC wheelsets have been built to reduce any possible lateral flex and increase power transfer.

The rear wheel uses a 16/8e lacing pattern to balance spoke tensions and withstand torque forces, whilst the front wheel uses radical lacing to reduce weight and further improve aerodynamics.

16/8e spoking puts the mass of the spokes where they are needed most, in this case, on the rear wheel, drive side. This ensures that with every turn of the cranks, power is utilised efficiently and not lost in spoke flex.

Tested Results

To ensure that the Carbaura RC wheelsets achieve the drag coefficient they were designed to achieve, we directly compared it against our previous generation Carbarua RD38 and RD50 wheels, as well as our current Devaura, deep section aluminium wheel.

As expected, our Carbaura RC50 are our most efficient wheelset to date, saving you an impressive 29secs over 40km when compared to the Devaura in drag alone - before taking any weight savings into account.

We've optimised our wheels for aerodynamics without compromising handling. The RC35 is similar in drag to our previous 50mm depth rims, but in fact better at increased yaw angles, meaning better control in crosswinds without losing any advantage in out-and-out speed.

The Carbaura RC wheelsets underwent extreme lab testing in areas such as; impact tests, wheel rotation accuracy, extreme tyre pressures, prolonged imperfect road surface rolling, static stiffness, spoke hole strength, brake heat dissipation as well as the above drag coefficient tests.

The complete package

The complete wheelset is supplied pre-tubeless taped with SwissStop Black Prince pads and our own padded travel bag.

The 35mm deep tubeless-ready Carbaura RCs from British company Halo are every millimetre the modern aero road bike wheel with their wide, bulbous profile Toray T700 carbon rims. And while aerodynamics are more important than weight, these are decently light too.

Carbauras accelerate sharply, keep their speed very well and were noticeably quicker than the non-aero wheels that they replaced. The build quality also appears to be very good and they’re stiff too, with no noticeable flexing even during high-torque efforts.
