Since the foundation of our company 1907, our passion for cycling in all its facets has enabled us to gain valuable experience in the development of high performance rims. With our manually laced RC-Fourty/Fifty Disc Carbon wheelset for your road bike with disc brakes, we present, after more than one and a half years of development, the current ROSE pioneer in terms of aerodynamic, performance and weight. All this garnished with a convincing, simple design and an outstanding price-performance ratio.
With 47 mm high rims on both the front and rear wheels, the RC-Fourty is predestined for race bikes. But this wheel set also does not shy away from trips to time trials or triathlons.

It's all about the rim

The noble carbon rims of the ROSE RC-Fourty/Fifty Disc road bike wheelset are a complete in-house development and have special construction that makes them very light and yet stable and resistant. Of course, we follow the trend towards wider tyres and therefore grant the rim a full inner width of 19 mm and “tubeless-ready” compatibility ex works. Of course you can also ride the RC-Fourty/Fifty wheels in a conventional way with conventional tyres and inner tubes.
The high-quality carbon brake flanges in combination with the Flash Evo Black Prince Road brake pads from SwissStop, which are included in the scope of delivery, also convince with excellent braking behavior and rich deceleration.
Thanks to the asymmetrical, rounded rim profile, the carbon rims not only minimize air resistance, but also reduce annoying air turbulence. Even strong side winds are optimally dissipated. As a rider you feel full control over your road bike in every riding situation and you save valuable energy for the really important duels on the track. Be it against your competitors in the sprint, against the mountain on a 15% gradient or simply against yourself and your weaker self.

Newmen & ROSE - “centerpiece” made in Germany

We didn’t want to compromise on the hubs! That’s why they come from Newman - a small but fine high-performance company that both designs and tests as well as produces in the Allgäu. The CNC-milled hub body with the lowest tolerances has a high material thickness at the neuralgic points and thus large safety reserves. At other points, the material could again be reduced to such an extent that a very low hub weight was nevertheless achieved. In the rear wheel hub, a freewheel with a precise ratchet system also ensures direct traction and maximum propulsion. The high-quality, double-sealed industrial bearings with our specially developed high-performance grase filling guarantees reliable and long-lasting function as well as extremely simple operation. An often complicated adjustment of the bearing clearance is not necessary.

Robust aero spokes and inverted nipples

20 radial spoked SAPIM CX-Sprint Straightpull Aero spokes in the front wheel provide a stable and reliable connection between the Newman hubs and ROSE RC-Fourty/Fifty carbon rims. For the rear wheel we rely on a combination of 7 radially mounted SAPIM CX-Ray spokes on the left side and 14 2-crossed SAPIM CX-Sprint aero spokes on the drive side, which is subject to much higher loads. In this way the occurring forces are optimally transmitted and a stiff and stable wheel is guaranteed, which at the same time is characerised by very low weight.
The reliable SAPIM aluminium spoke nipples are located particularly aerodynamically inside the rim and are mounted invertedly. The nipple is supported on conically shaped SAPIM nipple washers, which ensures and even distribution of the load and thus a relief of both the spokes and the rims. This drastically reduces the probability of spokes breaking.

Nothing beats honest craftmanship

In line with our long-standing company tradition, we completely dispense with machine spoking in the ROSE RC-Fourty/Fitfy disc wheelset. Instead, each individuell wheel is spoked and centred by hand at our company headquater in Bocholt. This way, our experienced wheel builders guarantee the best possible quality in spoke tension and concentricity.

In the box:
ROSE RC-Fourty Disc Carbon Road Bike wheelset incl.
• Tubeless ready rim tape (pre-assembled, suitable for conventional inner tubes)
• ROSE Tubeless valves
• M9/M10 quick release axles for front and rear wheel
• SwissStop Road Flash Evo Black Prince brake pads for carbon rim flanges

Due to our high-quality and very durable grease filling and the fixed bearing clearance, the hub bearings can run somewhat heavier at the beginning. However, this has no effect on the riding and disappears after a short running-in time.
The rims are explicitly approved ONLY for the use with SwissStop Road Flash Evo Black Prince brake pads for carbon rim flanges. Other brake pads (including carbon brake pads) must not be used.
For suitable brake pads see prod. code: 2284477.
The tubeless sealant is not included in the delivery.
