Details

The ROSE GC-Forty Disc Carbon Gravel wheelset is the Gravel King in our ROSE racing family. With the elegant carbon rim designed for adventure, you'll race over demanding off-road tracks with ease. The combination of a medium-high rim profile of 37 mm and a wide inner width of 25 mm for wide tyres results in a real race feeling and massive comfort at the same time. The carbon absorbs shocks, thus improving ride comfort and cushioning your ride not only on the road, but also on rough surfaces.

Everything stands and falls with the rim

The high-end carbon rims of the ROSE RC-Forty Disc gravel wheelset were fully developed in-house and have a special construction that makes them very light and yet stable and durable. Of course, we follow the trend towards wider tyres and gave the rim a full inner width of 25 mm and “tubeless-ready” compatibility ex works.
Naturally, you can also ride the GC-Forty Carbon wheels in a conventional way with conventional tyres and inner tubes.
Thanks to the asymmetrical and bellied 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’ll feel fully in control over your gravel bike in every riding situation. Plus, you can save valuable energy for the really important duels in the Gravel Race. Be it against your competitors in a sprint, against the mountain on a 15% gradient or simply against you and your weaker self.

The hub is the "heart"

We didn’t want to compromise on the hubs! That is why they come from Newmen – a small but excellent material forge for high-end components. The CNC-milled hub body with the lowest tolerances has a high material thickness at the neuralgic points, e.g. the highly loaded transition between the front disc holder and the spoke flange, 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 grease 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

Strong SAPIM CX-Sprint Straightpull Aero spokes provide a stable and reliable connection between the Newman hubs and ROSE GC-Forty carbon rims. 24 spokes in the front and the rear wheel and the 2-fold crossed spoking are designed to handle high loads when used with the modern, powerful disc brakes. The reliable SAPIM aluminium spoke nipples lie aerodynamically inside the rim and are mounted inverted, so basically “wrong way around”. The nipple is supported on conically shaped SAPIM nipple washers, which ensures an 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 dispensed with mechanical spoking in the ROSE RC-Forty disc wheelset. Instead, each individual wheel is spoked and centred by hand at our company headquarter in Bocholt. This way, our experienced wheel builders guarantee the best possible quality in spoke tension and concentricity.

Attention:
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.
