R-Thirty Disc LIGHT 27.5″ / 650 B Road Bike Rear Wheel SRAM XDR | 24 Spokes

Don’t let the name fool you!

The ROSE R-Thirty Disc LIGHT rear wheel is more than just a slightly lighter version of our successful R-Thirty Disc system wheel.
Even if the specs of the robust aluminium rims seem nearly identical, the devil is once again in the details. More on that later…
In terms of range of use, our LIGHT rear wheel is also a true all-purpose weapon. With its middle-high rim profile it fits right in almost anywhere – doesn’t matter if it’s a fast marathon racer, explosive cyclo-crosser, sprightly gravel bike or travel-ready randonneur.

ROSE made by NEWMEN!

The R-Thirty Disc LIGHT 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. In the rear wheel hub, a 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.

And what about the rim?

The special geometry of our ROSE made by NEWMEN hub means that the geometry of the rim profile also had to be adjusted. We gave the rims an asymmetric profile with 3 mm offset for optimal spoke tension, resulting in a stiff and resilient wheel. The combination of hub, rim, and robust Sapim Laster TCS Straightpull spokes works so well, that our R-Thirty Disc LIGHT rear wheel with “only” 24 spokes is just as robust, stable, and reliable as the more affordable model with 28 spokes. While being somewhat lighter and providing more performance. And last, but not least, “tubeless-ready” of course!

Of course you can also ride the R-Thirty Disc LIGHT rear wheel in a conventional way with classic tyres and inner tubes.

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.
