The endurance performer of our road range: the acros Road Disc Rear Hub combines a modern straightpull design, an oversized 19 mm axle, premium angular contact bearings and our latest ratchet freehub technology for maximum efficiency and reliability.

Every hub is manufactured entirely at our headquarters near Stuttgart, Germany. Each hub shell is CNC turned and CNC machined from a solid bar of high-quality 6061 aluminium before being carefully assembled by hand. The result is exceptional manufacturing precision and uncompromising quality.

As bearing specialists, we place great emphasis on the hub's internal design. The oversized 19 mm axle rotates on specially optimised stainless steel angular contact bearings, delivering exceptionally smooth running, high stiffness and long service life. The oversized axle concept allows the complete hub to be lighter while increasing overall wheel stiffness.

Instead of a traditional pawl mechanism, the rear hub features our precision ratchet freehub system, providing reliable engagement, efficient power transfer and excellent durability under all riding conditions.

Finished with a deep black high-gloss anodised coating, the hub combines a premium appearance with outstanding protection against corrosion, abrasion and environmental influences.

In-house manufacturing

At the heart of our product line are our nineteen hubs, manufactured at our headquarters in Renningen near Stuttgart. Here, we combine technical expertise, the highest quality standards, and precision manufacturing with a clear focus on durability. The result is hubs that impress with their reliability, efficiency, and long-lasting performance.

Let the riding do the talking

It doesn’t always have to be loud. Quite the opposite. The freehub of our rear hub can be adjusted to three different sound levels, so you can dial in exactly the sound that fits your ride. Add to that a subtle, all-black look: matte rims, glossy decals, clean branding. Let others shout — we’d rather let the grin on your face do the talking.

If needed, the bearings can be replaced easily by yourself, without special tools and without detours to the workshop. With our DIY tool, your wheelset will be ready for new adventures in no time.
