GC-Forty Disc 28" / 700 C Gravel Front Wheel | 24 Spokes

The ROSE GC-Forty Disc Carbon Gravel front wheel is the Gravel King in our ROSE racing family.
With its 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 inner width of 24 mm for wide tyres results in a real race feeling and massive comfort at the same time. The rim material absorbs a large part of the resulting vibrations and thus improves ride comfort not only on the road, but especially on rough surfaces thanks to its damping properties.

Everything stands and falls with the rim!

The high-end carbon rim of the ROSE RC-Forty Disc gravel 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 gave the rim a full inner width of 24 mm and “tubeless-ready” compatibility ex works. Naturally, you can also ride the GC-Forty Carbon rear wheel in a conventional way with conventional tyres and inner tubes.
Thanks to the asymmetric and bulbous rim profile, the carbon rim not only minimises air resistance at high speeds on dusty gravel roads, but also reduces annoying air turbulence. Even strong crosswinds are optimally dissipated. As a rider, you’ll feel fully in control over your gravel bike in every riding situation.

ROSE made by NEWMEN!
The GC-Forty Disc Carbon front 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 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 GC-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.
