RC-Forty Disc 28" / 700 C Carbon Road Rear Wheel SRAM XDR | 24 Spokes

The hand-laced carbon wheels of the ROSE RC series are the current reference in terms of aerodynamics, performance and weight from ROSE Bikes for your road bike with disc brakes!
This also applies to our ROSE RC-Forty Disc rear wheel with its 37 mm high rim profile. It is predestined for maximum performance on your high-end race or endurance bike and cuts an excellent figure on demanding mountain stages as well as on long distances.

Everything stands and falls with the rim!

The high-end carbon rim of the ROSE RC-Forty Disc road wheel was fully developed in-house and has a special construction that makes it very light and yet stable and durable. Of course, we follow the trend towards wider tyres and therefore gave the rim a full inner width of 19 mm and “tubeless-ready” compatibility – no upgrades needed. Naturally, you can also ride the RC-Forty Carbon rear wheel in a conventional way with conventional tyres and inner tubes.
Thanks to the asymmetrical and bellied rim profile, the carbon rim not only minimizes air resistance, but also reduces annoying air turbulence. Even strong crosswinds are optimally dissipated. As a rider you can feel full control over your road bike in every riding situation and 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 you and your weaker self.

ROSE made by NEWMEN!
The RC-Forty Disc Carbon rear wheel uses our high-quality ROSE made by NEWMEN hub from the FADE hub generation by NEWMEN.
Its elegant, CNC-milled hub body made from high-quality aluminium is equipped with high safety reserves but still maintains a low hub weight. The large FADE freewheel system with a precise ratchet system also ensures direct engagement and maximum propulsion. The large size of the FADE system reduces the forces occurring within the freewheel and the newly-designed tooth profile ensures significantly less freewheel noise. The three pawls are designed to be very short and wide, which provides a more even distribution of and therefore reliable and material-friendly power transfer. The high-quality, double-sealed industrial bearings ensure smooth-rolling and long-lasting functionality as well as extremely simple operation. A frequently 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 hub and ROSE RC-Forty carbon rim. 24 spokes and the 2-fold crossed lacing are designed to handle high loads when used with 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 improves after a short running-in time.
