BERG rim 29″ Ratheberg 30 28-hole UD carbon 290g

The founders of the young BERG brand started with a simple mission: They wanted to develop the best possible lightweight products for ambitious MTB marathon and cross-country riders at an affordable price. In order to be prepared for tough racing use, no compromises were made in terms of durability when developing the BERG components. Behind the brand is a small team of committed mountain bikers, engineers and bike mechanics from Belgium.

The BERG Ratheberg rims play in the absolute top league among lightweight rims for XC racing. Its combination of an above-average inner width of 30 millimeters with a weight of around 290 grams is record-breaking. In practice, this results in a rim that is extremely easy to accelerate and a tire that runs very stably, even at very low air pressures. In addition, the large inner width allows tires up to 2.7″ wide to be used. The tubeless inner profile ensures that the tire sits securely on the hookless rim. The low weight of the hand-made rims was due to the relatively low profile height of only 21 millimeters can be realized.The asymmetrical spoke holes with an offset of 2 millimeters ensure the necessary rigidity in the wheel.A reinforced rim bed provides the spoke nipples with secure support and makes the wheels more stable.
In order to guarantee the safety of your components, all BERG components have undergone extensive tests according to the ISO standard in Germany in addition to intensive test drives. In order to guarantee the high quality standards in the long term, the tests are repeated on different product batches.
In addition to the 2-year guarantee, BERG offers a 3-year crash replacement with a 40% discount on all components.
